摘要：
A single-stage high frequency-link soft-switching three-phase ac-dc converter for electric vehicles (EV) battery chargers is presented in this paper. The proposed converter is featured by a boost full-bridge (BFB) topology-based phase module for the three-phase utility frequency ac (UFAC) to single-phase high-frequency ac (HFAC) conversion without a smoothed dc link, which brings the simplicity, cost-effectiveness, modularity and high efficiency into the power supply. Practical effectiveness of the proposed converter is investigated by experiment of a 3 kW-20 kHz preliminary prototype for a typical battery charging mode, and the single-stage frequency conversion, power factor correction (PFC) and zero voltage soft-switching (ZVS) are evaluated from a practical point of view.
