Abstract
A wireless power receiver for wirelessly receiving power from a wireless power transmitter comprises: a power reception circuit receiving electromagnetic waves emitted from the wireless power receiver so as to output power having an alternating current waveform; a rectifier for rectifying the power, having an AC waveform, outputted from the power reception circuit into power having a direct current waveform; a DC/DC converter for converting, into a voltage of a preset level, a voltage of the power having a direct current waveform, the power being rectified by the rectifier; a charger for charging a battery by using the power having a DC waveform, converted from the DC/DC converter; an alternating current ground connected to the power reception circuit and/or the rectifier so as to receive at least a portion of the power having an alternating current waveform; and a direct current ground connected to the DC/DC converter and/or the charger so as to receive at least a portion of the power having a direct current waveform, wherein the alternating current ground and the direct current ground can be disposed on different PCB layers, respectively.
