摘　　要：分析了永磁发电机的变速变载运行模式及其与发动机输出特性的匹配。永磁发电机-发动机组采用全波整流输出,通过调节工作转速调节电功率输出;与动力电池并联组成车载供电系统,以电池端电压为参量,采用优化策略,高效率地为驱动电机系统供电,满足电动汽车的动力需求和降低燃油消耗需要。It discussed variable speed and variable load operation modes of permanent magnet generator （PMG） and its output characteristics matching to the engine. Full-wave rectification is used in the output of PMG and engine unit to adjust the electric power output by controlling its operating speed. Generators and batteries are designed in parallel in the in-car power supply system. In order to satisfy power requirements of electric vehicle and reduce its fuel consumption, battery terminal voltage is used as reference and optimized strategy is applied to supply power for the motor drive system.
