Multiple cells magnetic structure for wireless power
First Claim
1. Primary or secondary side pad for a wireless transformer for inductive power transfer through an air gap, including a first plate, a second plate, wherein at least two rods link the first and the second plate where a winding is wound around each rod, the rods being spaced from each other in a lateral direction, wherein a width of the plates in the lateral direction is larger than a distance between outer edges of the farthest rods in said lateral direction in a way that a whole area of in each plate extends beyond the surfaces of the farthest rods on two opposing sides, and wherein a thickness of each plate is smaller than a width of the plate and the length of the plate, the width being the extension of the plate in a lateral direction in which the rods are spaced and the length being the extension of the plate in a direction parallel to rods being linked to the respective plate, the thickness being the extension of the plate in a vertical direction perpendicular to the lateral and to a longitudinal direction which is parallel to rods.

Abstract
An improved primary or secondary side pad for a wireless transformer for inductive power transfer through an air gap is provided. The primary or secondary side pad includes a first plate, a second plate, and at least two rods which are linking the first and the second plate, where a winding is wound around each rod. A wireless transformer for inductive power transfer through an air gap includes a primary side pad and a secondary side pad of the transformer which is identical in shape and size.
