Abstract:
A power converter includes a field graded substrate, a plurality of power device dies attached to the field graded substrate, a polymer layer on the field graded substrate, one or more conductors over the polymer layer, and a plurality of power conditioning components mounted on the field graded substrate to form a power converter circuit. The field graded substrate includes a first conductor layer, a graded layer that blends conductor and insulator material, and a second conductor layer, the graded layer having an insulator core.
