Abstract
An energizable magnetic core for use in an inductor or a transformer includes a plurality of legs extending from the back yoke. The back yoke is formed in a loop arranged to provide a magnetic circuit. Each of the plurality of legs have a first end adjacent to the back yoke and a second end extending away from the back yoke. With the legs positioned upon the back yoke, a cover yoke is positioned adjacent to the second end of each of the plurality of legs. The cover yoke is also formed in a loop such that the cover loop is arranged to provide a magnetic circuit. Coils are positioned upon the legs of the energizable magnetic core. In one embodiment, amorphous metal may be used to construct the energizable magnetic core.
