Abstract: A first electronic device for wirelessly transmitting power may include a power transmission circuit, memory, a pulse generator, a foreign object detection circuit configured to detect a foreign object located in a path in which power is wirelessly transmitted through the power transmission circuit, and a control circuit. The control circuit may be configured to wirelessly transmit power to a second electronic device, based on an alternating current (AC) input voltage applied to the power transmission circuit, generate a trigger signal synchronized with a first time corresponding to a specified voltage of the input voltage through the pulse generator, store an output value of the foreign object detection circuit in the memory based on the trigger signal, the output value being identified at the first time, continuously obtain the output value stored in the memory from the memory during a specified time until before the trigger signal of a next period is received at the memory from the pulse generator, and detect the foreign object based on the output value obtained during the specified time.
