Abstract: New and Useful magnetic structures are provided. One feature of the magnetic structures is that they are configured to help minimize the air gap reluctance, improving the magnetic structure's coupling coefficient. Another feature is that reducing the windings AC impedance of a magnetic structure is produced by shielding the winding under ears formed of magnetic material. Still another feature is that leakage inductance of a magnetic structure is reduced, by making ears with cuts which converge toward the magnetic rods that are used in the formation of the structure.

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.

Abstract: Several new and useful features for a magnetic structure are provided. One feature is that the magnetic structures are configured to help minimize the winding's AC losses, improving the system's efficiency. Another feature is that the combination of different magnetic hats creates a shaping path for the magnetic field. Still another feature is that a magnetic hat concept can be applied to a variety of magnetic core shapes.

Abstract: The magnetic component structures of this invention provides an improved magnetic core and winding arrangement which increases the inductive coupling between the primary and the secondary part compared to a similar single cell structure. A new and innovating wireless power transfer magnetic structure is provided that increases the efficiency of the wireless power transfer by means of increased inductive coupling. Another advantage of these structures is low susceptibility to misalignment errors. The invention comprises two or more identically structural units named cells. The magnetic structure is made of magnetically permeable material and consists of two identical parts, the primary side and the secondary side, that are separated by a large air gap or any other electrically or magnetically nonconductive material. The two identical parts compose the wireless transformer. The transformer includes also copper wire winded around specific areas of the magnetic structure.
