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.

Magnetic structures for large air gap

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.

Multiple cells magnetic structure for wireless power

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.
