Resonant Fly-back Converter for Direct-Current Distribution

직류배전을 위한 공진형 플라이백 컨버터

This paper describes a resonant fly-back converter for high-voltage de distribution system. The proposed converter operates to change high-voltage de into low-voltage de with isolation and large converting ratio. The converter has a thyristor switch with an LC resonant circuit for commutation in the primary side of the gap transformer. The operation of the proposed system was verified through computer simulations and hardware scaled-model tests. The proposed system can be implemented with commercially available components and proven technologies.
