The invention provides a maglev train power supply device and method.The power supply device comprises a plurality of converters and a controller, a traction inverter module in each converter comprises a switcher and a plurality of inverter basic units connected in series, and the working states of the inverter basic units comprise an inductance mode and a transformer mode; each inverter basic unit comprises an inverter and a transformer, and for any converter in work, the working states of the inverter basic units at different running speeds of the maglev train are changed through the switcher. And meanwhile, the controller is matched with the switcher so as to adjust the output of the plurality of inverter basic units at different running speeds of the maglev train. The method can solve the technical problem that the existing power supply method cannot meet the traction requirement due to insufficient output voltage in a single inductance mode.

    本发明提供一种磁悬浮列车供电装置及方法,该供电装置包括:多个变流器和控制器,变流器中的牵引逆变器模块包括切换器和串联连接的多个逆变器基本单元,所述逆变器基本单元的工作状态包括电感模式和变压器模式,所述逆变器基本单元包括逆变器和变压器,对于任意工作中的变流器,通过所述切换器改变不同磁悬浮列车运行速度下的多个逆变器基本单元的工作状态,并同时通过所述控制器与所述切换器相配合以调整所述不同磁悬浮列车运行速度下的多个逆变器基本单元的输出。本发明方法能够解决现有供电方法单一电感模式下输出电压不够,无法满足牵引需求的技术问题。
