THREE PHASE TRANSFORMER WITH DUAL TOROIDAL FLUX RETURN PATH

The invention is a dry type Three-Phase Transformer with toroidal yoke. It develops high power density (ratio of power to active volume) in the magnitude of 3.0 times the existing three phase technology. The invention provides more power density and less stray magnetic field by use of a different shape and design. Particularly, it is a cylindrical shape that occupies less space. The invention is used for increasing and more efficiently delivering power to electrical equipment while being lighter and more compact. The main component is a toroidal core, which is wound with continuous tape of grain oriented silicon steel (GOSS) with no gaps and all the grains orientated in a preferred direction, being used as a yoke in the structure of the transformer.
