Abstract: A High Efficiency Double–Stage AC-DC Converter is introduced and simulated, which can be used in Vehicle charging application. Front–end Converter is a half-bridge Zero Voltage Switching (ZVS) AC-DC with Power Factor Correction (PFC) topology. For improved efficiency and reduction of stress SiC MOSFET could be used and also high frequency switching could be possible thus by reducing conduction and switching losses. The Second-stage is a LLC resonant DC-DC Converter that help in achieving ZVS. The proposed topology is verified by simulating the model in MATLAB.
