Abstract
According to various embodiments, there may be provided an electronic device comprising a coil, an inverter configured to provide power to the coil, a power providing circuit, a communication circuit, and a control circuit, wherein the control circuit is configured to control the power providing circuit to apply a first voltage to an input terminal of the inverter, the inverter outputting a first magnitude of power based on the application of the first voltage, control the power providing circuit to apply a second voltage lower than the first voltage to the input terminal of the inverter, based on the application of the first voltage being maintained for a specific time, identify, through the communication circuit, a first control error packet from the wireless power receiving device, while applying the second voltage, and identify a first value included in the first control error packet.
