1. A modular power converter comprising:

  • an EMI shielding assembly including a cooled support incorporating integral EMI shielding features and at least partially defining an electrical reference plane, and an enclosure at least partially surrounding the cooled support and electrically coupled to the reference plane, the EMI shielding and the cooled support being electrically contiguous with one another; and

    a power electronics circuit supported on the cooled 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.
