Abstract (en)

[origin: WO9834244A1] A power transformer or inductor is disclosed. The winding (31) of the transformer/inductor is made of a flexible conductor (38) having electric field containing means forcing the electric field due to the electric current in the winding (31) to be contained within the insulating layer of the flexible conductor (38). The thickness of the insulating layer of the flexible conductor (38) is adopted in such a way to make the electric stress (33) constant throughout the length of the winding. The cross section area of the insulating layer of the flexible conductor (38) is thus optimized, providing for a transformer/inductor design with a high space factor.
