Abstract

A EMI filter for an electric vehicle propulsion system, comprising a first and second capacitive element electrically connected in parallel with first and second power conductors, an inductive element electrically connected in series with the first power conductor and separating the first and second capacitive elements, and first and second junctions electrically connecting the second capacitive element to an electronic switch, wherein the sum of intrinsic inductances of the first and second junctions is less than the intrinsic inductance of the second capacitive element.
