1. A power supply device for supplying power to a load by combining a secondary battery and a capacitor, comprising:
- a bypass switch adapted to enable power to be directly supplied to the load from the capacitor by being switched to a connected state when a voltage of the capacitor is a voltage capable of driving the load; and
a first DC-DC converter adapted to enable the voltage of the capacitor to be stepped up and supplied to the load when the voltage of the capacitor drops below a minimum voltage capable of driving the load.
