WIRELESS POWER RECEIVING APPARATUS FOR LOW HEAT AND METHOD THEREOF

摘要

The present invention is to control the charge of a battery with low heat by receiving a wireless power signal transmitted from a wireless power transmission device. A control part controls an impedance matching/control part and matches impedance when a power receiving coil receives the wireless power signal. The control part determines the elapsed time of charging power at a power transmission device and the charge load condition of the power transmission device according to a current level detected by a current detection part. The generation of heat is minimized by selectively turning on a high heat generation transformation part and a low heat generation transformation part according to the determined charge load condition and the power transmission device is charged with electric power.
