Title:
MAGNETIC-RESONANT-COUPLING POWER TRANSMISSION APPARATUS AND MAGNETIC-RESONANT-COUPLING POWER RECEPTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/074082
Kind Code:
A1
Abstract:
Disclosed is a magnetic-resonant-coupling power transmission apparatus provided with communication function, wherein the cost thereof is reduced. The magnetic-resonant-coupling power transmission apparatus (100) of a magnetic-resonant-coupling wireless power transmission system (10) is provided with a resonance coil (110), an AC power supply (130) that generates an AC current on the resonance coil (110), and a frequency varying unit (140) that varies the frequency of the AC current to be generated by the AC power supply (130) on the resonance coil (110), on the basis of communication data.
