Abstract

This paper presents a new prototype configuration of a single-phase voltage source soft switching inverter using IGBT power module packages in order to reduce switching power losses, electromagnetic noises. A single inductor-assisted resonant AC link snubber circuit as one of the resonant snubbers to achieve the zero voltage soft switching for the single-phase voltage source inverter is originally demonstrated, and its operation principle and unique features as well as the practical parameter design method of resonant AC link snubber circuit treated here is described on the basis of computer-aided simulation analysis. Furthermore, the practical operating performans of the single inductor-type resonant AC link snubber for the single-phase voltage source soft switching inverter using IGBTs are discussed and evaluated on the basis of switching power losses and electromagnetic conductive noise as compared with those of single-phase voltage source hard switching inverter from an experimental point of view.
