A power supply device for a vehicle includes a power storage device, a connector to which a power cable can be connected, an inverter, a coil provided separately from a stator coil of the rotating electric machine, and a connection switching unit switching connection relations among the power storage device, the connector, the inverter, and the coil. In a first operation mode, the connection switching unit sets the connection relation such that electric power from the power storage device is supplied to the inverter without using the coil and can drive the rotating electric machine, and in a second operation mode, the connection switching unit sets the connection relation such that the coil and the inverter are used to constitute a voltage conversion circuit and voltage conversion can be performed between a voltage of the connector and a voltage of the power storage device. |
