UPS evaluation board
Introduction
The UPS evaluation board provides a complete solution addressing the low/medium range
UPS segment with 700 VA output power capability. The evaluation board, from a hardware
and firmware point of view, is ready to support the development of a complete solution.
Thanks to the PC software it's possible to monitor all the relevant system parameters using
the RS232 interface or the USB. The evaluation board is available for the 120 Vac market
and 230 Vac market.
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.
