Abstract
A multi-core common-mode current suppression device (CMD), such as a balun and line isolator, includes at a pair of spaced cores. The cores may be separated by a spacer, such that in the case of a pair of toroidal cores, the axial centers of the cores may be arranged parallel to each other or coaxial with each other. Such a configuration allows the multi-core (CMD) to achieve higher levels of overall common-mode impedance (CMI) as compared to that of existing CMDs that utilize a stacked core configuration.
Claims20
A current suppression device comprising:
- a first core having an aperture;
- a second core having an aperture, said second core spaced apart from said first core;
- a spacer positioned between said first core and said second core;
- and
- a conductive wire forming at least one at least partial winding through said aperture of said first core, and said conductive wire forming at least one at least partial winding through said aperture of said second core.
