Although three-phase integrated onboard chargers for electric vehicles (EVs) are important for high-power fast battery charging, the single-phase battery charging is still highly demanded in the consumer markets. The single-phase charging provides EV owners the ability to conveniently charge their vehicles through standard single-phase power outlets. In this paper, the single-phase charging operation of a three-phase integrated onboard charger is investigated. The single-phase charging operation can be achieved without any hardware modification to a three-phase integrated onboard charger. The circuit topology, operation modes, control strategy, and controller design for the single-phase operation are presented in detail. A three-phase integrated onboard charger designed by the authors is operated and tested as a single-phase charger with up to 1.6kW output power. Experimental results show that unity power factor (PF) can be achieved with a peak efficiency of 93.7%.
