SYSTEM FOR POWER TRANSMISSION |
摘要 |
<p>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 EpsilonMuΪrequirements, 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.</p> |
