Abstract

Of special application in switched power supply units that have high operating frequencies. The transformer comprises a core and windings formed by planar wire turns. These wire turns are in the form of open rings of a conductive material coated with an insulating material, joined electrically inside the transformer window by a soldering process, having previously eliminated the insulating material they have in two segments of each ring. The end wire turns (E) differ from those in the centre (C) because they have at least one extension (P) that is used as a terminal of the transformer. To make assembly easier, they can have a notch (H) that is shifted progressively by an angle with respect to an origin so that the openings of the wire turns of a winding form a helix. <IMAGE>
