The invention relates to a power supply system for emergency self-walking vehicle-mounted energy storage equipment of a motor train unit train. The power supply system comprises an AC/DC converter, a DC bus, a storage battery pack and an isolated bidirectional DC/DC charger, the input alternating current is converted by the AC/DC rectifier; the isolation bidirectional DC/DC charger is connected with the DC bus and the storage battery pack. Damage caused by overlarge stress of the switch tubes can be avoided, distortion of output voltage is avoided, meanwhile, a power supply current loop is greatly shortened, the electric energy conversion efficiency is improved, the travelled distance of a train under the emergency working condition is prolonged, it is guaranteed that the train reliably drives out of a fault section, and the reliable operation capacity of a railway network is improved.

    本发明涉及一种用于动车组列车应急自行走车载储能设备供电系统,包括AC/DC变流器、直流母线、蓄电池组以及隔离双向DC/DC充电机;输入的交流电通过所述AC/DC整流器转换;所述隔离双向DC/DC充电机与所述直流母线和所述蓄电池组连接。本发明能够避免开关管应力过大造成损坏,避免输出电压产生畸变,同时,供电电流回路极大缩短,电能转换效率得到了提高,应急工况下列车的行驶里程得到延长,保障列车可靠驶出故障区间,提升铁路网可靠运行能力。
