Abstract

The use of either lossless snubbers or resonant zero voltage switching (ZVS) and zero current switching (ZCS) techniques increases the efficiency and reduces the electromagnetic interference (EMI) and noise of industrial power equipment at high switching frequencies. This paper presents a new composite soft switching configuration which combines snubber functions and resonant ZCS circuits for switches in high power inverters. Simulation and experimental results are given
