A train rescue power supply circuit, a control method and a device, wherein the circuit is applied to a rescue train and comprises: a traction transformer, a rectification inverter composed of a first preset number of independent axis control circuits, and a traction motor; a second preset number of independent axis control circuits, comprising: a first power supply isolation switch, which is used for connecting or disconnecting the connection between a positive line of an intermediate direct current link of a corresponding independent axis control circuit and a train being rescued; and a second power supply isolation switch, which is used for connecting or disconnecting the connection between a negative line of the corresponding intermediate direct current link and the train being rescued. The positive lines and the negative lines of the intermediate direct current links of the second preset number of independent axis control circuits in the present invention may directly supply power to the train being rescued by means of the first power supply isolation switch and the second power supply isolation switch such that the train being rescued may maintain the normal operation of an auxiliary load during rescue and return, which improves user experience and reduces design costs.
