Sept. 2, 2020 -- New NASA-KY Sponsored Project to Improve Aircraft Propulsion Drive Reliability

Sept 2, 2020 ---- NASA-KY sponsored a new research project with AMEPRE Lab to improve the reliability of civil aircraft propulsion drive systems. All-electric and hybrid-electric propulsion drives are the enabling technologies for next-generation civil aircraft, and the realibility of these propulsion drives has become more essential than ever for such safety-critical applications. In this project, the reliability of the propulsion drive systems operating in harsh enviroment (e.g., 50k feet altitude) will be investigated based on the proposed digital twin technologies. 

Jun. 10, 2020 -- Multiple Journal Papers Published on Electric Aircraft Propulsion

June 2020 -- Multiple papers authored or co-authored by Dr. He have been published in IEEE journals on the development of lightweight high-efficiency electric aircraft propulsion drives, which is an emerging technology to enable next-generation aircraft cleaner, quieter, cheapter, and more energy saving. These papers are listed below (available in IEEE Xplore):

May. 19, 2020 -- Patent Granted on Fault-Tolerant Power Converters

A patent titled "Fault-tolerant topology for multilevel T-type converters", U.S. Patent No. 10,658,920, was granted by USPTO on May 19, 2020. This patent, authored by Prof. JiangBiao He and Prof. Nabeel Demerdash, invented a new power converter concept that provides soft switching and high efficiency during normal operation while enables desired fault-tolerant capability under switching fault condition. Unlike the conventional power converters where high efficiency and high reliability are typically conflicting factors due to the redundancy of power electronics, this proposed concept can be very attractive for many safety-critical applications where both reliability and power efficiency are critical, such as propulsion drives in electric vehicles and electric aircraft, solar inverters, and the like. More details of this patent can be found on the USPTO Website.
