ABSTRACT:
An output voltage of a solar cell is supplied to a voltage converter. The voltage converter converts the input voltage into a predetermined voltage, and supplies it to a capacitor. The capacitor is charged by the output current of the voltage converter. The capacitor has a relatively large capacitance. A second voltage converter converts an input voltage from the capacitor into a voltage which is lower than the charged voltage of the capacitor and higher than a minimum operating voltage of a load. The load performs a predetermined operation using the output voltage of the second voltage converter.
