Beschreibung
Zusammenfassung:	The invention provides a traction auxiliary converter device which comprises a traction converter and an auxiliary converter, the traction converter comprises at least two traction converters, each traction converter comprises an independent intermediate direct current loop, and each intermediate direct current loop comprises a capacitor, a discharge resistor, a first voltage detection sensor and a chopping resistor; the auxiliary converter comprises at least two auxiliary converter modules, the number of the auxiliary converter modules is the same as that of the traction converters, and the direct-current input ends of the auxiliary converter modules are connected with the first output ends of the independent intermediate direct-current loops of the traction converters in a one-to-one mode. And the auxiliary converter module is used for inverting the direct-current power supply into a three-phase power frequency PWM alternating-current power supply, so that the power utilization reliability of the train is i
