Abstract

The on-board charger (OBC) of an electric vehicle (EV) is desired to perform many functions, such as transferring power from the grid to the vehicle (G2V), transferring power from the vehicle to the grid (V2G), and so on. To meet these requirements, a topology based on a four-switch three-port converter is proposed in this paper. In addition to the G2V and V2G functions, the proposed converter can transfer power from the high-voltage battery to the auxiliary low-voltage battery (H2L). Compared to the traditional OBC topology, the proposed circuit has a lower number of switches, reducing the cost of the system. Simulation results using PLECS software to demonstrate the effectiveness of the proposed topology.
