Title:
POWER RECEIVING COIL STRUCTURE AND WIRELESS POWER FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/137431
Kind Code:
A1
Abstract:
A power receiving coil structure receives power from a power feeding device provided with a plurality of power feeding conductor patterns extending in a Y-axis direction in an XYZ orthogonal coordinate system, comprises a first loop-shaped conductor (21) and a second loop-shaped conductor (22) which are formed on an XY plane such that an electric current is induced by linkage of magnetic flux in a Z-axis direction therewith, and have a right-left asymmetric shape when an X-axis direction is defined as a right-left direction, and is provided with a resonance circuit in which inductance which the first loop-shaped conductor (21) and the second loop-shaped conductor (22) have is used as the inductance of an LC resonance circuit.
