Winding configuration as part of an integrated structure for a medium frequency transformer

Abstract

A method for producing a coil for a transformer, in particular for a medium frequency transformer for a resonant DC/DC converter or a dual active bridge DC/DC converter, is disclosed which: providing a plurality of M>1 conductive foil strips, each having a first ending and a second ending; stacking the plurality of conductive foil strips to obtain a foil strip stack having a first ending and a second ending, wherein an electrically insulating layer is provided between any two adjacent foil strips; electrically interconnecting the first endings of all conductive foil strips to a first terminal; for each of the conductive foil strips providing a connector at the second ending of the foil strip; and coiling up the foil strip stack from the first end.
