Abstract	In this paper, we propose a single-phase single-stage hybrid AC/DC converter that can regulate the output voltage and improve the input power factor through phase shift modulation (D) at a constant switching frequency for wireless power transfer. In the proposed single stage AC/DC converter, formula to calculate the input power factor (PF) and the total harmonic distortion (THDi), and the voltage gain characteristics of CLLC resonant circuit for WPT are analyzed and presented. Also, the performance of the proposed single stage AC/DC converter was verified on a 1 kW prototype operating with an ac line voltage (220Vrms) and an output voltage (Vo) that varies between 250VDC and 350VDC.
