PROBLEM TO BE SOLVED: To provide a vehicle drive system suppressing harmonic content generated on a power supply side even when a train does not output a drive command for a power running or a braking but when the train is coasting or stopping.SOLUTION: A plurality of power conversion units includes a first power conversion unit for supplying a direct current to an auxiliary power supply device (APS) 7 and a second power conversion unit for not supplying a direct current to the auxiliary power supply device. When an OFF command is inputted as a drive command for an organized train, and also an ON command is being inputted as an operation command for the auxiliary power supply device, the plurality of power conversion units causes a converter for power supply of the first power conversion unit to operate to supply a direct current to the auxiliary power supply device, and causes a converter for power supply of the second power conversion unit to operate.SELECTED DRAWING: Figure 1 |
