Abstract
An electronic device includes a power transmitting circuit configured to transmit power to a wireless power receiver, a communication circuit configured to perform communication with the wireless power receiver, and a control circuit configured to control the power transmitting circuit to apply first power to a coil of the power transmitting circuit, control the power transmitting circuit to stop applying the first power and to prevent power from being applied to the coil during a first period, identify a first Q-factor during the first period, control the power transmitting circuit to apply, to the coil, a second power based on a calibration operation for identifying at least one parameter used for identifying a power loss during power transmission, control the power transmitting circuit to stop applying the second power and to prevent power from being applied to the coil during a second period, identify a second Q-factor during the second period, and identify a validity of the at least one parameter based on the first Q-factor or the second Q-factor.
