Patent ID: 8675379

Claim:
A power-converting apparatus comprising: a base plate; a first direct current (DC) bus and a second DC bus; a first power semiconductor component electrically coupled directly to one of said buses, the first power semiconductor component disposed on a first substrate physically coupled to the base plate, wherein the first power semiconductor component is the only power semiconductor component disposed on the first substrate and comprises a high-temperature, wide bandgap material, wherein the substrate is exposed to a heat flux based on an operational temperature of the first power semiconductor component; at least a first capacitor coupled across the first and second DC buses; at least second and third capacitors respectively coupled across respective ones of said first and second buses and an alternating current (AC) return path, wherein said at least first, second and third capacitors is each located inside the power-converting apparatus to establish circuit connections sufficiently proximate to the first power semiconductor component to reduce a formation of parasitic inductances, and further wherein said at least first, second and third capacitors is each located physically apart from the substrate and thereby not exposed to said heat flux; and a second power semiconductor component electrically coupled directly to the other of said buses, the second power semiconductor component disposed on a second substrate physically coupled to the base plate, wherein the second power semiconductor component is the only power semiconductor component disposed on the second substrate and comprises a high-temperature, wide bandgap material, wherein the second substrate is exposed to a heat flux based on an operational temperature of the second power semiconductor component, and further wherein said at least first, second and third capacitors is each located physically apart from the second substrate, and further wherein all power semiconductor components disposed on the first and second substrates together form only one single-phase leg of the power-converting apparatus.
