The invention discloses a locomotive fireless feedback power supply device. The locomotive fireless feedback power supply device comprises a rectification module, an inversion module, a chopping boosting module and a power storage unit, wherein an input terminal of the rectification module is connected with an input terminal of a traction motor, an output terminal of the rectification module is connected in parallel with a charging capacitor and then connected with an input terminal of the inversion module, an output terminal of the inversion module is connected with a power supply load, and the power storage unit is connected with the charging capacitor through the chopping boosting module. The invention also discloses a locomotive fireless feedback power supply method. When a locomotive speed is greater than a preset speed, and the charging capacitor is charged to a preset voltage, the charging capacitor provides an excitation source to the traction motor, and the traction motor is switched to a power generation state from an idling state; a storage battery stops charging the charging capacitor, the inversion module is started, the voltage output by the traction motor is rectified by the rectification module and then inverted by the inversion module to output a power supply voltage. Both the device and method disclosed by the invention have the advantages of simplicity and convenience in operation, safety and practicality, capability of being independent from an original power supply system and the like.
