<p>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 (82). An upper plate (84) of the bus bar connects to one side of a high voltage battery, a lower plate (86) of the bus bar connects to the other side of the high voltage battery, and an insulation layer (88) 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.</p> |
