1. An electric drive for a vehicle at least partially propelled by an electric motor, the drive comprising:

  • a vehicle drive train;

    a power converter operatively coupled to the drive train and comprising;

    an EMI shielding assembly including a support incorporating integral EMI shielding features and at least partially defining an electrical reference plane, and an enclosure at least partially surrounding the support and electrically coupled to the reference plane; and

    a power electronics circuit supported on the support;

    the shielding assembly providing contiguous shielding having intrinsically low impedance paths for EMI originating from the power electronics circuit and from sources external to the shield assembly during operation.
