Electronic device for wirelessly receiving power and method of operating the same

Abstract

According to an embodiment, an electronic device for wirelessly receiving power may include: a power reception circuit including a coil, an impedance compensation circuit electrically connected to the power reception circuit, a rectifier circuit electrically connected to the impedance compensation circuit, a battery electrically connected to the rectifier circuit, and a control circuit electrically and/or operatively connected to the impedance compensation circuit, the rectifier circuit, and the battery. According to an embodiment, the control circuit may be configured to: rectify, by controlling the rectifier circuit, power received wirelessly from an external electronic device through the power reception circuit and the impedance compensation circuit into direct current (DC) power. According to an embodiment, the control circuit may be configured to identify at least one of a voltage or a current of the rectified DC power. According to an embodiment, the control circuit may be configured to determine a duty cycle of a control signal to control the impedance compensation circuit, based on the at least one of the voltage or the current. According to an embodiment, the control circuit may be configured to adjust a first voltage output by the impedance compensation circuit by controlling the impedance compensation circuit based on the duty cycle. According to an embodiment, impedance of the power reception circuit may be compensated based on the adjusted first voltage of the impedance compensation circuit.
