Abstract:
A wireless power supply system has a power sending resonance coil, a power receiving resonance coil, and a relay resonance coil. The power sending resonance coil has a predetermined resonance frequency characteristic, and transmits power wirelessly. The power receiving resonance coil has the same resonance frequency characteristic as the power sending resonance coil, and receives power wirelessly with a magnetic field resonance mode generated by synchronization of the resonance frequency. The relay resonance coil has the same resonance frequency characteristic as the power sending resonance coil and the power receiving resonance coil, and relay power from the power sending resonance coil to the power receiving resonance coil wirelessly with the magnetic field resonance mode generated by synchronization of the resonance frequency with them.
