Abstract
A contactless charging apparatus and method for contactless charging are disclosed. In one embodiment of the contactless charging apparatus, a primary electromagnetic structure and a secondary electromagnetic structure are disposed in an opposing relationship with primary wedges of the primary electromagnetic structure facing secondary wedges of the secondary electromagnetic structure with a non-magnetic gap therebetween. Coils may be positioned in spaces defined by circumferentially slotted areas between the primary and the secondary concentric cores. A non-resonance circuit is formed between the primary electromagnetic structure and the secondary electromagnetic structure to provide a contactless electrical energy transmission from the primary electromagnetic structure to the secondary electromagnetic structure with the use of a time-varying electromagnetic field.
