Abstract: A wireless power transmission system and a method for increasing a coupling efficiency by adjusting a resonant frequency are provided. A device of the wireless power transmission system includes a resonator configured to transmit a wireless power, and a communication unit configured to receive information from another device. The device further includes a controller configured to determine a power transmission efficiency based on the information, and adjust a resonant frequency of the device, a resonant frequency of a relay device, and a resonant frequency of the other device, if the power transmission efficiency is less than or equal to a predetermined reference efficiency.

Abstract: An overvoltage protecting unit and an overcurrent protecting unit protect a power device from an overvoltage and an overcurrent using a comparator having hysteresis. An overtemperature protecting unit protects the power device from an overtemperature using a thermistor having a resistance that changes as a temperature of the thermistor changes.

Abstract: 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.
