What is different between Electronic load and LED emulator?Ordinary electronic load are designed to be used for constant voltage sources thus the response of CC mode is fast but slow in CV mode. As contrary, the output of LED drivers is in CC mode thus high speed CV operation and CR mode are necessary. The LED emulator realized such characteristics intended to test LED derivers.

Switching power supplies are widely used in various equipment and ex-pected to world properly and reliably. The failure of switching power sup-ply will result serious damage to the whole system . For sever applica-tions, it is recommended to test and measure the Ripple & Noise of such switching power supply periodically . Such as power plant and aircraft maintenance, they are required to replace certain parts such as electro-lytic capacitors periodically before the end of its life time.

Ripple & Noise Measurement of Switching Regulator (SMPS)

Nov. 25, 2009

It is needless to mention that almost all of electronic instruments and OA equipment are equipped with switching regulator inside as a power device. The product which runs on AC100V or 200V are incorporated with AC/DC converter and Note-PC so forth which runs on battery are incorporated with DC/DC converter. The DC output of either AC/Dc or DC/DC converter contains certain amount of ripple & noise component on it. To measure this ripple & noise level is one of important factor.

Switching regulator

Ripple & Noise waveform Purpose of ripple & noise measurement The level of ripple & noise is representing one aspect of switching regulator performance and also used to estimate remaining life time of the regulator. From this context, the ripple & noise level is measured in addition to the output volt-age at the maintenance depot. As the ripple & noise level is heavily in relevant to the component such as electrolytic capacitor that has certain life time. Measuring the ripple & noise properly gives good estimation of its life.

How to Measure Ripple & Noise?As it called ripple & noise, it’s a collective various wave-forms so the accurate measurement is somewhat difficult. It can be measured by oscilloscope but it will require high degree of measuring technique as ripple & noise waveforms has to be pulled out from the collective waveform. This will result dependency who is measuring and their experience. With using ripple & noise meter, there is no reading error or no special technique required. The ripple & noise meter pull out the ripple and noise voltage from the collective compli-cated waveform and display it in digital. As for the measurement method of ripple & noise, JEITA (Japan Electronics and Information Technology Industries Association) standardized as RC-9131B.

Ripple & Noise meterRM-103

The differential probe (DP-100A) x 1 comes with standard accessory. With ripple & noise scanner, it can measure 8 to 16 channels suitable for multi-channel automatic meas-urement system.

When in Load Regulation test, normally electronic load is used. But it limits the test within the features equipped in the electronic load. When our Electronic load is used, it can emulate real loading current when connected a function generator to external input of the electronic load. This is extremely suitable to test such as current waveform of motor used in a electronic vehicle.

Please consult us, we produce software to your need on LabVIEW of national Instruments.

Function generator alone can generate various waveforms and provided sequence function. With Arbitrarily waveform software, much wider range of flexibility is obtained.

Connect function generator output to EXT. input of elec-tronic load as waveform A and waveform B. The electronic load may be responded in accordance to the output waveform of the function generator. With this function, electronic load can emulate various loading conditions.

Best solution for Battery ECU Testing

The Electronic Control Unit (ECU) is widely used in vehicles including EV (Electric Vehicle) and HEV (Hybrid Electric Vehicle). The Battery ECU is built intended to monitor each battery cell hence there are many measurement inputs. This makes it is much troublesome to test Battery ECU itself. The Mul-tichannel Battery Emulator can test such Battery ECU. Multichannel Charge & Discharge Tester, the MCD series can be used as a very efficient Battery Emulator.
