摘　　要：为了减少混合动力电动汽车(HEV)接入电网充电时向电网注入谐波,车载充电机必须进行功率因数校正(PFC)。目前常用的PFC电路是单相不控整流+Boost两级电路,限制了变换器效率的提高。研究设计了一种交错并联Boost电路作为PFC电路。为了进一步提高效率,采用移相全桥ZVS DC/DC作为车载充电机的后级电路。在对上述的主电路拓扑的工作原理进行分析的基础上,给出了部分关键参数的设计方法,并分别设计了相应的控制策略。仿真和实验结果验证了所设计的新型车载充电机的可行性。In order to reduce the harmonics injected into the grid when HEV is connected to the grid for charging,the vehicle charger must carry on the power factor correction（PFC）. Single-phase uncontrollable rectifier with Boost circuit is the most commonly used PFC circuit,which can limit the converter efficiently. An interleaved Boost circuit is designed as PFC circuit. The phase-shifted full-bridge ZVSDC/DC is used as post-stage circuit of vehicle charger to further improve efficiency. The design method of several key parameters and the corresponding control strategies are given based on the analysis of the principles of the main circuit topology. The simulation and experimental results verify the feasibility of the design of the new vehicle charger.
