<p>An EMI filter for an electric vehicle propulsion system, comprising a first (62) and second (72) capacitive element electrically connected in parallel with first (130) and second (132) power conductors, an inductive element (106) electrically connected in series with the first power conductor (130) and separating the first (62) and second (72) capacitive elements, and first (134) and second (136) junctions electrically connecting the second capacitive element (72) to an electronic switch (68), wherein the sum of internal inductances (135, 137) of the first (134) and second (136) junctions is less than the internal inductance (75) of the second capacitive element (72).</p> |
