Abstract :
We present a 3.3kW on-vehicle battery charger (OBC) for plug-in hybrid electrical vehicles and battery electric vehicles. The OBC is developed with a semi-bridgeless front-end PFC boost converter followed by a ZVS full bridge DC-DC converter. The performance of the PFC boost is analyzed and measured using different switching power devices. The test data is measured in the same system, at the same points of operation, using the conventional Si SJMOSFETs and Silicon Carbide (SiC) DMOSFETs. With the SiC DMOSFET at 200kHz switching frequency, the measured maximum power conversion efficiency of the PFC boost front-end converter is 97.7%. The full OBC efficiency is 94.7%.
