Abstract
Official abstract text for this publication.
A wireless power transmitter which wirelessly transmits a power to a wireless power receiver. The wireless power transmitter includes a transmission resonance coil configured to wirelessly transmit a power; a power source configured to supply the power to the transmission resonance coil; and a detector configured to detect an existence state of the wireless power receiver. Further, the power source supplies the power with a transmission pattern which is discrete at a predetermined time interval for a specific time to detect the existence state of the wireless power receiver and minimize a loss of the power, and the power source continuously supplies the power if the wireless power receiver exists.
