Disclosed are a method and an apparatus for impedance matching using an isolated resonator in a wireless power transmission system. A wireless power transmission apparatus according to an embodiment of the present invention comprises: a switching unit which turns on and off a connection between a source resonator and a power supply unit; and a control unit which estimates a distance between the source resonator and a target resonator and adjusts an impedance of the source resonator to be matched with that of the target resonator. |
