Power-Dense High-Efficiency Engine-Coolant-Capable 200 kW Silicon Carbide Inverter for Heavy-Duty Vehicles
June 7, 2019 @ 1:30 pm - 4:00 pm EDT
Co-sponsored by: IEEE PES, IAS, IES, PELS
This presentation will discuss public information related to John Deere project funded by the US Department of Energy – PowerAmerica Institute at North Carolina State University, Raleigh. Through PowerAmerica, John Deere has formed a collaboration with researchers from the US Department of Energy National Renewable Energy Laboratory to develop a 200 kW 1050 VDC silicon carbide (SiC) dual-inverter. The SiC inverter converts vehicle engine power into electrical power needed for the permanent-magnet-motor based power-train used in heavy-duty construction and mining vehicles. The presentation will cover development and test verification of various technologies deployed in the successful realization of a power-dense (>40 kW/Liter) high-temperature (suitable for 115°C coolant) high-efficiency (> 98% over entre range of coolant) SiC dual-inverter. Test results from various generations of the SiC inverter will be presented. In April 2017, the Fargo, North Dakota-based John Deere Electronic Solutions (JDES) successfully demonstrated the SiC inverter in a John Deere 644K hybrid front loader vehicle, using the engine radiator fluid to cool the SiC power electronics. The SiC inverter technology demonstration took place at John Deere Dubuque Works (JDDW) in Dubuque, Iowa. Since then this SiC inverter has been operating on vehicles resulting over 2,000 hours experience from real-world application of SiC power electronics technology. The DOE-PowerAmerica funding has greatly helped John Deere to accelerate the development of SiC inverter technology including realization of key commercialization objectives.
