SELF-RESONANT COIL, CONTACTLESS POWER TRANSFERRING APPARATUS, AND VEHICLE

WIPO Patent Application WO/2010/038297

A1

There is provided a self-resonant coil (110, 240) used in a contactless power transferring apparatus capable of at least one of transferring and receiving electric power by magnetic field resonance. A coil is defined as a virtual coil (440), wherein the coil has a circular cross-sectional shape of a cross-section perpendicular to the extending direction and, when viewed with a cross-section perpendicular to the extending direction of the self-resonant coil (110, 240), the length of the circumference defining the circular cross-section is equal to the length of the segment defining the outer circumference edge of the cross-section of the self-resonant coil (110, 240). At least one of the radial direction width and the axis direction length of the self-resonant coil (110, 240) in the cross-section perpendicular to the extending direction of the self-resonant coil (110, 240) is less than the diameter of the cross-section of the virtual coil.
