Abstract: A method for additive manufacturing of an article having a controlled magnetic anisotropy includes: forming a metallic layer of the article using additive manufacturing, the metallic layer having a magnetic anisotropy aligned in a first direction; forming a subsequent metallic layer of the article using additive manufacturing, the subsequent metallic layer having the magnetic anisotropy aligned in a second direction different from the first direction; and repeating the forming of subsequent metallic layers of the article to form at least a portion of the article, each subsequent metallic layer having the magnetic anisotropy aligned in a different direction than a previous metallic layer.

Abstract: Unique systems, methods, techniques and apparatuses of a modular power transformer are disclosed. One exemplary embodiment is a matrix power transformer including a plurality of block assemblies each including a plurality of transformer modules, each transformer module including a primary winding coupled to an input and a secondary winding coupled to an output, the inputs of each transformer module in one block assembly being coupled together and the outputs of each transformer block being coupled together. One of the secondary windings includes a plurality of taps structured to be selectively coupled to the output of the associated transformer module assembly or another secondary winding of the associated module assembly.

Abstract: A transformer having a transformer core that forms a magnetic flux path between and through a top yoke, leg, and bottom yoke of the transformer core. A winding can be disposed about the leg. Further, a flitch plate, which can have at least one slot that is configured to reduce eddy losses generated by the winding, can be disposed adjacent to the leg and extend between the top yoke and the bottom yoke. The flitch plate can be clamped to the top and bottom yokes by top and bottom clamps, respectively. The top and bottom clamps can each include at least one cutout that reduces an attraction of stray flux from the winding and into the corresponding top and bottom clamps. Additionally, at least one of the top clamp and the bottom clamp can include an internal lattice structure.
