    摘要： 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.

    摘要： A power bridge for an electric vehicle propulsion system, comprising a switching circuit including first and second switching elements operable between "on" and "off" states and a midpoint detector coupled to the switching circuit for detecting a failure of at least one of the first and second switching elements, where the midpoint detector is capable of detecting and isolating a failure when the switching elements are in the "on" or the "off" states.

    摘要： A power bridge assembly for providing electric current to stator windings of an electric motor used in an electric propulsion system for an electric vehicle. The power bridge is assembled on a laminated bus bar. An upper plate of the bus bar connects to one side of a high voltage battery, a lower plate of the bus bar connects to the other side of the high voltage battery, and an insulation layer is sandwiched between the upper and lower plates. Electrical switches and capacitors sandwich the laminated bus bar. With this structure, two fasteners, one for positive voltage and one for negative voltage, can connect the bus bar, capacitors, and switches both electrically and mechanically. The sandwich structure eliminates parasitic inductance from the electrical connections.
