March 24, 2023 -- AMPERE Lab Presented Research Achievements in APEC-2023

March 22, 2023  -- The 2023 IEEE Applied Power Electronics Conference & Exposition (APEC), a flagship conference in power electronics was just held in Orlando, Florida, on March 19-23, 2023.

During APEC-2023, a fault-tolerant high-efficiency T-Type multilevel SiC propulsion inverter prototype was demonstrated in our industrial partner SanRex's booth. The high-performance SiC inverter was designed by our USP student Jonathan Taylor, under the supervision of Dr. He, sponsored by a NASA-KY EPSCoR URF program. For more details about this inverter, please refer to our patent and paper as follows: J. He and N. Demerdash, “Fault-tolerant topology for multilevel T-type converters,”  U.S. Patent 10,658,920, issued May 19, 2020, and our published paper J. M. Taylor, M. T. Fard and J. He, "A Multifunctional T-Type 4-Leg Inverter for Various Operation Modes of Electric Aircraft Propulsion," 2022 IEEE Transportation Electrification Conference & Expo (ITEC), Anaheim, CA, USA, 2022, pp. 1205-1210.

Meanwhile, a paper based on our recent research achievements from the NSF project (#2135543) on smart coils for AC motors was presented by our PhD candidate Majid T. Fard. Our academic collaborators on this NSF project include Dr. Fariba Fateh's team at Kansas State University. The objective of this project is to develop an ultra-compact high-efficiency mitigation solution for the reflected surge overvoltages in long-cable-fed SiC motor-drive systems. The main paper information is provided as follows, and the full version can be accessed in IEEE Xplore soon.
