1.1 Hardware architecture
1.1.1 General realization
The UPS evaluation board is built in offline topology with AVR regulation of the mains boost and buck. The inverter module contains the push-pull DC/DC converter and the DC/AC output full-bridge generating quasi-sine waveform. The battery charger module is connected at the output of the UPS and it also has the function of taking over the reactive power which is present on the inverter during battery operation with reactive - resistive load.
The microcontroller controls all UPS functions. It monitors the mains parameters in order to ensure the proper level of the output voltage. The microcontroller measurement parameters are input/output mains voltage and phase, output inverter voltage, battery voltage, output current and output power. The UPS has a built-in RS232, joint signals and USB interfaces (USB for RS232 converter).

General description UM0527
8/66
The converter is based on push-pull topology. The PWM controller works in voltage mode. The power components used for the low voltage side are switches 5 - 8 and a transformer. The energy recovery circuit includes L1, D1, L2, D2, C1 and R1. It works as both a clamp and a snubber. Power components on the secondary side are limited to rectifier diodes D3 - D6 and a small voltage smoothing capacitor. The output voltage is limited with direct control loop without insulation. An internal soft-start circuit is used to limit the voltage rise rate on the output of the DC/AC converter. The soft-start circuit is controlled from the microcontroller by an additional transistor. The PWM controller is powered from the main UPS power supply section. The output converter voltage range is battery voltage dependent and has been set to achieve maximum efficiency.

General description UM0527
10/66
The DC/AC inverter was built in full-bridge topology. The output waveform is a quasi-sine waveform. The inverter is controlled by the microcontroller across two PWM drivers which switch four power transistors. The high-side driver parts are supplied with the bootstrap circuitry D1, C1 and D2, C2. The diodes D1 and D2 are high-voltage fast-recovery diodes. Switching off all transistors is achieved with driver internal logic if both INV_A and INV_B signals are set high or low. There is no any additional overcurrent protection for bridge transistors. Drivers are powered from the main UPS supply unit.

General description UM0527
14/66
The battery charger is used as a battery charger for the mains mode or as a reactive power recirculation circuit for the inverter mode. For both modes the charger output power is accepted by the battery. The charger power converter is built in quasi-resonant flyback mode based on the controller L6565 with external power switch Q1 and output diode D1. The PWM controller is powered from the main UPS supply module and from the auxiliary winding on the flyback transformer. The transformer is designed with the ETD29 core. The CHOFF signal is used to switch (Q2 and Q3 STP80PF55) charging modes by the microcontroller. An additional output voltage loop limits open output charger voltage. The charger module also contains a battery overvoltage protection circuit with SCR TYN608 and voltage reference TL431.

1.2 Software architecture
1.2.1 Data models
The setting of the UPS is stored in EEPROM memory. The data format is shown in Table 7:
1.2.2 Protocols
The SEC protocol is described briefly below. All messages sent between the PC and the UPS look like:
^<type><len><data>
where:
^ : the header character
<type>: the type of message being sent
The PC sends the following message types to the UPS:
– P: PC polls UPS (a query)
– S: PC sets UPS variable
The UPS returns the following message types to the PC:
– D: UPS returns data to PC (result of query)
– 0: UPS rejected command sent from PC
– 1: UPS accepted command sent from PC
<len>: 3 characters length of following data (zero padded decimal ASCII)
<data> - "len" characters of data
Commands are contained in the <data> field and are always 3 characters long. The orders supported are listed in Table 8.

1.2.4 Main loop
The UPS works in 7 modes:
– Inverter mode - if the mains voltage is lower than 167 VAC RMS(87 for US version) or higher than 286 VAC RMS(153 for US version) the inverter is switched on. At outputs INV_B and INV_A, a PWM signal 50 Hz (60 for US version) with 40% or less duty cycles (depends on DC/DC output voltage) is generated. In inverter mode the ACF signal is switched on. If the mains voltage returns to the correct value (167 - 286 VAC or 87 - 153 VAC for US version), the PWM signal is

synchronized with the mains, the ACF! signal is set to low and the inverter is switched off.
– Mains mode - in this mode the battery charger is switched on and the UPS is supplied from the mains. The inverter is switched off (INV_A and INV_B are in low state), and ACF! is high.
– Buck mode - in this mode the battery charger is switched on and the UPS is supplied from the mains. The ACH signal is switched on, the inverter is switched off, ACF! is high and the ACL signal is in low state.
– Boost mode - in this mode the battery charger is switched on and the UPS is supplied from the mains. The ACL signal is switched on, the inverter is switched off, ACF! is high and the ACH signal is in low state.
– Standby mode - in this mode the battery charger is switched off and the UPS is supplied from the battery. ACH and ACL are in low state, ACF! is low, CHOFF is high, and the inverter is switched off.
– Standby charge mode - the UPS is in this state when the mains is lower than the low level boost mode. ACH and ACL are in low state, ACF! is high, CHOFF is low, and the inverter is switched off.
– OFF mode - the UPS in this mode is totally switched off. This state is availably only in battery mode after pressing the on/off key longer than 4 seconds.
Additionally the UPS tests the battery. The battery test is done by switching to the inverter mode. During the test the MCU measures UPS output load and battery voltage. If the battery voltage during the test falls below the limit, the battery is failing. The value of the limit depends on time and load current. The test can be forced by the user with a PC. The battery condition can by checked after switching to the inverter mode without forcing the test. A load is necessary to test the battery.

1.2.5 ADC
The ADC thread measures values as described below:
Mains voltage - the voltage measured at INP_LEV is needed for calculating the following values:
– RMS - true RMS main voltage which determines the working mode of the UPS: mains mode, buck mode, boost mode or inverter mode. This value is calculated for one period of input voltage.
– SAMPLE - actual sample voltage which is the value needed for calculating RMS. Additionally this value is needed to compare with the predicted value of the mains
General description UM0527

value. The result of the comparison is used to make the decision to change the working mode from the mains to the inverter.
– Battery voltage - the value measured at AKK_LEV input determines the process of charging and discharging the battery. The value is averaged. During battery operation a signal is needed to indicate a low level of the battery or to protect the battery. In mains mode this value determines the charger's working mode.
In DC/DC converter voltage the value is not averaged and is used to check if “out” is in short-circuit state.
During load current the value is measured at PWR_LEV input. The value is needed for calculating the power of the load (RMS for one period), battery current, overloading.
1.2.6 Communication
The thread of communication is in charge of communication to the PC. This thread completes the packet from the PC and sends answers. Received packets are interpreted in the main loop.
1.2.7 SPI
SPI interface is using for communication to EEPROM memory. SPI needs four signals: MISO, MOSI, SCK and CS. In inactive state all signals are high.
1.2.8 Keyboard
The keyboard contains only one key button connected to BUTTON input active low. The reaction for this signal depends on the working mode:

Additionally the state of OUT_REL is stored in EEPROM memory and restored after a cold start independent of the AUTOSTART setting.
1.2.9 LEDs
LEDs indicates the state of the UPS. The active state is H.
1.2.10 Charger
The battery charger works in two steps: constant current charging and hysteresis constant voltage. In the constant current step, the battery is charging in current mode until the voltage of the battery is lower than 28.2 VDC. In the second step, the charger is switched on when the battery voltage is lower than 26.8 VDC and switched off if the value is higher than 27.8 VDC. The microcontroller controls the process by switching the CHOFF signal.

1.2.11 Inverter
The inverter is controlled by signals generated by the PWM module. In battery working mode the microcontroller generates two signals: INV_A and INV_B. The frequency depends on the firmware version: EU - 50 Hz, US - 60 Hz. The duty cycle is less than 50% and depends on the voltage of the DC/DC converter. The phase of the INV_B signal has to be shifted by a half time period to INV_A. The inverter is controlled by a timer interrupt. The frequency of the interrupt is 32 times higher than the mains frequency: every half-period is divided into 16 steps, and the number of steps is stored in a global variable.
Before any steps the SHD signals are checked and if they are inactive (H), the inverter signals are switched off (rise to H).
Buffered working mode< 26,8 L
