Abstract

This paper presents a single switch single power conversion (S3PC) Isolated AC/DC converter. With only a single switch, the S3PC converter performs bidirectional core excitation for the transformer by using series resonance so that the S3PC converter obtains high power capability (> 1 kW). The series resonant circuit also enables zero-current switching of the output diodes, thus reducing the reverse-recovery loss. Because the proposed converter has only a single switch and single power-conversion stage, the proposed converter has high efficiency and simple circuit structure. The design procedure and analysis of the S3PC converter are presented in detail. The effectiveness of the S3PC converter is demonstrated on a 1.5-kW/400-V prototype designed for test purposes.
