This paper presents a new composite soft-switching configuration for single
-phase inverters where power bridge leg modules are used. The presented con
figuration consists of only one inductor and one capacitor as well as two l
ow-power-rated switches/diodes for full-bridge circuits. It can realize snu
bber functions and/or resonant zero current switching at any load current f
or snitches 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 snitch in inverters can be different. The detai
led circuit operational processes, simulation waveforms, and experimental r
esults are included.
