ABSTRACT:
A power inverter for a hybrid automotive vehicle having a case with an interior and at least one electrical port mounted on the case to electrically connect electrical signals from the interior of the case to an exterior device. A cable connector is associated with each electrical port while a non-electrical sensing conductor extends serially through each electrical port and its associated cable connector. A circuit is provided which detects a break in the continuity of the sensing conductor and generates a signal representative of that break in continuity. The non-electrical sensing conductor thus minimizes the emission of EMI from the inverter. Additionally, a circuit board is mounted within the interior of the case by fasteners which minimize the spacing between the circuit board and the case to further reduce EMI emissions.
