Abstract

This paper presents a new composite soft-switching configuration for single-phase inverters where power bridge leg modules are used. The presented configuration consists of only one inductor and one capacitor as well as two low-power-rated switches/diodes for full-bridge circuits. It can realize snubber functions and/or resonant zero-current switching at any load current for switches in power inverters with unipolar sinusoid pulsewidth modulation control. The idea presented here is that soft-switching processes at turn-on and -off for each active switch in inverters can be different. The detailed circuit operational processes, simulation waveforms, and experimental results are included.
