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.
