WIRELESS POWER TRANSMISSION APPARATUS AND METHOD

摘要

PURPOSE: A wireless power transmitting apparatus and a method thereof are provided to easily recognize the presence of a non-target receiver using the transmit power, transfer efficiency, and reflected wave of wireless power. CONSTITUTION: A source part(630) transmits wireless power to a target receive. A controlling part(650) checks the change amount of receiving power which is measured at the target receiver. The controller determines the presence of a receiver which does not permit the reception of wireless power or a non-target receiver based on the transmission result of the wireless power which is transmitted to the target receiver. The transmission result of the wireless power includes one of the amount of the reflected wave reflected from the transmit power and target receiver of the wireless power.
