Winding Arrangement for Planar Transformer and Inductor

Abstract

Abstract: The invention relates to a winding arrangement (31) for a planar transformer, in particular for high frequency AC transformation, or for an inductor. In order to provide a winding arrangement (31) for a planar transformer or for an inductor which exhibits the advantages of planar winding arrangements and reduces or avoids the skin-effect, a winding arrangement (31) for a planar transformer, in particular for high frequency AC transformation, or for an inductor is proposed including at least two conduction layers (37, 39), each conduction layer (37, 39) having an inner hole (45) and comprising a plurality of conductor paths (19, 27), which are electrically insulated from each other and which lead from an outer circumference (21) of said conduction layer (37, 39) to an inner circumference (23) of said conduction layer (37, 39) adjacent to said inner hole (45) in a spiral form.
