    • 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.
    • 一种用于在电动或混合动力电动车辆中降低电力逆变器和电池的电气连接中的共模电流产生的电磁噪声的系统。 一对间隔开的电导体沿着车辆底盘延伸并将电力逆变器电连接到电池。 导电金属板位于间隔开的电导体之间。 该金属板至少与功率逆变器和电池/电动机两者电连接到底盘。 此外,需要更多的连接点来保持两个点之间的距离小于EMI要求的最大频率的一半波长,最优选地,该金属板通过无限连接点电连接到机箱。 金属板被定位成使得金属板比电导体和车辆底盘之间的空间更接近电导体。
