Abstract

This paper presents a three-phase current source PWM converter with a single resonant DC link snubber which can operate under zero current switching (ZCS) commutation. The operation principle of this soft-switching converter is based upon the current overlapping soft-commutation and the resonant snubber soft commutation. A new space current vector modulated control strategy of this converter is effectively implemented by applying the space vector pattern to minimize the operating number of auxiliary active switches under the resonant snubber soft commutation
