ABSTRACT:
A multiphase inductor assembly includes an elongate conductor assembly including a plurality of bus bars that are arranged in parallel. A plurality of magnetic core material rings (e.g., ferrite or mu metal rings) surround the conductor assembly and are distributed along a length thereof. Terminals are electrically coupled to the bus bars and disposed between spaced apart ones of the magnetic core material rings. In some embodiments, the conductor assembly, in cross-section, includes respective ones of the bus bars disposed in respective quadrants. For example, each of bus bars may have a quarter-cylinder shape and may be arranged such that the conductor assembly has a circular cross-section. In other embodiments, each of the bus bars may have a polygonal cross-section, e.g., may be formed from standard rectangular bar stock.
