摘要：
A method and apparatus to detect load fluctuation of a wireless power transmission are provided. A wireless power transmitter includes a resonator configured to wirelessly transmit, to a target device, an output power. The wireless power transmitter further includes a power detector configured to detect a current of the output power. The wireless power transmitter further includes a controller configured to detect a change in the current, and to detect a target load based on the change in the current. The target load includes a load of which the output power is applied thereto.
