A power supply device includes an electrical storage device and a bidirectional buck-boost converter having a charging function of starting charging of the electrical storage device based on input power from a power system of a vehicle, upon occurrence of a condition in which a voltage of the electrical storage device decreases to a first threshold and of stopping the charging of the electrical storage device, upon occurrence of a condition in which the voltage of the electrical storage device increases to a second threshold that is greater than the first threshold. The bidirectional buck-boost converter has a boost function of stepping up the voltage of the electrical storage device. The power supply device includes a control circuit configured to cause the boost circuit to perform a boost operation such that a boosted voltage that is higher than the voltage of the electrical storage device is supplied to a load device, and such that the boosted voltage is a constant voltage.
