Abstract

A novel zero voltage switching half bridge power converter is presented. This power converter achieves zero voltage switching of main switches and zero current switching of a secondary diode while maintaining low voltage stress of the main switches. High efficiency power conversion is realized at high frequency switching. A prototype of a low profile 50 W DC/DC power converter is designed for an input voltage of 200-400 V and an output of 12 V. High efficiency of 87-85% and small size of 86×41×10 mm³ are achieved at 500 kHz operation
