摘要
This study proposes a high efficient series resonant ac-dc converter. The proposed series resonant converter has a structure integrated with an ac chopper. The proposed converter provides turn-on with zero-voltage switching of all switches and performs direct power conversion without several power conversion processes. Therefore the proposed converter can achieve high efficiency by minimising losses during ac-dc power conversion. In addition, it achieves high power factor without an additional circuit. The concept and operation principle of the converter are analysed and verified. A 300 W prototype is implemented to show the performance of the proposed converter.
