Zusammenfassung:	The utility model relates to a modular energy-feedback tractive power supply device, which comprises a multi-winding transformer, a plurality of PWM rectifier units and a central controller. The multi-winding transformer is provided with a primary winding and a plurality of secondary windings which are connected in pairs in the same manner; each secondary winding of the transformer is connected with one PWM rectifier unit; the direct current outputs of the PWM rectifier units are connected in parallel with a direct current bus of the complete power supply device; by adopting voltage and current closed-loop control, a direct current voltage outer loop is arranged on the central controller; and a current inner loop based on a synchronous rotary coordinate system is arranged on each PWM rectifier unit. The power supply device has the remarkable advantages of easy modularization, high capacity, bidirectional energy transmission, high power factor, less current harmonics, steady direct current voltage and the like
