摘要： The invention comprises an inverter/converter yielding high frequency harmonics and/or non-sixty Hertz output coupled to a high frequency inductor-capacitor filter apparatus. For example, an inverter/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, where the minimum carrier frequency is above that usable by an iron-steel inductor, such as greater than ten kiloHertz at fifty or more amperes. An inductor-capacitor filter, comprising an inductor having a distributed gap core material, receives power output from the inverter/converter and processes the power by passing the fundamental frequency while reducing amplitude of the harmonic frequencies.

摘要： A high frequency inductor filter cooling apparatus, method of manufacture, and method of use thereof is described. In one embodiment, an inductor is potted in an epoxy-silica mixture to facilitate thermal transfer from the inductor. The inductor is optionally used with a capacitor to filter/invert/convert power. The inductor optionally comprises a distributed gap core and/or a powdered core material. In one example, a minimum carrier frequency used with the filter is above that usable by a traditional wound iron-steel inductor, such as greater than seven hundred or ten thousand Hertz at fifty or more amperes. Optionally, the inductor is used in an inverter/converter apparatus in conjunction with a notched low-pass filter, a low pass filter combined with a notch filter and a high frequency roll off filter, and/or one or more of a silicon carbide, gallium arsenide, and/or gallium nitride based transistor.

摘要： The invention comprises an inductor mounting method and apparatus. An about annular inductor is mounted using a non-conducting mount element passing at least into a center opening of the inductor. Mounting hardware forces an edge surface of the mount into proximate contact with an edge of the inductor, where the mount and mounting hardware minimally contact the inductor. The mount optionally includes holes and/or grooves to further reduce mount/inductor contact, which aids liquid, convective, and/or radiative cooling of the inductor. The inductor is optionally composed of particles of magnetic material coated with carbon and embedded into an epoxy to yield a distributed gap material.

摘要： The invention comprises a phase change inductor cooling system. The cooling system uses a non-conductive refrigerant in proximate and/or in direct contact with an inductor. Heat from the inductor changes the refrigerant from a liquid to a gas phase, which removes heat from the inductor. The gas phase refrigerant is subsequently removed from the inductor to remove heat from the environment about the inductor. The refrigerant is optionally recirculated using the steps of condensing and/or compressing the refrigerant prior to reintroduction into the environment proximate and/or in direct contact with the inductor.

摘要： The invention comprises an inductor mounting method and apparatus. An about annular inductor is mounted using a non-conducting clamp element passing at least into a center opening of the inductor. Mounting hardware forces the clamp element toward a mounting surface to edge mount the inductor, where the mounting hardware, non-conducting clamp element, and mounting surface minimally contact the inductor. The minimal contact allows greater surface area for liquid, convective, and/or radiative cooling of the inductor. The inductor is optionally composed of particles of magnetic material coated with carbon and embedded into an epoxy to yield a distributed gap material.
