摘要： The invention comprises a high frequency inductor filter apparatus and method of use thereof. In one embodiment, an inductor is used to filter/convert power, where the inductor comprises a distributed gap core and/or a powdered core material. The inductor core is wound with one or more turns, where multiple turns are optionally electrically wired in parallel. In one example, the minimum carrier frequency is above that usable by an iron-steel inductor, such as greater than ten kiloHertz at fifty or more amperes. The core is optionally an annular core, solid rod core, or a core used for multiple phases, such as a ‘C’ or ‘E’ core. Optionally, the inductor is used in an inductor/converter apparatus, where output power has a carrier frequency, modulated by a fundamental frequency, and a set of harmonic frequencies, in conjunction with one or more of a silicon carbide, gallium arsenide, and/or gallium nitride based transistor.

摘要： The invention comprises a high frequency inductor filter apparatus coupled with an inverter yielding high frequency harmonics and/or non-sixty Hertz output. For example, an inductor/converter apparatus is provided that uses a silicon carbide transistor to output power having a carrier frequency, modulated by a fundamental frequency, and a set of harmonic frequencies. A filter, comprising an inductor having a distributed gap core material and optional magnet wires, receives power output from the inverter/converter and processes the power by passing the fundamental frequency while reducing amplitude of the harmonic frequencies.
