toroidal core consisting of coiled materials with at least two layers and inductor for power electronics.

摘要

The annular magnetic core is wound from at least 2 material layers, one of the layers provided by a magnetically and electrically conductive material, e.g. a dynamo plate, with a layer thickness of between 0.1 and 0.7 mm and the other layer provided by a non-electrically and non-magnetically conductive material, e.g. a paper or foil layer, with a reduced layer thickness of between 0.01 and 0.05 mm. An Independent claim for application of an annular magnetic core for an inductance in a power electronics circuit is also included.
