Abstract

The use of either lossless snubber circuits and/or resonant zero voltage and zero current switching (ZVS and ZCS) techniques increases the efficiency of power converters and inverters, and reduces electromagnetic interference (EMI) and noise. This paper presents analysis and design of a composite soft switching configuration for single phase inverters where power bridge leg modules are used. The presented single phase inverter consists of only one inductor and one capacitor as well as two low power rated switches/diodes for full bridge circuits. It can realise snubber functions and resonant zero current switching at any load current for switches in power inverters. The simulation waveforms and experimental results are given
