WIRELESS POWER TRANSMITTER, WIRELESS POWER RECEIVER, AND CONTROL METHODS THEREOF

摘要

A method for controlling a wireless power transmitter configured to transmit power to a wireless power receiver is provided. The method includes applying a detection power for detecting change in load of the wireless power transmitter caused by the arrangement of the wireless power receiver; detecting the change in load of the wireless power transmitter at first time point; receiving a first signal from the wireless power receiver at second time point; and determining whether or not to transmit a second signal to the wireless power receiver based on at least one of: the difference between the first time point and the second time point, and a reception intensity of the first signal.
