Abstract
A power supply device has a first power supply capable of storing and discharging electric power, a second power supply connected in series to the first power supply and capable of storing and discharging the electric power, an isolated DC-DC converter including a primary side terminal to which the first power supply is connected, and a secondary side terminal to which the second power supply is connected, and a power supply control unit that controls a voltage of the second power supply using the isolated DC-DC converter. A direct-current voltage outputted from the first power supply and the second power supply connected in series is inputted to a first inverter, converted into an alternating-current voltage by the first inverter, and then supplied to a vehicle drive motor.
