Beschreibung
Zusammenfassung:	A train traction power supply device, comprising a diode rectifier set, a four-quadrant converter set, and a central controller. The diode rectifier set, the four-quadrant converter set, and the central controller are connected in parallel to an alternating current power network and a direct current contact network. The central controller is connected to the four-quadrant converter set. The central controller is used for adjusting the output current of the four-quadrant converter set according to voltage and current of the alternating current power network and the voltage of the direct current contact network. The central controller is further used for receiving an inversion instruction comprising a de-icing current value sent by a de-icing control device, and switching the train traction power supply device to an inversion working position according to the inversion instruction, so that an energy cycle is formed among the four-quadrant converter unit of the train traction power supply device, a zone to be de
