Abstract:
A method for controlling a wireless power transmitter and a wireless power transmitter are provided. The method includes applying a detection power for detecting a change in a load impedance of the wireless power transmitter; detecting the change in the load impedance of the wireless power transmitter; receiving, from a wireless power receiver, a first signal within a preset time period after detecting the change in the load impedance; determining whether a reception intensity of the first signal is greater than a threshold; and based on determining that the reception intensity of the first signal is less than or equal to the threshold, stopping a communication with the wireless power receiver.
