Abstract

This paper presents a new isolated DC-DC power converter, named the double ZVS-PWM active-clamping forward converter, which operates without switching losses from no-load up to full-load. The proposed converter is based on two active-clamping forward converters, coupled with a single high frequency transformer. This converter is suitable for high input voltage and high power applications. Its operating principle, theoretical analysis, design example and experimental results, taken from a 3 kW laboratory prototype, are also presented
