Analysis and Design for a New ZVS DC–DC Converter With Active Clamping

A new zero voltage switching (ZVS) boost converter is presented in this paper. By using an auxiliary switch and a capacitor, ZVS for all switches is achieved with an auxiliary winding in one magnetic core. A small diode is added to eliminate the voltage ringing across the main rectifier diode. This clamping technique can also be utilized in other dc-dc converters, and a family of new ZVS dc-dc converter is derived. A prototype (500 W/193 kHz) is made to verify the theoretical analysis. The efficiency is higher than 94% at 90-V input at full load
