    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 is data transmission and reception that transmits and receives data using a wireless power between wireless power transmitter and a wireless power receiver. An in-band data communication apparatus using a wireless power may include a modulating unit configured to modulate data by mixing a predetermined signal and pulse signal-type data; a demodulating unit configured to detect reflected power generated due to impedance mismatching between a source resonator and a target resonator, and to demodulate received data based on a variance of the reflected power; a source resonance unit configured to transmit transmission power including the modulated data to the target resonator, and to receive the reflected power; and a controller to control the pulse signal-type data, and to control impedance matching between the source resonator and the target resonator.
