Abstract
A power supply device for supplying power to a load by combining a secondary battery and a capacitor includes a switching element which switches the supply of power to the load from the capacitor, a DC-DC converter which enables a voltage of the capacitor to be stepped up and supplied to the load and a control unit which enables power to be supplied to the load by pulse-controlling the switching element, controlling the DC-DC converter to output a pulse current alternately with the switching element and combining the alternately output pulse currents if the voltage of the capacitor drops below a minimum voltage capable of driving the load.
