Abstract

A transformer core comprises at least one leg and at least one yoke part, wherein the cross section of the leg or the legs is regularly multi-edged with more than four edges. The core is made up or rings rolled from strips or constant width, whereby good electric properties are achieved. The transformer is also easy to manufacture and avoids waste of materials. 17 claims, 17 figures
