1. A wireless power transmitter comprising:

  • a source resonator configured to transmit wireless power by resonating with a target resonator;

    a first power supply configured to supply power to the source resonator;

    a first switch configured to turn ON/OFF a connection of the source resonator to the first power supply; and

    a controller configured to match an impedance of the source resonator by estimating a distance between the source resonator and the target resonator.
