    摘要： A resonance power transfer system and a method for tracking resonant impedance in the resonance power transfer system are provided. An apparatus for tracking resonant impedance in a resonance power transfer system may include: a load sensor configured to detect the impedance of a load connected to a target device that receives resonance power; a target reflection signal detector configured to detect a reflection signal corresponding to the resonance power; a target impedance tracking unit configured to track the resonant impedance by adjusting a determination factor of a resonant frequency; and a target control unit configured to control the tracking of the resonant impedance based on whether there is a change of the impedance of the load, the reflection signal is detected, or both.

    摘要： Provided are a resonance power generation apparatus and method for wireless power transmission. The resonance power generation apparatus may include a voltage controller to receive an input of an alternating current (AC) signal of a first frequency band and to output a direct current (DC) voltage having a constant level, a power converter to separate the DC voltage into a voltage waveform and a current waveform by a switching pulse signal of a second frequency band, and a resonance power generator to generate an AC resonance power from the voltage waveform and the current waveform.

    摘要： A wireless power transmission device and method are provided. An amount of power transmitted wirelessly by the wireless power transmission device may be controlled based on information to be transmitted by the wireless power transmission device, such that the information may be transmitted without using any additional device for information transmission. Additionally, an internal impedance of a terminal may be controlled based on information to be transmitted by the terminal, and a reflected wave of a transmission signal transmitted by the wireless power transmission device may be then controlled, such that the information may be transmitted without using any additional device for information transmission. Therefore, no further device may be desired, and thus a power consumption amount may be reduced, and there may be no need to match a communication part for information exchange with a transmission part for wireless power transmission.
