Abstract
An electronic device according to one embodiment of the present disclosure includes a conductive coil, a power generation circuit, and one or more processors operatively connected to the power generation circuit and may be configured to: compare an amount of transmission power to be supplied to a power reception device with designated threshold power amount, determine a designated frequency to be a frequency of a control signal for controlling the power generation circuit when the amount of transmission power is equal to or less than the designated threshold power amount, determine a phase of the control signal based at least in part on the amount of transmission power and/or the designated frequency when the designated frequency is determined to be the frequency of the control signal, transmit the control signal having the designated frequency and the phase to the power generation circuit to generate, based at least in part on the control signal, transmission power corresponding to the amount of transmission power, and supply the transmission power generated by the power generation circuit to the power reception device wirelessly via the conductive coil.
