Abstract
An apparatus and a method for protecting a wireless power receiver from excessive temperature caused by charging are provided. The wireless power receiver includes a power receiver for receiving wireless power in an Alternate Current (AC) form from a wireless power transmitter; a regulator for regulating the wireless power; a power management unit for controlling charging by providing the regulated wireless power to a battery; a temperature measurement unit for measuring a temperature of a point in the wireless power receiver during reception of the wireless power; and a controller configured to provide a control signal for the wireless power receiver to be charged with a regulated charging power if a temperature measured by the temperature measurement unit exceeds a preset temperature.
