Abstract
A power supply device includes: a first power storage device; a second power storage device that outputs voltage higher than the output voltage of the first power storage device and is connected in series to the first power storage device; a voltage converter connected to the output terminal of the first power storage device to output converted voltage; a second load connected to the output terminal of the voltage converter; and a control unit that controls the voltage converter at fixed boost ratio such that the converted voltage is the sum of the output voltage of the first power storage device and output voltage of the second power storage device. The output terminal of the first power storage device is connected to the second power storage device. The output terminal of the second power storage device is connected to the output terminal of the voltage converter.
