Abstract

In this paper, a novel overlapping approach between the copper foil windings and copper bar is presented. The electromagnetic field is computed and analyzed using three-dimensional (3-D) finite element method based on an actual SCB transformer with amorphous foil winding. The current density cloud of foil winding and copper bar is obtained using the magnetic vector potential method to visually observe the existence of skin effect. Then the current density of novel overlapping mode is computed and compared with the traditional one. The results show that the novel overlapping mode not only reduce maximum current density of foil winding, but also save material. The study of this paper is significant for practical manufacture and production.
