提出了一种用于电动汽车充电器的单级高频链软开关三相AC-DC变换器。该变换器的特点是基于升压全桥（BFB）拓扑的相位模块，用于三相工频交流（UFAC）到单相高频交流（HFAC）的转换，而不需要平滑直流链路，这为电源带来了简单性、成本效益、模块化和高效率。通过一台3 kW-20 kHz的样机实验，研究了该变换器在典型蓄电池充电模式下的实用效果，并从实用角度对单级变频、功率因数校正（PFC）和零电压软开关（ZVS）进行了评价。
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 3kW-20kHz 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.
