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
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.

DC/AC inverter
9/66
General description
UM0527
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
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.

UM0527
The power supply unit provides two outputs used in UPS blocks: +15 V for most of the
analog circuits and +5 V for the microcontroller. The switching voltage converter was built in
step-down topology with an integrated regulator L5970. The microcontroller is supplied by
linear regulator +5 V U3 LD1086V50. The switching regulator is controlled by the
microcontroller ON / OFF signal and the BUTTON signal from the front panel ON/OFF
switch. Additional supply is switched on by optocoupler SFH620 powered from the mains.

The interface unit provides the connection from the UPS unit to the PC via RS, USB or joint
signals. The interface contains a USB to RS232 converter based on the microcontroller
ST72F623F2M1, in the SO20 package powered from the PC, with optoisolation barrier
(PC817B) and RS232 with optoisolation barrier (PC817B). The required voltage for the
RS232 circuits is realized by the voltage pump converter built with NE555. The interface unit
also contains an analog multi/demultiplexer M74HC4053 used to switch signals from the
USB and RS232 to the microcontroller.

Referring to Figure 10, the measurements are defined as follows:
1.1.13
a)
Output current. Input voltage measurement unit is built as a differential amplifier
with a 2.5 V offset (LM324). The output signal from the amplifier is connected to
the A/D converter in the microcontroller.
b)
Battery voltage. The input voltage phase unit works as a comparator (LM324) and
contains information about the sign of the input voltage waveform.
c)
Inverter output voltage. Output current unit is built as a differential amplifier with
2.5 V offset (LM324). The output signal from the amplifier is connected to the A/D
converter in the microcontroller.
d)

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
27/66
General description
UM0527
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.

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
29/66

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.
Table 12.

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:

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.

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).

In any steps the squared value of the output voltage accumulates. The
accumulated value is compared with the nominal RMS output constant, and if it is
greater, the SHD signal rises to H.

The accumulated value of the output voltage is cleared, the variable storing a step
