Document Type and Number:
WIPO Patent Application WO/2023/040207
Kind Code:
A1
Abstract:
A wireless transmission coil and an application thereof. A central non-magnetic flux region, and a peripheral magnetic flux region, which surrounds the central non-magnetic flux region and is spaced apart therefrom, are formed for the planar coil, and the planar coil comprises a plurality of co-directional scroll loops that are formed in series, wherein each scroll loop surrounds the central non-magnetic flux region and defines the peripheral magnetic flux region. The application of the planar coil in the present invention is more flexible, and the adverse effects, during an energy transmission process, caused by a magnetic interference component that needs to be arranged in a central non-magnetic flux region in some applications can be eliminated.
