Full-bridge converter for UPS with D
1.1
Overview
The full-bridge converter kit is a demo board for UPS applications. It contains two sections of half-bridge drivers
and power devices, as shown in Figure 1.

The demo board needs two power supplies to provide an input voltage and a bias voltage. The voltages of both
power supplies are typically 12 V, which can be changed based on an application. The outputs can be connected
to a transformer. In this user guide, a transformer is used to get an AC voltage of 220 V with the input voltage of
12 V. In order to power up the demo board, two synchronized PWM signals are needed to control switching of
four power MOSFETs.
