Abstract:
A wireless power transfer (“WPT”) pad apparatus includes a first winding adjacent to the ferrite structure, where the first winding is arranged in a spiral-type pattern, and a second winding adjacent to the ferrite structure. The second winding is arranged in a spiral-type pattern and the second winding wound interleaved to the first winding. The first and second windings are arranged to compensate for a difference in length between the first winding and the second winding for portions of the first and second windings wound adjacent to each other.
