Abstract
A wireless power transmitter configured to transmit a wireless power to a wireless power receiver and a method for controlling the wireless power transmitted from the 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 caused by a placement of the wireless power receiver, detecting the change in the load impedance of the wireless power transmitter, receiving a first signal from the wireless power receiver, determining whether a reception intensity of the first signal is greater than a threshold, and transmitting a second signal to the wireless power receiver based on detecting the change in the load impedance and determining whether the reception intensity of the first signal is greater than the threshold.
