Abstract: 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.

Abstract: A wireless power receiver for transferring a power received from a wireless power transmitter to a load, the wireless power receiver including a receiving coil configured to receive an AC power from the wireless power transmitter, a rectifier configured to rectify the AC power into a DC power and a controller configured to monitor a DC voltage at an output of the rectifier, in which the wireless power receiver transceives information with the wireless power transmitter through an in-band communication, and the controller creates a control signal to adjust the AC power received from the wireless power transmitter and continuously is configured to charge the load when a charging state is changed.
