Abstract:

The invention comprises an inductor, such as used in processing transmission of a 3-phase power system. The inductor comprises a flat/rectangular winding with a narrow edge of the flat winding wound around a core, where the width of the winding exceeds three times the height of the inductor facing edge of the winding. The inductor optionally comprises a distributed gap particle core and/or is wound in parallel with multiple windings. Optionally, the inductor is used as part of an equal coupling common mode electrical system for processing the 3-phase transmission and/or a high frequency inverter comprising a switching device, such as a silicon carbide metal-oxide-semiconductor field-effect transistor.

International Classification:

H03H 7/09
H01F 27/08
H03H 7/01
H03H 1/00

Abstract:

The invention comprises an electrical system apparatus for processing three-phase power, comprising: a first, second, and third inductor connected on a first end to a first common magnetic field carrying plate and connected on a second end to a second common magnetic field carrying plate, where the three inductors are equidistant from each other and/or equidistance from a central axis, which yields an equal coupling common mode inductor-capacitor based filtering apparatus. Generally, inductor placement symmetry and/or equal magnetic field permeabilities between each pair of the three inductors balances magnetic fields within each inductor at each point of time, where each of the three inductors is connected to a single phase of three-phase power, the three phases offset from each other by one-third of a period.
