Abstract: A transformer and a method of manufacturing a transformer are disclosed. The transformer can include a transformer core with at least three core limbs which are arranged in parallel with respect to one another and perpendicular to corner points of an area spanned by a polygon, and wherein axial end regions of each of the at least three core limbs transition into a respective yoke segment arranged transversely with respect to the axial end regions. Main windings can be arranged around each of the at least three core limbs in a hollow-cylindrical winding region. A magnetic cross section of a respective core limb can be greater than a magnetic cross section of the respective yoke segment. Additional windings can be electrically connected to a respective main winding and can be arranged around each of the respective yoke segments.

Abstract: A transformer core is disclosed, which can include at least three hollow-cylindrical rectangular shaped core-discs wound from a magnetic band-like material, wherein two opposed limb areas and an upper and lower yoke area can be formed along a circumferential path. The core-discs can include one first and at least one second slanted area parallel to the circumferential path in the belonging limb area. The at least three core-discs can be connected according to a polygonal layout at their first slanted areas, which can be arranged adjacently face to face. Conical shaped polygonal adapter plates fitted to the polygonal layout within the upper and lower yoke areas, which can be clamped together.
