Title:
SELF-RESONANCE COIL HAVING MULTILOOP FOR MAGNETIC RESONANCE WIRELESS POWER TRANSFER
Document Type and Number:
WIPO Patent Application WO/2012/150746
Kind Code:
A1
Abstract:
The present invention provides a magnetic resonance wireless power transfer system for increasing a coupling coefficient by separating a loop of a self-resonance coil into multiples and increasing a magnetic field generation in places having a transmission/reception resonance coil, reducing the magnetic field generated overall in the magnetic resonance coil by minimizing the magnetic field generation in portions without a loop, and having a frequency characteristic of a broadband for enhancing the reliability of power transfer efficiency in response to frequency fluctuation.
