Abstract (en)

[origin: EP0590741A1] The winding former of the transformer/of the inductor consists of two separate flanges (F1, F2) and two boards (P1, P2) which hold these flanges spaced apart; the flanges and boards are held together by windings which loop around them. E-shaped cores, preferably ferrite cores (FK11 to FK13), have centre limbs (MS) which engage from the side between the boards of the winding former. The length of the boards is governed by the stack height of the core laminates or by the number of ferrite cores to be used. The same flanges can be used for transformers/inductors of different powers, only the length of the boards varying. <IMAGE>
