Abstract

A wireless power receiver and a wireless power reception method are disclosed. The wireless power receiver includes a charging element, a receiving coil configured to wirelessly receive power from a wireless power transmitter, a rectifier configured to convert an alternating current (AC) voltage generated from the receiving coil to a direct current (DC) voltage, and to output the DC voltage, a voltage converter configured to generate a charging current to charge the charging element, based on the DC voltage output from the rectifier, a current measurer configured to measure the charging current transferred to the charging element, and a controller configured to control a level of the charging current generated from the voltage converter based on a result of the measuring.
