Abstract
An apparatus for wireless power charging includes a first charging coil with a first conductor arranged in a winding pattern with a first winding around a center point and each successive winding of the first charging coil is further away from the center point than the first winding and any previous windings. A second charging coil includes a second conductor wound with respect to the first charging coil where each coil of the second charging coil is arranged between each winding of the first charging coil. The first charging coil and second charging coil are connected in parallel. A ferrite structure is positioned adjacent to the first charging coil and the second charging coil.
