The invention discloses an alternating-current and direct-current train power supply system which comprises a pantograph and an alternating-current motor used for driving a locomotive, and the pantograph is connected with the alternating-current motor through an alternating-current and direct-current switching unit. The alternating-current and direct-current switching unit comprises an input line connected with the pantograph, an alternating current processing device used for processing and converting single-quadrant alternating current into three-phase limited alternating current, and a direct current processing device used for processing and converting direct current into three-phase limited alternating current; the input line is selectively connected with the input end of the alternating current processing device and the input end of the direct current processing device through a change-over switch, and the alternating current motor is connected with the output end of the alternating current processing device and the output end of the direct current processing device. According to the alternating-current and direct-current train power supply system, the train can be rapidly and conveniently switched to run on two different rail lines, the rail switching running efficiency of the train can be improved, the operation difficulty is reduced, and the labor intensity of workers is relieved.

本发明公开了一种交直流列车供电系统，包括受电弓和用于驱动机车的交流电机，受电弓通过一交直流切换单元与交流电机相连，交直流切换单元包括与受电弓相连的输入线路、用于将单象限交流电处理转化为三相限交流电的交流处理装置和用于将直流电处理转换为三相限交流电的直流处理装置，输入线路通过转换开关可选择的与交流处理装置的输入端和直流处理装置的输入端相连，交流电机与交流处理装置的输出端和直流处理装置的输出端相连。该交直流列车供电系统使列车能够在两条不同轨道线路上快速、方便的切换运行，可提高列车换轨运行效率、降低操作难度、减轻人工劳动强度。
