Abstract:
An apparatus and a method for are provided for a wireless power receiver. The method includes receiving power from a wireless power transmitter; converting the power in an alternating current (AC) form into a direct current (DC) form and providing the converted power to a battery of the electronic device; measuring a temperature of a point in the wireless power receiver during reception of the wireless power; maintaining an amount of the converted power at a first level if the temperature is lower than a first temperature; decreasing the amount of the converted power to a second level which is lower than the first level if the amount of the converted power is at the first level and the temperature is higher than or equal to the first temperature; stopping providing the converted power to the battery if the temperature is higher than a second temperature; and transmitting, to the wireless power transmitter, a signal including status information of the wireless power receiver device and control information to control the wireless power transmitter.
