NON-CONTACT POWER FEEDING COIL AND NON-CONTACT POWER FEEDING SYSTEM
First Claim
1. :
- A non-contact power feeding coil that is used in at least one of a power feeding coil and a power receiving coil that configure a non-contact power feeding system, the non-contact power feeding coil comprising;
a coil through which an AC current of a specific frequency flows; and
a core that forms a section of a circulating magnetic path, which is interlinked with the coil,wherein in the coil, a wire having an insulating covering is wound around a conductor, anda covering thickness of the insulating covering is set so that the influence of a proximity effect that occurs at the specific frequency between adjacent portions of the wire is a predetermined amount or less.

Abstract
A power feeding coil that configures a non-contact power feeding system is provided. The power feeding coil is provided with a coil through which an AC current of a specific frequency flows, and a core that forms a section of a circulating magnetic path, which is interlinked with the coil. In the coil, a wire having an insulating covering is wound around a conductor, and a covering thickness of the insulating covering is set so that the influence of a proximity effect that occurs at the specific frequency between adjacent portions of the wire is a predetermined amount or less. According to this configuration, it is possible to freely adjust a separation distance between portions of the conductor by altering the covering thickness; and the occurrence of AC loss caused by a proximity effect may be appropriately suppressed.
