A primary winding of a transformer is electrically connected to an overhead wire. A power converting device to be cooled is connected to a secondary winding of the transformer. A driving motor being a device to be cooled is connected to the power converting device. A cooling device is connected to a tertiary winding of the transformer. The cooling device is supplied with regenerative power of the driving motor to perform cooling operation to the device to be cooled. The regenerative power is boost in voltage by the power converting device and has superimposed thereon power from the overhead wire via the transformer. Thereby, the on-board device of a railway vehicle can be prevented from stopping or being output-controlled.
