Abstract :
This paper presents a three phase current-fed space vector modulation converter with a single auxiliary active capacitor type resonant DC link snubber and commutation inductor which can operate under zero current switching (ZCS) commutation. The operating principle of this converter is based upon the current overlapping soft-commutation with 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
