A method provides a portion of a transformer by forming a core by providing transformer core material, cutting individual laminations and bending them into generally C-shaped members, stacking some members to define a first core portion having a main leg and two opposing end legs, stacking other members to define a second core portion having a main leg and two opposing end legs, arranging the main legs in a back-to-back manner to define the core having a core leg defined by the two main legs, and opposing core yokes, defined by the end legs. Conductive material is wound directly around the core leg to form a primary winding and secondary winding in any order of arrangement, thus providing a first transformer portion. The transformer portion may be part of a single transformer or, when second and third transformer portions are provided, as part of a three-phase transformer. |
