| description | A wireless power transfer pad for wireless power transfer with active field cancellation using multiple magnetic flux sinks includes a ferrite structure, a center coil positioned adjacent to the ferrite structure, and a plurality of side coils positioned around a perimeter of the center coil and positioned adjacent to the ferrite structure. A direction of current flow of the center coil is opposite a current flow in each of the plurality of side coils such that current flowing in a portion of the center coil adjacent to a portion of a side coil of the plurality of side coils is in a same direction as current in the portion of the side coil. |
