摘　　要：电动汽车作为一种高效、节能、零排放的交通工具,将成为未来城市的主导。而对充电机的研究,将直接影响未来电动汽车的发展。针对传统电动汽车充电机的结构,提出了一种高效且高功率因数、低谐波含量、能量双向流动的充电机结构。该结构前级采用三相电压型PWM整流器,后级DC/DC变换电路采用电流可逆斩波电路。针对前级,推导了一种功率前馈的无差拍控制,该方法实现了系统的快速、无差整流。针对后级,提出了一种基于马斯定律的自适应多阶段恒流充电控制,能够有效地延长蓄电池的使用寿命和缩短充电时间。最后通过仿真与实验验证了所提结构与方法能够实现充电机的双向高效、高功率因数、低谐波功能。As a kind of high efficient energy-saving and zero mission vehicle, electric vehicle would play a leading role in the city life in the future. The research of charger would have a direct impact on the future development of electric vehicle. Based on the traditional electric vehicle charger structure, a high efficiency, high power factor, low harmonic and a dual purpose of charger structure was put forward. Three-phase voltage source PWM rectifier was used by preceding stage of this structure. Current reversible chopper circuit was used by the later stage. For the preceding stage, a power feed-forward dead-beat control method was derived, which could realize quickly rectifying. For the later stage, a multi-stage constant current charging control based on the law of Mass was proposed, which could effectively prolong the service life of battery and shorten the charging time. Finally, simulation and experiment results verify the correctness of the proposed structure and the method can achieve dual purpose high-efficiency,high-power-factor and low harmonic function of charger.
