Integrated Three-level GaN Inverter and PMsynRM Motor for Electric Passenger Vehicles and Medium/heavy duty Trucks (GaNIn_PMsynRM)
Application
This project is to develop and integrate an 800V/200kW GaN-based three-level high-power-density inverter and permanent magnet assisted synchronous reluctance motor (PMsynRM). Integration of a GaN power inverter and a PMsynRM motor drive system consists of integrated GaN power modules, common-mode (CM) and DC-side electromagnetic interference (EMI) filters, dv/dt filter, sensors, heatsink, capacitors, and the motor, yielding high efficiency and high power density with low cost.
Research
Existing standalone PMSM and SiC inverter in UTK lab
The project is funded by U.S. Department of Energy for 39 months, starting from June 2024. UTK will provide the inverter, ABB focuses on the motor design, Oak Ridge National Laboratory (ORNL) will help design the heatsink and provide the high-power dynamometer, Lucid Motors will provide system specs and design guidance, the University of Michigan, Dearborn will design the control system of the inverter, and Rensselaer Polytechnic Institute (RPI) will design its integrated gate driver.
How WBG Can Help
The project marks one of first attempts of using GaN devices on high-power motor drive systems for electric vehicles.
