    Abstract: A method and electronic device for performing wireless charging are provided. The electronic device includes a housing, a conductive coil, a power transmission circuit electrically connected to the conductive coil, and configured to wirelessly transmit power to an outside of the housing through the conductive coil, a voltage source electrically connected to the power transmission circuit, and a control circuit electrically connected between the power transmission circuit and the voltage source. The control circuit is configured to change power radiated through the conductive coil, monitor a frequency of a signal and/or electromagnetic waves radiated through the conductive coil, and adjust a level of a voltage from the voltage source based on at least a part of a monitored result of the frequency.

    Abstract: A wireless power transmitter for charging a wireless power receiver is provided. The wireless power transmitter includes a power transmission unit configured to transmit power for charging the wireless power receiver, by using a current applied to the power transmission unit, a communication module configured to receive out-of-band communication signal from the wireless power receiver and a controller configured to apply the current to the power transmission unit to transmit power in response to receiving the out-of-band communication signal from the wireless power receiver.
