1. A wireless power transmitter comprising:

  • a power generator configured to generate tracking power using a resonance frequency, the tracking power being used for a resonance impedance tracking or a resonance frequency tracking;

    a source resonator configured to transmit the tracking power to a target resonator;

    a mismatching detector configured to detect a mismatching between the target resonator and the source resonator; and

    a controller configured to adjust the resonance frequency, or an impedance of a repeater resonator when the mismatching is detected, the repeater resonator being used to perform an impedance matching between the target resonator and the source resonator.
