Abstract:
A method for controlling a wireless power transmitter for charging a wireless power receiver may comprise the operations of: transmitting power for charging; receiving a first PRU dynamic signal indicating completion of charging, from the wireless power receiver, applying a beacon for detecting the wireless power receiver on the basis of a load change to a resonance circuit of the wireless power transmitter; receiving, from the wireless power receiver, a first advertisement signal including information indicating that charging is not requested; and ignoring the advertisement signal and maintaining application of the beacon.
