摘要： A leakage magnetic field shielding device comprises: a leakage magnetic field determining unit for determining phase and magnitude of a leakage magnetic field based on information obtained from a power supply device and a current collector device; a shielding current controller for determining a shielding current based on the phase and magnitude of the leakage magnetic field and supplying the determined shielding current to the leakage magnetic field shielding device; and a shielding unit for shielding the leakage magnetic field by generating a shielding magnetic field in accordance with the supply of the shielding current. The shielding unit has a multiple resonance characteristic depending on an arrangement of capacitors and coils and is disposed to surround the power supply device or the current collector device. The shielding magnetic field has resonance frequencies canceling magnetic fields corresponding to fundamental frequency and multiple frequency of the leakage magnetic field.

摘要： A wireless power supply system has a power sending resonance coil (1), a power receiving resonance coil (2), and a relay resonance coil (3). The power sending resonance coil (1) 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 (1), and receives power wirelessly with a magnetic field resonance mode generated by synchronization of the resonance frequency. The relay resonance coil (3) has the same resonance frequency characteristic as the power sending resonance coil (1) and the power receiving resonance coil (2), and relay power from the power sending resonance coil (1) to the power receiving resonance coil (2) wirelessly with the magnetic field resonance mode generated by synchronization of the resonance frequency with them.
