Power Conversion Systems and Methods with Power Air Core Inductors

Abstract

Disclosed are implementations that include an energy storage element for power conversion systems, including an inductor structure including multiple interwoven air core inductors, with each air core inductor including at least one set of wire winding defining an interior core that is free of any other structure. The energy storage element further includes multiple coupling terminal sets electrically coupled to the at least one set of wire winding of respective ones of the multiple interwoven air core inductors of the inductor structure, with the multiple coupling terminal sets configured to electrically couple the inductor structure to circuitry of a power conversion system. In some embodiments, the multiple interwoven air core inductors comprising the inductor structure may be orthogonal to each other. In some embodiments, the inductor structure may include three interwoven air core inductors, with the inductor structure being electrically couplable to circuitry of a 3-phase power conversion system.
