Abstract
A winding assembly for a transformer includes a wire winding and a sheet winding. The wire winding includes a spirally wound insulated wire and the sheet winding includes a metallic winding sheet that forms a single turn winding. Instead of winding the wire winding on a bobbin, sleeve or the like, the wire winding is attached directly to a surface of the winding sheet by means of a self-bonding technique.
