Abstract

Det er vist en krafttransformator eller induktor hvor transformatorens/ induktorens vikling (31) er dannet av en fleksibel leder (38) med en anordning som inneholder et elektrisk felt og som tvinger det elektriske felt på grunn av den elektriske strøm i vik- lingen (31) til å være inneholdt i den fleksible leders (38) isolerende lag. Tykkelsen av den fleksible leders (38) isolerende lag er anordnet på en slik måte at den elektriske spenning (33) gjøres konstant gjennom hele lengden av viklingen. Tverrsnittsarealet av den fleksible leders (38) isolerende lag er således optimert, noe som sørger for en transformator/induktorkonstruksjon med en høy fyllfaktor.There is shown a power transformer or inductor in which the transformer / inductor winding (31) is formed by a flexible conductor (38) having a device containing an electric field and forcing the electric field due to the electric current in the winding (31). ) to be contained in the insulating layer of the flexible conductor (38). The thickness of the insulating layer of the flexible conductor (38) is arranged such that the electrical voltage (33) is made constant throughout the length of the winding. The cross-sectional area of the insulating layer of the flexible conductor (38) is thus optimized, providing a transformer / inductor construction with a high filling factor.
