STEVAL-ISS001V1
The UPS was designed with RS-232 joint signal
and USB interfaces (USB for RS-232 converter). It
is possible to connect the UPS to a PC using an
RS-232 or USB cable and control the UPS status
through the "UPS Monitor 3.0x" software that
must be installed on the same PC.
Description
This UPS reference design was built employing
off-line topology with AVR boost and buck
regulation of the mains. The inverter module
contains the push-pull DC-DC converter and the
DC-AC output full bridge generating a quasi-sine
waveform.
A microcontroller controls all UPS functions. It
monitors the mains parameters (input/output
mains voltage and phase, output inverter voltage,
battery voltage, output current and output power)
in order to ensure the proper level of the output
voltage.
