Integrated on-board battery charger (IOBC) improves the utilization of on-board components. In the meantime, it has great advantages in volume, weight and cost compared with independent charging and driving system. But in the previously proposed topology, the motor may generate torque during the charging process, or the rotor needs to rotate a certain angle before charging. In this paper, an innovative integrated onboard charger using a 3-phase T-type converter is proposed. The topology is capable of driving, battery charging and vehicle-to-grid (V2G) operation. Simulation results of driving and charging/V2G verify the feasibility of the above functions of the topology.
