Abstract: Integrating the electric vehicle into grid or microgrid has been receiving more and more attention in recent years. Typically, the electric vehicle (EV) chargers with their power batteries have been developed for vehicle-to-home(V2H) applications, acting as a backup generation to supply emergency power directly to a home. Traditional EV chargers in V2H applications mainly consist of DC/DC and DC/AC stages, which complicate the control algorithm and result in low conversion efficiency. In order to solve this problem, a novel EV charger is proposed for V2H applications. It can boost the battery voltage and output AC voltage with only one-stage power conversion. Also, the DC, 1-phase and 3-phase loads can be fed with the proposed single-stage EV charger. The system control strategy is also provided to deal with versatile load variations. Finally, the performance evaluation results verify the effectiveness of the proposed solution.
