摘　　要：简要介绍了城轨车辆辅助系统低压电源的组成和功能,对低压电源系统采用的两种变流模式,即输入电源为电网电压的直接变流和输入电源为辅助逆变器输出的间接变流模式进行了探讨,并分析比较各种电路拓扑结构的特点,为城轨车辆低压电源的选用提出建议。The paper briefly introduced the composition and function of the low-voltage power supply of auxiliary system in urban rail vehicle. Discussed the two converting modes of the low-voltage power supply： directly converting mode whose power supply is power supply network, and indirectly converting mode whose power supply is auxiliary inverter, and analysis and comparison of the above mentioned circuits are made for getting their topological structure characteristics, and also the suggestion are made for the above mentioned issues.
