Welcome to the first number of the Newsletter of the Center of Industrial Electronics of the Technical University of Madrid (CEI-UPM). This Newsletter aims to be a

periodical publication of our activities, outcomes, membership and any other information relevant to our daily life and progress.

In this first number, you may find a short summary of the outcome of the 2nd Annual Meeting of CEI-UPM, a reference to the 2009-10 edition of the Master/PhD on Industrial Electronics, a picture-based

introduction of CEI-UPM members and a short technical article on Energy and Efficiency. Besides, regular sections as “News briefs”, “New projects”, “Papers and publications” and any interesting piece of

gossip of CEI-UPM, will be periodically included in the Newsletter.

But, if you are not familiar with our activities, you may be wondering, What is CEI? CEI-UPM was created in October 2006 as a merger of two research groups: Industrial Electronics and Power Quality of

Electrical Service. The mission of the centre is to create knowledge and to develop applications related with industrial electronics, in close cooperation with industrial partners. The research lines covered by

CEI-UPM do not act as isolated divisions but try to generate synergies to tackle new problems with innovative solutions. The research activities run around power electronics, embedded digital systems and

power quality. Our way of doing is based on covering the research and development as a whole, including basic and applied research, development of new products applications and techniques, and innovation

transferred to the industrial sector. All these activities lean on three pillars: the professors, the students and the partner companies. The instruments used are mainly cooperation projects, with public and/or

private funding, and seminars and publications, for dissemination of results. CEI-UPM is now on a way to increase its research results, to be more international and to provide high-end research services and

know-how to the industrial sector.

We really appreciate if you send us any suggestion, question or comment to cei@upm.es. Enjoy reading this Newsletter!… and more will come in a few months!

Researchers-PhD Students

Meet the CEI-UPM members

CEI research activity is complemented with the research-

oriented Master/PhD on Industrial Electronics. The bridge

which connects both aspects, teaching and research, are the

students and professors who are, in many cases, CEI members.

The Master on Industrial Electronics is in its fourth academic

year. This new edition kicked-off on September 2009

incorporating novelties such as:

* Courses are taught in English in order to achieve the

challenge of making the CEI more international because this is

the only way to have the best researchers working with us, not

only from Spain, but from the whole world. It is a pleasure for us

to say that we are achieving that aim because 16 of our PhD and

Master students come from abroad.

* The number of credits offered has been increased and we

have included the possibility that the students don’t need to do

the whole Master to be accepted in the PhD. Now they can do

just 30 ECTS of the master, this one or another, to be accepted in

the PhD studies.

Some of the 60 credits ECTS of the Master belong to seminars

which are given by prestigious and well-know professionals in a

certain thematic area. This year the seminars will deal with

RFid, Electronic devices and Electronics in Space Applications

and they will take place on the second term period of the year.

Regarding some technical aspects of the master, it’s relevant to

highlight that its quality and excellence has been sufficiently

proved by the ANECA Quality Mention, reference MDC2006-

00376. This mention is applied to the PhD programme as most

of its subjects are grounded in Master subjects.

Currently, the number of enrolled students in the Master and

PhD programmes are 25 and 10, respectively, 45% of which come

from abroad (different countries) . This is a proof of the Master’s

undeniable international magnitude.

During the period which this newsletter is referred to, seven

students and CEI members as well, have finished their Master or

PhD studies. Congratulations!!

Society is becoming aware of the energy challenge for the next decades. We need to use the energy in a rational way to preserve this blue and green world while keeping our living

standards.

Limiting CO2 emissions means switching to a more electrical world. All electricity could be generated carbon-free from Hydro, Wind, Solar, Geothermal, Nuclear if we change the

way it is generated, transported, distributed, stored and consumed. Changes will take place at every power level, and every point of the energy chain, from the utility to the most

remote sensor. Most of the emerging electric power technologies presume active dynamic control of the electric energy flow, that is, requires the use of electronics.

Emerging smart grids integrate distributed generation with intelligent loads, to adapt generation and consumption, limiting energy process, transportation and energy storage. New Buildings will

require a dedicated power architecture, probably in DC, to integrate and control renewable energy, advanced storage, electric vehicles and smart loads.

Large Data Centers are adopting 380 Vdc power architecture, as an efficient alternative to the AC architecture. The “More electric aircraft” has adopted a 270Vdc bus to distribute the energy, which

combined with generators, fuel cells and smart motors has significantly changed the power architecture and reduced cost and weight.

Urban mobility is expected to suffer a great change in the future by traffic control and more rational vehicles, very likely electric, smaller and at lower speed. Supercapacitors, and new storage elements

will help in the direction of more efficient (energy recovery) and clean vehicles.

Local energy networks in autonomous or non-autonomous systems, like cars, ships, aircrafts, satellites, buildings or data centers require energy management. Knowledge in monitoring and sensors,

wireless control, active protection, communication, power management and bi-directional energy flow is needed. The stability of the system requires advanced models, dynamic control and active filters.

The goal is to take the energy from the energy source and provide it to the final load in the most controlled and efficient way. Electronic components, circuits and systems will play its role.

Energy is therefore a new driver for electronics, and the “Centro de Electrónica Industrial” has the human capital, the expertise, and the motivation to contribute with ideas, research and innovation to

this energy challenge. The role of power electronics in energy savings has been investigated in the EU project “Electronics Enabling Efficient Energy Usage (E4U)”, carried out by CEI, EUTEMA,

ECPE and TYNDALL. Additional details can be found in www.e4efficiency.eu

Politécnica de Valencia.• Welcome… to the new CEI-UPM members who have joined us during this period: Dejana Cucak (from Serbia) as full-time researcher and PhD student, and

Pablo Varela (from Spain), as full-time researcher and Master student.

Even if many of us could not believe that we could do it again, here we are with the second issue of the Newsletter of the Center of Industrial Electronics of UPM. This issuecovers the first half of year 2010, and once again we will try to show our main outcomes, news and maybe gossip .

Thus, once we took the first step, we have decided to “learn while we teach”. This is the reason why the CEI-UPM professors and researchers want to open our eyes and ears to new ideas, to new projects and wetry to interact as much as possible with our environment (students, colleagues, companies…).

The activities of CEI-UPM have consolidated during the last semester. We have launched our new web page, with a very innovative design made by Nueveuno, and we encourage you to visit it atwww.cei.upm.es. There are many subsections ready to be filled and more and more information will be feeding our web site to have a greater visibility and to have an information exchange reference in theIndustrial Electronics world. Another important event in terms of communication has been the 3rd Annual Meeting of CEI-UPM, celebrated in May. This event is becoming a periodical meeting point forcompanies, academics, researchers and potential CEI-UPM members. The details of this event can be found in a following section of this Newsletter. During this period, we have held the first edition of theAdvanced Seminars of the Master of Industrial Electronics. This year we have had three seminars covering three aspects of Industrial Electronics: Digital Control of power converters (by Prof. AleksandarProdic, Univ. of Toronto), Electronics in Space (Prof. Arturo Fernández, European Space Agency) and RFid, technology (Dr. Andrés García-Alonso, Donewtech). More details can be found below. And, ofcourse, we continue with our daily task, trying to offer our best to the environment and working with the same energy as the first day.

In this second issue we include the following sections. First, you will find a summary with the best of the 3rd Edition of the CEI-UPM Annual Meeting. The Advanced Seminars included in our Master/PhDprogram are also detailed in this page. We include a section related with Reconfigurable Hardware as one of the main research activities of CEI-UPM during the last years. This is a contribution made by Dr.Eduardo de la Torre. We include regular sections where we present News Briefs, including visits, projects, etc. and the lists of projects, papers, Thesis and outcomes of the last six months.

Preparing this Newsletter regularly is not an easy task, but thanks to the contribution of many CEI-UPM members, we are being able to complete our duties.We really appreciate if you send us anysuggestion, question or comment to cei@upm.es. Enjoy reading this Newsletter!… and more will come in a few months!

• CEI-UPM has participated in the exhibition Sueñosde Silicio, held in the building of Tabakalera in San Sebastian (from February 9th, to March 21st ). CEI-UPM has provided support for the installation of the work Protrude Flow of the Japanese artist Sachiko Kodama(see www.suenosdesilicio.es)

Traditional metrics to show how good or bad are electronic technologies are performance, energy consumption, resource occupation, or similar. However, flexibility and adaptabilityare getting close to the same importance levels.In order to show this fact, using today's well-known technologies, it is clear that a custom integrated circuit will probably perform much faster, consume less energy and requiresmaller silicon area than a microcontroller which solves the same problem by running an application software. Then, why is the software solution adopted in so many cases? Takingapart the cost reasons, which may decide one target technology or another, the other reason is flexibility.However, there are quite a large amount of application domains where performance requirements are pushing the limits and putting the microprocessor against the wall, while

maintaining the flexibility requirement of software applications. Solutions go on two directions: multi-processing systems, which get flexibility from the software, or reconfigurable systems, which maytake advantage of flexibility at hardware level. Not only that, if we think that the reconfigurable fabric can hold a variable number of custom processors, the so called MPSoC (Multi-Processor System onChip), we have full flexibility of HW and SW.Reconfigurabilty may contribute with added benefits in many application areas, but there are two important fields which may specially benefit from that unsurpassed flexibility: High performancecomputing Systems, and flexible embedded systems. In the area of High Performance Computing, many facilities which relied on clusters of hundreds or even thousands of microprocessors are moving toclusters of FPGAs, which may solve the problems faster and with smaller power consumption (could you figure out Google's electricity bill due to their server farms?). On the other area, the tendency forincreased complexity in some embedded applications are forcing the inclusion of reconfigurable resources in order to be able to cover the increasing computing needs under the real time restrictions. So,within this context, there are many reasons why these needs may change: new requirements appear through the product life, new standards (i.e.: communications emerge and are adopted rapidly), system'sfeatures may be improved, corrected or updated during product's life, user may decide to change operation conditions, systems may evolve and adapt to changing environments, ....There is still a lot of work to do in order to have some reconfigurable device inside everyone's personal computer or personal electronic gadget, but it is just a matter of waiting for the reconfigurabletechnologies to evolve a bit more, and the methods to come up with real reconfigurable applications to become more mature, to have this new generation of HW-flexible systems around as in an almostubiquitous manner, like today's microcontrollers. CEI-UPM is actively contributing to this field, proposing new methods, architectures and implementing applications that make this technology a reality

Abstract: Wireless sensor networks (WSNs) represent a newparadigm in the way to take measures from the environment. AWSN is a set of nodes deployed in a specific area to measurephysical parameters and actuate if necessary.

In this PhD work, a new HW platform for the nodes ispresented. Its main feature is modularity, which gives hugeflexibility, allowing redesigning in a faster way than usual.Different layers can be interchanged in order to fulfill newapplication requirements. Therefore time to market can beremarkable reduced.

In the other side, not only flexibility in the node is required,but in the way to communicate to sensors and actuators. In thiscontext, a library of analog and digital interface transducershas been developed, and intensive research has been carriedout to provide universal communication between the nodes andthe transducers.

Thank you for reading this third issue of CEI-UPM Newsletter. Our aim is to continue providing information on our activities, results, news,… and some gossip, which is

always welcome .

In this issue of CEI-UPM newsletter, we would like to show our activity during one year, starting on July 2010. We know that we are a bit late on this issue, but time is shorter than we think and our duties

are too many!. Our editorial line, is based on the team work. The statement selected for this third number states what is essential in a research environment, the coordinated team work. The three main

research lines at CEI-UPM work together in projects, share resources and space. Due to this sinergy, we can face projects that involve two or more fields and we can optimize the use of common resources.

Examples like the experience in digital control of power converters, based on FPGAs or DSPs, is difficult to make in an isolated way. Another example is a project related with metering electrical power

connected to wireless sensor networks, as a result of the cooperation of the embedded systems group and the power quality researchers.

In this issue you will find an intersting quiz: the electronic sudoku… but you can do it in paper! There is also an interesting article about the use of simulation tools in power electronics, written by our

colleague Prof. Roberto Prieto, who has made a number of contributions to this field.

Preparing this Newsletter regularly is not an easy task, but thanks to the contribution of many CEI-UPM members, we are being able to complete our duties.We really appreciate if you send us any

suggestion, question or comment to cei@upm.es. Enjoy reading this Newsletter!… and more will come in a few months! The editorial board

Unlike the integrated digital circuit designer, who has always rested in the simulation tools as a necessary design procedure, the designer of power electronic circuits has traditionally been

based on trial and error procedures for the final stages of the design. However, this trend has changed dramatically over the past 20 years, in which the power of the computers and the

CAD tools have evolved tremendously.

Many power electronic circuits include devices that work as switches that switch at high frequency (hundreds of kilohertz). For this reason there have always been several specific

difficulties for the simulation of these circuits. One of them is a common problem to all simulation tools, which is the availability of models that provide the expected information of the simulation. It is

important that the model is accurate enough to be useful without increasing its complexity more than necessary, since this implies simulation time problems or potential problems of convergence. Another

problem associated with these circuits is the fact that they commonly work with waveforms presenting high derivatives and high frequencies. In addition to that, there are several orders of magnitude of

difference among the temporal parameters involved in the simulation: the transitions of the voltage and current are commonly in the range of nano-seconds, the switching period is in the order of micro-

seconds and the quasi-static evolution of the signals is in the order of mili-seconds. All these facts increase the difficulties in model convergence.

Many of the difficulties discussed above have been solved today in several simulation systems which have large libraries of models and include robust mathematical algorithms solving potential problems

of convergence. However, a new challenge has appeared in the current scenario that is the simulation of large electronic systems against the simulation of a single circuit. This new situation makes

necessary the development of new models of the components that enable system-level results, eliminating the information with not useful contribution to the analysis. For example, the system designer

may be interested in information on the overall performance, power budget, stability or the impact of failures in the system but will not be interested on the current ripples in the devices. Therefore, the

models and how to implement them should be different depending on the level of abstraction and the information that is necessary from the analysis.

The Center of Electronics for the Industry (CEI) has worked for over 15 years in the development of models and circuit simulation tools for power electronics. Within the work done in the field of design

and modeling of devices it is necessary to emphasize the commercial tool "PExprt" which has been fully developed in the CEI and is marketed worldwide by the American company ANSYS. This tool

which has sold more than 300 licenses to over 250 customers, is a reference in creating designs and models of magnetic components for power electronic circuits. In addition, the CEI has developed

component libraries as "SMPS Library", which is also being marketed by the same company, brings to the designer of power electronic circuits a collection of component models to simulate these circuits.

In the field of system design, the CEI has developed the "SMPS parametrization Tool", which is a tool sold with the "SMPS Library" that provides behavioral "black box" models of DC/DC switch mode

power supplies for its use in the simulation of complex power electronics systems.

The CEI was officially recognized as a "UPM Center" in October 2006. When we were discussing the key factors that would add value over the existing DIE (División de Ingeniería Electrónica), the leader of a well established International Center, one of our references along the years, told us "You already have a Center". The formal recognition is important, but the daily work and the activities carried out by a number of researchers and staff aligned towards some common objectives, sharing a joint strategy along the years, is what really produces results and adds value to the community. We pursued strong and stable links with industry, we focused on integrating persons with diverse origin and nationality, and generated some instruments that would help the task: the "Annual Meeting", the "Newsletter“ or the "Monday seminars" are some examples.

All this was implemented by team work, but special recognition is due to those who take the lead to move from ideas to facts. Teresa, Oscar and Rafael, we all are thankful for your work. We have improved significantly during these four years, and you keep on board for continuing growth. Thanks!

FIFTH edition of our Annual Seminar, we are proud to announce this event. It is a reality, gaining momentum yearly. Last year 31 attendees form industry represented 18 companies. 23 attendees from universities other than UPM, together with 46 CEI members, created an authentic collaborative atmosphere to share results and envisage the future. Aiming at being open, in this edition the technical sessions include specific spots for industry and cooperating universities. We have also prepared a conversational discussion on "Entrepreneurship in Electronics", to stimulate new ideas and paths to produce value out of the daily research work.

"Energy" and "Sensing the world" are two megatrends that may benefit from our research on Electronics. We are enthusiastically working on sensor networks, reconfigurability, embedded control systems, energy efficiency, power quality, power management, on chip power conversion, RF amplifiers, modeling, control and optimization of power architectures, wide bandgap devices and photovoltaic inverters. We are also eager to learn about graphene, spintronics, or any emerging technology. We count on you for continuously focus our joint research. Thanks!.!

Would you like to see the atomic structure of a bone? Or would you like to film a chemical reaction? Or would you like to see the performance of materials in structures smaller than 100nm? These type of experiments will be possible in the near future thanks to the European XFEL. The X-Ray Free Electron Laser is a 3km long facility that is being built near Hamburg. Twelve countries, lead by Germany, are collaborating to create this unique best-in-the-world scientific site. Hopefully, it will be ready in 2015. Spain is participating with 2% of the total budget, mainly through In-Kind Contributions.

To produce an X-ray beam, bunches of electrons are accelerated in resonators and then driven into a slalom-type path created by undulators, to emit a high quality X-ray radiation whose wavelength can be as small as 0.05nm. The control of the electrons beam, in both resonators and undulators, is carried out by super-conductive magnets. UPM-CEI is participating in this outstanding project being responsible of the power supplies of the cold magnets of the facility. This is a special power supply that should be very accurate in controlling its high output current, especially when the magnet is in super-conductive mode and no power is delivered to it. A mixed control mode varying both duty cycle and frequency has been adopted. The power supply is remote controlled and special attention has been paid to obtain a high reliability, introducing redundancy and some protections. We are very proud of adding our knowledge to this initiative that may lead to achieve important physics discoveries in the future.

• Spanish research team comprising José A. Cobos, Oscar García, Roberto Prieto, Pedro Alou, Jesús A. Oliver and Miroslav Vasić from CEI, have been awarded the SEMIKRON Innovation Award for their concept “RF Power Amplifier with Increased Efficiency and Bandwidth”. These awards, presented at this year’s PCIM Europe in Nuremberg, are awarded by the SEMIKRON Foundation and the European Center for Power Electronics (ECPE) for excellent projects, products and services and innovative concepts in the field of power electronics (May 2012).

We are living a long lasting economic crisis, so it is time to work harder and better. Everyone can do a lot, pushing in the appropriate direction. Our mission as an Engineering Research Center is to help engineers and industry to be more prepared, and to increase activities that create value.

Any research Center needs to handle money to keep things running, in many cases "seed" money, to launch and perform new research lines or to proof new concepts that will be converted into new products by companies later on. Creating value for industry is part of our mission. But research in university also needs the freedom and creativity that only "long term" planning may produce.

At CEI, we are very active, working in many projects. Since National funding is decreasing, we are more active in European Programs and even use our own resources, obtained in other projects with industry. Our research activity increased 2.5x in the last 3 years. Around 70 persons work hard every day to create value, in a seamless integration of young research students with experienced Doctors and Professors, being the full time Master and Doctoral students the core of the group. A special recognition to all, researchers, technicians and administration.

We are optimistic because young engineers and international students join us everyday, and new projects start. Four new projects just started, with both public (DREAMS and POWERSWIPE) and private funding (we thank BOSCH and FIDELIA GROUP, and hope to have a fruitful and long-lasting relationship with them).

The UPM Radio Engineering Group (GIRA) has also joined CEI, being effective July 2012. This complementary expertise is fundamental for industrial electronics education and research.

We also welcome Javier Uceda. His contributions as President of the University in the last 8 years have been outstanding. Now he is full time at CEI. This is added value for the Center. Our vision will strengthen, new horizons will come closer, and we will do more, and better.

Our wish is "keep going, keep investing in research"! The editorial board

the fifth Annual Meeting of the CEI-UPM, that took place in the ETSII- UPM on March 22nd and 23rd, 2012. The Poster and Technical Sessions showed current research, including: Control Techniques, Modeling and Simulation, Optimization of Power Circuits, Power Topologies, Re-configurability & Evolvable Hardware, Wireless Sensor Networks

March 22nd, in the afternoon

In this Edition, the opening ceremony was led by the ViceDirector of research from the E.T.S.I. Indutriales (UPM) and the Director of CEI. An overview of the history of CEI and the motivation to organize the annual meeting was given. It was devoted to show what we do at CEI, and to foster cooperation and research alignment with industry and other universities

After that, a Conversational Discussion called,

Entrepreneurship in Electronics, from ideas to facts, how to face challenges in electronics spin-offs?

was carried out. Four relevant participants shared with us their own experience: Juan B. Genua from LUIX (San Sebastian-Spain), Juan M. Carrasco form Green Power (Sevilla-Spain), Luis Redondo form INETSIS (Madrid-Spain) and Pedro Moneo from OPINNO (San Francisco-USA). Their complementary points of view, their past experience, their expectations and their challenges helped us to know about entrepreneurship in a wide range area of electronic applications.

March 23rd, in the morning

The Friday technical sessions were structured in three parts: CEI, University and Industry sessions. For the CEI oral sessions, some of the key contributions of our Center were selected, covering several topics of our research lines. In this edition, contributions of four outstanding groups of several Spanish universities were received. We appreciate very much presentations from U. Carlos III, U. de Las Palmas de Gran Canaria, U. de Zaragoza and U. Politecnica de Catalunya. Finally, in the industry session, four of our associated companies showed us some of the challenges they were facing. Special thanks to Thales Alenia Space, Intel, CRISA and Enpirion and the speakers for their willingness to collaborate.

Social event After one day and a half, the relaxing cocktail was a very nice chance to discuss and to share opinions while enjoying and tasting some appetizers and, surely, to wish a very warm see you next year at the 6th CEI Annual Meeting

• We would like to give a very warm welcome to Javier Uceda. After many years of service to the University in the most important management positions (Vice-director & Director of ETSII, Vice-president & President of the UPM), he has recently finished his 8 years term as President of the UPM. We are happy to count on him, full-time, again.CEI will take advantage of his vast

The term Industrial Electronics is one of the widest we may find in the electronic field. It covers more than we could expect at a first glance. Traditional approaches identified Industrial Electronics with everything that had a relation with power electronics, power drivers and controllers, etc. During the last ten years, we have seen how this traditional approach was overcome by other aspects related with sensors and actuators, digital systems and networked elements. Nowadays, we can find more than seven different (very different!) tracks in specialized conferences like IECON (the major event of the IEEE Industrial Electronics Society) covering many different fields from very large installations to tiny elements needed to solve complex problems, from practical and challenging applications to modeling and simulation tools.

POWER SoC With Integrated PassivEs (PoweRswipe) funded by European Comission FP7 01/10/2012 to 30/9/2015

Summary.- The PowerSwipe project will address thea key technologies for PowerSoC by, for the first time, miniaturising and integrating state-of-the-art, high density trench capacitor substrate

Starting Cryogenic Analysis, (CRYOSTART) funded by Fidelia Group, 1/6/2012 to 31/5/2013. Summary.- The main objective of this project is to design and develop the necessary electronic equipment to apply electric and / or magnetic fields of the appropriate intensity and frequency to achieve the supercooling of water, so that ice crystals are not formed even lowering its temperature far below 0ºC. One of the expected applications of this technique is to enable the conservation of all types of body tissues, including organs for transplants. Nowadays, there is a tight time limitation (few hours) between donation and implantation. The organs cannot be frozen because ice crystals damage the cells. If a bank of organs were available, more people could be saved.

Following this stream, CEI-UPM (formerly UPMDIE) started some research lines related with embedded systems some decades ago. Starting in fields devoted to ASIC design, mainly for control applications, and following with the design and the tools related with complete systems, to nowadays activities that are focused to reconfigurable hardware, wireless sensor networks, embedded intelligence. All these activities are supported by the interest of industries and companies (both technology providers and final users) as well as the public authorities through their research programs (FP7, ARTEMIS, Plan Nacional, etc.). Among all the different technologies, techniques and applications, I would like to highlight some of the opportunities that start to open in front of us, and that CEI-UPM is addressing as some challenges of our activity. The use of reconfigurable hardware is opening the possibility of doing self-healing circuits, capable of doing self-reconfiguration of their internal structure in real time, when they detect a failure or a mis-functioning in its behavior. Applications in critical or unattended systems may be the key for having these elements in real industrial products. The use of massive number of interconnected elements, in a seamless way, with no network infrastructure and with additional sensing capabilities, may be the real starting point of cooperating objects, allowing the deployment of wireless sensor networks in critical scenarios, industrial places or even in smart cities, to measure and monitor the environment and even to improve it. At last, but not least, new human-machine interfaces, innovative uses of technology, may put embedded systems closer to final users, and therefore is not only a question of the internal structure of these embedded systems, but also, the external elements that allow their practical use. The projects that are currently being held at CEI-UPM in the embedded systems area, show many of these techniques and applications: environmental monitoring, energy efficiency in lamps, energy metering, context-aware multimedia systems, self-awareness in hardware structures, enhanced security in networks, efficient planning of WSN scenarios, interactive systems, are some of a larger list of the examples that are currently being run in our research center.

• Outgoing visiting researchers during this period

This year for the first time in two decades, our speciality has been the most demanded by the undergraduate students. The reason might be that now we teach "Fundamental electronics" before they take the decision. We opened the lab for them, our faculty, researchers and students dedicated extra time to teach and initiate them in electronics, and they liked it. When you dedicate time and effort to people, it flourishes.

We like thinking out of the box. Electronics applied to whatever may benefit: Industry, Energy, Communications, Mobility, Health,... wherever we may help, we try, and we are supportive. Count on us!

On the personal side, we wish the very best to Roberto Prieto. His new role as VicePresident for Research at UPM is not only a recognition for his continued hard work, but an opportunity to push further research initiatives at University level. We are confident his background at CEI will be very helpful, and he will have our continuous support. Congratulations, and good luck

The editorial board

CEI is full, and we like it.

A large room full of young people, researching in different fields around electronics. It is challenging and appealing. It attracts more people. There are many causes for this. Some are major, some minor, but all count. It is the sum of everyday efforts and decisions, by all of us.

We know there are many possible indicators. We are used to external quantification, parametrization and rankings: number of projects, master & doctoral dissertations, publications in indexed journals, papers presented at conferences, etc. Easy to calculate. However, the indicator that integrates all the other, and it is the reason why we are productive is the "atmosphere in the lab". Many people working, every day, in research, that is what we value, and what we care and protect.

Some of the more advanced techniques used in the biomedical field require the knowledge and experience available at CEI. Due to this reason, CEI is giving some steps to extend its activities in biomedical applications. Some years ago we developed, at the beginning for “Philips Hearing Implants” and later on for “Cochlear” the contactless supply of their cochlear implants. Our background on high frequency power conversion and modelling of magnetic components helped us to improve autonomy by more than 20%. Last year we started a new activity to apply specific electric and magnetic fields to achieve water supercooling. Applications are mainly in the field of CAS (Cell Alive Systems): preserve food, tissues, and in the long term, even organs.

Recently, in close cooperation with the UPM Centre for Biomedical Technology (CTB), researchers at CEI have begun to work in new areas linked to health care and biomedical applications. In particular, the use of magnetic nanoparticles hyperthermia to damage cancerous cells is one example where our experience in the modelling of complex electromagnetic fields could be applied. At the same time, we are cooperating in the development of the power supply to generate the current waveform able to produce the desired magnetic field in a coil. CEI is also using its experience in radio signals and 3D reconstruction of scenarios in a new cooperation with the bio-electromagnetism group. The aim is to develop new ways of representing the information of electromagnetic radiation supported by citizens to study the potential damage of large doses of RF signals in human health. Some electronic systems related with these measurement systems will be developed by CEI. These examples show some of the emerging areas in the biomedical field where the CEI researchers can extend their activities. At the same time we have a very small experience and knowledge in the core of the biomedical field, and consequently we need to work side by side with other specialists creating multi-disciplinary research groups.

On March 14th and 15th, 2013, we celebrated the sixth Annual Meeting of the CEI-UPM at the ETSII-UPM. As in previous editions, the Poster and Technical Sessions showed current research, including: Communications applications, Control Techniques, Modeling, Simulation and Optimization of Power Circuits, Power Topologies, Re-configurability & Evolvable Hardware, Specific applications and Wireless Sensor Networks. In this Edition, the opening ceremony, March 14th, in the afternoon, was chaired by the UPM VicePresident for research, the Director of the ETSII-UPM and the Director of CEI. An overview of the CEI strategic research lines was given. As usual, it was devoted to show what we do at CEI, and to foster cooperation and research alignment with industry and other universities. The Plenary talks on “Cutting-edge technologies for the 2020 horizon”, were chaired by Prof. Javier Uceda. The first speaker was Professor Javier de Felipe from the Laboratorio Cajal de Circuitos Corticales (CTB-UPM), who talked to us about “A new strategy to study the brains: The Human Brain project”. Prof. Francisco Guinea from the Instituto de Ciencia de Materiales de Madrid (CSIC) presented “Graphene: challenges and opportunities”. Speakers shared a great and fruitful discussion with the audience. The traditionally Poster Session was held in our lab. Our young researches had the opportunity to show their research work and to discuss about their latest outcome. Friday (March 15th) was structured in two oral sessions, chaired by P. Alou, E. de la Torre, F. Moreno and J.A. Oliver, where some selected key contributions from our main research lines were presented. We enjoyed very much presentations from AIRBUS, INDRA, UTRC (Ireland) and FIDELIA GROUP, showing some of their most recent work and even some of the challenges they are facing. After one day and a half of profound interaction, cocktail was a very nice chance to relax and make plans for the future while enjoying and tasting some appetizers and, surely, to wish a very warm “see you next year” at the 7th CEI Annual Meeting

First of all, we wish to express our gratitude to ETSII, for being sensitive to our need of additional laboratory space. Research activities at CEI will benefit from this enhancement, and we will devote our best to use it efficiently. We also appreciate ETSII support in the organization of SAAEI, which was successfully organized by CEI at ETSII, as described below. The school was the venue of an interesting conference on Industrial Electronics, where over 100 researchers presented their activities, discussed about the future, and participated in a competition on wireless energy transfer.

Regarding strategy and future directions, our master on Industrial Electronics is key. It is one of the main research gates to enter CEI. Spanish and International students enroll in this research adventure, which is usually extended to pursue the Doctoral degree. The courses and educational program are mainly oriented to fundamental and applied research on Industrial Electronics, and are the basis for the Doctoral program. It is time now to expand the scope of the master, to facilitate the admission of the new graduates under the Bologna declaration. And it is important to offer our master students new opportunities: either continuing the Doctoral Program, or joining Industry. A new structure and contents will be envisaged, clearly connected and committed with Industry research needs.

Francisco Núñez de Celis decided to retire this year. Although not involved in CEI activities, he has been a faculty member in our Department for over 30 years. We recognize his work and dedication, and wish him the very best. Last but not least: we have decided the preliminary dates for our annual event. The Annual Meeting of the Center for Industrial Electronics will be held during March 27th & 28th. Thursday and Friday, as usual, to facilitate traveling. Please take note of the dates!!!

Embedded Intelligence on chip, a research challenge

by F. MORENO

January-June 2013

Nowadays, hardware embedded systems must perform progressively more complex functions, which requires a high level of embedded intelligence in hardware. This rise in intelligence forces a rise in the level of information processing that the hardware embedded systems carry out. This, in turn, gives rise to a significant increase in complexity of the hardware and the software. Due to this, the conception and design of those systems has to face two major points, in many cases opposed to each other. On one side, a higher level of intelligence is demanded day by day to the systems, and, on the other side, those systems have requirements of real-time operation and reliability difficult to meet in complex systems. Facing that research challenge, CEI-UPM is getting on its own research lines related to.

The use of reconfigurable hardware is one of the most popular approaches for tackling that motivating challenge. Although reconfigurable hardware based on FPGA reconfigurable architecture is a little bit limited in terms of algorithm complexity, it is one of the most promising research lines at CEI. Other possible solution is to design and to implement evolvable hardware architectures which is also an interesting research approach, even though they are highly hardware resources demanding as their main drawback; we envisage those architectures as a valuable alternative. Cognitive architectures capable of operating with abstract variables, reacting to multiple kinds of perturbations and to the uncertainty of the environment which may reach very high levels of complexity are being a very promising approach to be implemented on FPGAs. However, the limited resources available in hardware embedded systems and the standards of reliability required, make that these types of architectures were intelligence limited; although some qualities of complex cognitive architectures in terms of intelligence could be grounded in embedded systems, in spite of resource limitations. Today at CEI-UPM, that is one of our most motivating challenges for the near future

Convertidores de Alta VElocidad de conmutación multinivel y multifase para aplicaciones espaciales (CAVE) , funded by Mº de Economía y Competitividad, 1/1/2013 to 31/12/2016. The aim is to design and build new high efficiency, wideband, lineal power amplifiers for space applicattions, built with Gallium Nitride semiconductor technology for space applications. They will be able to replace the conventional low efficiency power amplification stages used in nowadays communicattion satellites. To achieve this objective, these technologies will be explored: RF and microwave high efficiency wideband power amplifiers; linearization techniques for high efficiency power amplifiers based on Envelope Tracking (ET); high switching speed power converters for envelope amplifiers based on multi-phase and multi-level technology; and new Gallium Nitride wide gap semiconductors both for RF and Microwave applications and power electronics applications.
