Power factor correction controllers are widely used in the battery chargers of Plug-in Hybrid Electric Vehicle, connecting the grid with charging system to reach power factor equal to 1. Increasing the operational efficiency of the PFC is the inward search. This paper presents a three-phase full-bridge PFC circuit with >;97% efficiency at 10kW. Comparison of different control algorithms with corresponding power loss calculations is pursued to optimize the system design. Experiments on two 208VAC/10kW PFC prototypes equipped with either fast reverse recovery diode or Silicon Carbide Schottky Diode respectively validated the effectiveness of the design.
