摘要
An apparatus for wirelessly transferring power comprises a first coil having a first winding path and a second winding path. The apparatus comprises a holder configured to hold the first coil and the second coil in a predetermined winding pattern. Each of the first and second winding paths comprise a plurality of successive winding groups. In each of the plurality of successive winding groups, at least a portion of each winding of consecutive windings is disposed on top of an immediately previous winding on the holder for a predetermined number of windings. Each of the successive winding groups of the first winding path is disposed along an outer perimeter of an immediately previous winding group and each of the successive winding groups of the second winding path is disposed along an inner perimeter of an immediately previous winding group.
