Abstract: An electronic device includes a housing including a first plate, a second plate spaced apart from the first plate and facing the first plate, and a side member at least partially surrounding a space between the first plate and the second plate, a display located in the space and visible through the first plate, a conductive coil parallel to the second plate and disposed between the display and the second plate, a wireless charging circuit electrically connected to the conductive coil, and a processor operationally connected with the display and the wireless charging circuit. The processor receives a power control signal from an external device, applies a charging current to the conductive coil, based on the power control signal, senses whether a specified event occurs while the charging current is applied, and when the specified event occurs, transmits information for setting a charging power corresponding to the specified event to the external device.

Abstract: According to an embodiment, a wireless power transmitting device may include a transmission coil, a DC/DC converter configured to output a driving voltage, an inverter configured to output AC power to the transmission coil, and a controller. The controller may be configured to output a first control signal for generating the AC power having a first frequency to the inverter, measure a demodulated voltage generated by demodulating a signal applied to the transmission coil, and output, to the inverter, a second control signal for generating the AC power having a second frequency different from the first frequency, based on a first peak-to-peak value identified in the demodulated voltage being a preset first value or more. The inverter may output the AC power having the second frequency to the transmission coil based on the second control signal. Other various embodiments are possible as well.
