10kW rapid charger for electric vehicle with active power filter function

In this paper, the 10kW rapid charger is proposed with an additional function of Active Power Filter (APF). The system is composed of the three phase ac-dc PWM converter, isolated dc-dc converter and non-linear load circuit. The ac-dc PWM converter of this charging system is designed to perform charging function and APF function. And it operates charging and APF mode according to the state of load. In charging mode, the isolated dc-dc converter is performed to charge the battery through the Constant Current - Constant Voltage (CC-CV) control and the phase-shift method. However, it is maintained as the non operation (NOP) state during APF mode. To verify the performance of the proposed system, the simulation and experiment were carried out.
