There has been an ever-increasing demand to increase the switching frequency, power density, efficiency and dynamic performance of switch-mode power converter, the development of soft-switching technology has taken an accelerated pace. This paper provides a review on the development of soft-switching power converters for electric vehicle (EV) propulsion and recent research trends will also be discussed, with emphasis on soft-switching converters for dc motor drives, soft-switching inverters for ac motor drives and soft-switching converters for switched reluctance motor (SRM) drives.
