Summary:An electronic device according to various embodiments comprises: a housing; a conductive coil; a power transmission circuit electrically connected to the conductive coil and configured to transmit power wirelessly out 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 modifies the power to be emitted through the conductive coil, monitors a frequency of a signal and/or an electromagnetic wave emitted through the conductive coil, and adjusts the voltage level from the voltage source based on at least one result on the monitored frequency. According to the present invention, it is possible to effectively prevent electromagnetic interference within an available range of the frequency. 다양한 실시 예에 따르면, 전자 장치에 있어서, 하우징; 도전성 코일; 상기 도전성 코일과 전기적으로 연결되고, 상기 도전성 코일을 통해 전력을 무선으로 상기 하우징 외부로 전송하도록 구성되는 전력 전송 회로; 상기 전력 전송 회로와 전기적으로 연결되는 전압원(voltage source); 및 상기 전력 전송 회로와 상기 전압원 간에 전기적으로 연결되는 제어 회로를 포함하며, 상기 제어 회로는, 상기 도전성 코일을 통해 방출할 전력을 변경하고, 상기 도전성 코일을 통해 방출되는 신호 및/또는 전자기파(electromagnetic wave)의 주파수를 모니터하며, 상기 모니터한 주파수에 적어도 일부 결과를 기반하여 상기 전압원으로부터의 전압 레벨을 조정하도록 구성될 수 있다.
