13. A method of controlling a wireless power transmitting device, comprising:
-
detecting either one or both of a voltage or a current of a transmission coil in response to a wireless power transmitting device transmitting a wireless power to a receiving device through the transmission coil; generating information of a distance between the wireless power transmitting device and the receiving device based on either one or both of the voltage or the current of the transmission coil; generating information of a reference efficiency corresponding to the information of the distance; comparing the reference efficiency to a power transmission efficiency of the wireless power transmitting device; and reducing a magnitude of the wireless power in response to the power transmission efficiency being lower than the reference efficiency. - View Dependent Claims (14, 15, 16)
