WIRELESS POWER RECEIVING APPARATUS, METHOD AND APPARATUS FOR CONTROL WIRELESS POWER RECEPTION IN WIRELESS POWER RECEIVING APPARATUS

摘要

PURPOSE: A wireless power receiving device, a method for controlling wireless power receiving in the wireless power receiving device and a device thereof are provided to decrease waste of wireless power by not receiving the wireless power when the wireless power is not necessary, without resonance. CONSTITUTION: A wireless power receiving device includes a target resonator(210), a resonator switch(220) and a resonator controller(260). The target resonator includes a capacitor and an inductor, and receives electromagnetic energy from a source resonator. The resonator switch controls resonance of the target resonator by removing capacitance of the capacitor when it is turned on. The resonator controller controls turn-on of the resonator switch when a user requests blocking of wireless power or efficiency of receiving wireless power is lower than predetermined efficiency.
