Abstract:
A wireless power transmitter and a method for operating the wireless power transmitter are provided, which transmit charging power to a wireless power receiver. A control signal is provided that includes time information and load change information, and a load change of the wireless power receiver is detected during a period of time corresponding to the first time information. If the detected load change of the wireless power receiver corresponds to the load change information included in the control signal, a determination is made that the wireless power receiver is admitted for charging.
