Abstract
There is provided a power system designed to enable electronic devices to be powered. The system includes a planar surface on which a device to be powered is placed. Within the power system and substantially parallel to the planar surface are multiple primary transformer windings formed in a multi-layer structure that couple energy inductively to a secondary winding formed in the device to be powered. A winding of a second layer is offset relative to a winding of a first layer.
