Patent ID: 7327024

Claim:
A power module assembly comprising: a plurality of power modules, each of said power modules comprising: a substrate comprising an upper layer, an electrical insulator and a thermal coupling layer, wherein said upper layer comprises at least one electrically conductive pattern and is configured for receiving at least one power device, wherein said electrical insulator is disposed between said upper layer and said thermal coupling layer, and wherein said thermal coupling layer is configured for thermal coupling to a base plate, an edge card connector comprising a first electrically conductive layer, an insulating layer and a second electrically conductive layer, wherein said insulating layer is disposed between said first and second electrically conductive layers, and wherein said first electrically conductive layer of said edge card connector is electrically connected to said upper layer of said substrate, and a plurality of electrical connections connecting a top side of the at least one power device to said second electrically conductive layer of said edge card connector; a plurality of receptacles configured to receive respective ones of said edge card connectors; and a back plane comprising a positive direct current (DC) bus layer, an output layer, and a negative DC bus layer, wherein said receptacles are mounted on said back plane.
