TILED WIRELESS CHARGING COIL SOLUTION FOR EXTENDED ACTIVE AREA

摘要

The disclosure generally relates to a method and apparatus for wireless charging station. In one embodiment, the disclosure provides an overlapping (or tiled) layout of a plurality of coils. Each coil may have a symmetric or an asymmetric turn layout. The disclosure also provides design optimization techniques configured to determine the optimal tile overlap distance and/or coil size to provide a substantially uniform electro-magnetic field over the surface of the wireless charging station.
