The Delphi team, including CREE/Wolfspeed for SiC power devices, with packaging by Delphi supported by Oak Ridge National Laboratory, and guidance from Volvo and other OEMs resulted in a robust, high performance integrated double-side cooled SiC-based Power Module that meets or exceeds the targets identified by DOE in the original FOA. The double-side cooled packages were designed to be scalable for voltages up to 800V and for phase currents up to 500Arms and that can be paralleled for currents up to 90Arms. These modules were confirmed and demonstrated in a traction drive inverter intended for an inverter for a specific OEM vehicle application and showed improved performance as compared to inverter systems with silicon based IGBTs and Diode with losses 70% lower at lower currents and up to 40% lower at peak current levels. This teaming resulted in a WBG integrated power module to be used in an inverter manufactured in Kokomo, Indiana, which will be manufacturable in volume at a cost that will enable reduced vehicle to cost improved performance, particularly by reducing weight and space-claim for the power electronics, as well as improving reliability overall. The targeted use of this developed power module is for a vehicle traction drive to be manufactured in the CY 2021 timeframe. The direct impact of this project will accelerate commercialization of advanced wide bandgap power semiconductor technology for electrified vehicles of all types, increasing their energy efficiency and marketability. In turn, more efficient and more marketable electrified vehicles will have the overall impact of reducing greenhouse gas emissions and other air pollutants, along with reducing our nation?s dependence on foreign energy sources.
