Abstract (en)
A triangular transformer is provided. It comprises a core including at least three distinct elongated frame sections, each having two end portions, the frame sections being composed of layered sheets of a ferromagnetic material, wherein the frame sections are mounted together to form the triangular core, and wherein each end portion of a first frame section abuts at least one end portion of a second frame section at a joint region, and wherein in at least one joint region comprising a first end portion of a first frame section and an abutting first end portion of a second frame section, the normal vectors of the abutting end portions of abutting sheets have the same direction, and wherein the at least two normal vectors are substantially parallel to a longitudinal axis of the transformer, and/or a cross-sectional plane through the at least one joint region and perpendicular to the abutting sheets of that at least one joint region is substantially parallel to the longitudinal axis. Further, methods for producing such transformers are provided.
