The invention discloses a regenerative braking energy feedback device and a power supply system. When the railway vehicle is braked, a first direct-current voltage of a direct-current bus of the railway vehicle is converted into a second direct-current voltage required by a direct-current power grid through the M first energy feedback converters, and the second direct-current voltage is converted into a second alternating-current voltage required by an alternating-current power grid through the N second energy feedback converters and the N power grid transformers. Therefore, the regenerative braking energy can be fed back to the alternating-current power grids with the different voltage levels and can also be fed back to the direct-current power grids with the different voltage levels, the feedback mode of the regenerative braking energy is more flexible, and the expansibility is higher.

    本发明公开了一种再生制动能量回馈装置及供电系统,在轨道车辆制动时将轨道车辆的直流母线的第一直流电压通过M个第一能馈变流器变换为直流电网所需的第二直流电压、通过N个第二能馈变流器和N个电网变压器变换为交流电网所需的第二交流电压。由此可见,本发明不仅可以实现将再生制动能量回馈至不同电压等级的交流电网,还可以回馈至不同电压等级的直流电网,再生制动能量的回馈形式更加地灵活、可拓展性更强。
