The invention discloses an electric train, a train power supply system, a control method and a storage medium. The power supply system comprises a control module, a direct current pre-charging module, a direct current backflow module, an input conversion module, an alternating current pre-charging module, a first rectification module, an inversion module, an isolation transformation module, a second rectification module, a voltage stabilization module and an output conversion module. And the control module is used for controlling on-off states of contactors in the input conversion module, the output conversion module, the direct-current pre-charging module, the direct-current backflow module and the alternating-current pre-charging module according to the first power supply mode and the second power supply mode so as to convert the first power supply mode into the second power supply mode and output the second power supply mode. According to the invention, conversion of multiple power supply systems between a single-wire system AC 1500V, a single-wire system AC 1000V, a single-wire system DC 3kV, a single-wire system DC 1.5 kV and a single-wire system DC double-wire system can be realized.
本发明公开了一种电力列车及列车供电系统、控制方法、存储介质,所述供电系统包括控制模块、直流预充电模块、直流回流模块、输入转换模块、交流预充电模块、第一整流模块、逆变模块、隔离变压模块、第二整流模块、稳压模块和输出转换模块;控制模块用于根据第一供电制式和第二供电制式控制输入转换模块、输出转换模块、直流预充电模块、直流回流模块和交流预充电模块中的接触器开关状态,以将第一供电制式转换成第二供电制式并输出。本发明可实现单线制AC1500V、AC1000V、DC3kV、DC1.5kV与直流双线制之间的多种供电制式转换。
