Abstract
In some embodiments, the instant invention involves an electrical system that at least includes: a three-phase inductor, including: a core, including: a plurality of core lamination pieces. having: a first core lamination piece and a second core lamination piece; where the first core lamination piece includes a plurality of first laminations that have a first shape and arranged in a first pattern to form a plurality of first differential mode gaps; where the second core lamination piece includes a plurality of second laminations that have a second shape and arranged a second pattern to form a plurality of second differential mode gaps; where the first pattern and the second pattern are distinct; where the first core lamination piece and the second core lamination piece are positioned at a particular orientation of the first pattern to the second pattern so that to increase a common mode inductance of the core.
