1. 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 of driving voltages 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 of the driving voltages 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 a wireless power receiving device, while applying the second voltage,
identify a first value included in the first control error packet,
based on the identified first value being less than a threshold value, identify whether the second voltage corresponds to a threshold voltage,
control the power providing circuit to apply a third voltage lower than the second voltage to the input terminal of the inverter when the second voltage does not correspond to the threshold voltage,
identify, through the communication circuit, a second control error packet from a wireless power receiving device, while applying the third voltage,
identify a second value included in the second control error packet,
based on the second value being greater than the threshold value, identify that the wireless power receiving device is misaligned with the electronic device, and
perform at least one control operation based on identifying the misalignment of the wireless power receiving device,
wherein the driving voltages are decreased step-wise in response to a step-wise increase in control error packet values below the threshold.
