1. A wireless power receiver comprising:
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 by transmitting a voltage control signal to the voltage converter, based on a result of the measuring.
