Abstract
A winding arrangement for a planar transformer, e.g., for high frequency AC transformation, or for an inductor includes at least two conduction layers. Each conduction layer has an inner hole and conductor paths which are electrically insulated from each other and which lead from an outer circumference to an inner circumference of the conduction layer adjacent to the inner hole in a spiral form.
