This paper introduces a novel three-phase buck-type unity power factor rectifier appropriate for high power Electric Vehicle battery charging mains interfaces。The characteristics of the converter, named the SWISS Rectifier,including the principle of operation, modulation strategy,suitable control structure,and dimensioning equations are described in detail。Additionally,the proposed rectifier is compared to a conventional 6-switch buck-type ac-dc power conversion。 According to the results,the SWISS Rectifier is the topology of choice for a buck-type PFC. Finally, the feasibility of the SWISSRectifier concept for buck-type rectifier applications is demonstrated by means of a hardware prototype。
