Abstract :
In order to reduce interference on the grid, a power factor correction (PFC) circuit used for electric vehicle (EV) wireless charging system is analyzed in this paper. Firstly, the load of PFC circuit is described considering current source type inverter and energy transfer coils. Then, dynamic model of boost converter used in PFC circuit is established through state space averaging method. Moreover, controllers are taken into count to get system close-loop transfer functions. Based on the system model, PFC circuit is studied under conditions of different charging powers, coil lateral misalignments and load inductances. All the simulation and experimental results have proved that the designed PFC circuit works well on the application of EV wireless charging system.
