A Reduced Switch Multiport Converter Drive for Solar-assisted SRM EV with Integrated Driving and Charging Features

Electric Vehicles (EV) offer a strong prospect in achieving emission-free transport. A multiport converter (MPC) integrating Battery, PV power, switched reluctance motor (SRM) and Grid for integrated driving and charging functions is presented in this work. Two relays are incorporated for isolating the ports during various modes. By proper control, Battery and PV power drive the EV together as well as independently, leading to range extension of the EV. Battery is charged using on-board charger (OBC) at unity power factor (UPF) from grid or from PV at EV stand-still conditions. The operation under various modes is verified using simulations results.
