CHARGING CONTROL DEVICE, CHARGING CONTROL METHOD AND WIRELESS POWER RECEIVING DEVICE EQUIPPED WITH SAME

摘要

A charging control device includes a capacitor, a comparison unit and a switching unit. The capacitor is charged with a voltage converted from power received from a wireless power sending device. The comparison unit compares the voltage of the capacitor with a reference voltage, and generates an output signal according to the result of the comparison. The switching unit is connected to the front end of the capacitor and is switched by the output signal from the comparison unit so as to control whether to supply the converted voltage to a load terminal.
