Abstract

The 25 kHz 20 kW AC/DC converter has been developed for high-voltage power supplies. The converter is designed with a series resonant H-bridge topology. PWM phase shifted control for power switches based on IC UCC3895 makes available high efficiency and noiseless performance of the power supply. In this converter electrolytic capacitors are absent in the high power circuit
