摘要： A system for reducing electromagnetic noise generated by common mode currents in electrical connections of a power inverter and battery in an electric or hybrid electric vehicle. A pair of spaced apart electrical conductors extends along the vehicle chassis and electrically connects the power inverter to the battery. An electrically conductive metal plate is positioned in between the spaced apart electrical conductors. This metal plate is electrically connected to the chassis adjacent at least both of the power inverter and the battery/motor. Besides this, more connecting points are required to keep the distance between two points less than half wavelength of the maximum frequency of EMI requirements, and most preferably this metal plate is electrically connected to the chassis all the way with infinite connecting points. The metal plate is positioned so that the metal plate is closer to the electrical conductors than the space in between the electrical conductors and the vehicle chassis.

摘要： A method for identifying EMI sources in a system having a plurality of electrical components connected together by cables wherein each set of two electrical components connected by a cable forms a potential EMI source. A plurality of antennas are positioned around the vehicle and the EMI from each antenna is measured over a plurality of frequencies and the frequencies having an EMI greater than a predetermined threshold and a measurement profile of the received EMI versus the antennas for each of the identified frequencies is created. EMI reception is then simulated for each potential EMI source and a simulation profile of the received EMI versus the antennas is plotted for each potential EMI source. The actual source of the EMI is then identified by comparing the measurement profile with the simulation profile for the potential EMI sources at each frequency to determine a match of the profiles.
