Abstract
An electrical noise-filtering assembly includes first and second busbars. The first busbar is spaced from the second busbar at a fixed distance sufficient to induce the proximity effect. As arranged, high frequency noise having high order harmonics adhere to the surfaces spaced by the fixed distance. Noise can be removed efficiently by disposing low equivalent series resistance (ESR) noise filters between the surfaces where the noise harmonics concentrate.
