    摘要： A method and apparatus for controlling wireless power transmission are provided. An output power of a source device may be wirelessly transmitted to a target device via a resonator. The source device may detect a change in a current of the output power, and may request the target device to verify a state of the target device. The source device may determine a state of a wireless power transmission based on the change in the current and the state of the target device. The source device may control wireless power transmission based on the determined state of the wireless power transmission.
