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.
