An Integrated SRM Drive with Constant Current Constant Voltage Charging Capability for Electric Vehicle Application

Multiport converter based integrated AC charging for electric vehicle (EV) batteries is investigated in this paper. An EV with a Switched Reluctance (SR) drive is considered and the proposed control scheme achieves constant current and constant voltage (CCCV) charging of the on-board battery with the charging integrated SRM Drive. In addition, unity power factor on the AC side is achieved without using any additional circuitry. Operation and control design is presented in detail and simulations are shown to verify the control strategy and assess the performance of proposed scheme.
