Abstract
The present disclosure relates to a wireless power receiver and a method therefor, the wireless power receiver comprising: a secondary coil which is magnetically coupled to a primary coil provided in a wireless power transmitter so as to receive wireless power from the wireless power transmitter; a shielding member for supporting the secondary coil; a power pickup unit including a rectifier circuit which rectifies an alternating current signal of the wireless power received by the secondary coil into a direct current signal; and a communication/control unit for controlling transmission of the wireless power and communicating with the wireless power transmitter. On the basis of the secondary coil and shielding member according to the present embodiment, slimming of an applied product may be achieved and, simultaneously, the same target performance index (required for a medium power level (for example, 60 W) standard) may be realized.
