Title:

CONTACTLESS POWER FEEDING APPARATUS AND CONTACTLESS POWER FEEDING METHOD

Document Type and Number:

WIPO Patent Application WO/2011/122249

Kind Code:

A1

Abstract:

A contactless power feeding apparatus of one embodiment is provided with a power transmission resonant unit, and a power reception resonant unit that magnetically couples with the power transmission resonant unit, with resonance in magnetic field therewith. Power from a power supply is fed to the power reception resonant unit via the power transmission resonant unit, by having the power transmission resonant unit and the power reception resonant unit magnetically coupled through resonance in magnetic field. Either one of the power transmission resonant unit and the power reception resonant unit has a single prescribed resonance frequency, and the other one thereof has a plurality of resonance frequencies, including the single prescribed resonance frequency.
