Abstract
In one embodiment, a resonator includes a magnetic core, a winding wound around the magnetic core, and a parasitic loop element. The parasitic loop element is arranged so as to be interlinked with magnetic field generated by current flowing through the winding. In the parasitic loop element, an amount of flux linkage is adjusted.

10. A wireless power transmitting apparatus comprising:
-
a resonator wirelessly transmitting power from a high-frequency power supply with respect to a power receiving apparatus by mutual inductance; a communication unit communicating a power transmitting status or a power receiving status to the power receiving apparatus; and a control unit detecting transmission power, and controlling the transmission power based on detected result or received information of the communication unit, wherein the resonator includes a coil including a magnetic core, and a winding wound around the magnetic core, and a parasitic loop element arranged so as to be interlinked with magnetic field generated in the coil, and the control unit adjusts an amount of flux linkage of the parasitic loop element based on the fluctuation of a resonant frequency of the resonator or the inductance value of the coil. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
