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.

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.
