He’s project addresses challenges with wide bandgap (WBG) semiconductor switches, which can significantly enhance energy efficiency and power density of propulsion drivetrains. However, the fast-switching speed of WBG switches can induce reflected voltage stress on the stator windings and high-frequency current in a propulsion machine’s bearings, leading to premature aging or failure. This phenomenon has become a pressing concern for safety-critical applications such as electric ships and aircrafts, particularly for medium-voltage high-power propulsion systems.

He’s project, will develop an advanced integrated solution to address such challenges and improve the propulsion system’s reliability.

He joined the UK Department of Electrical and Computer Engineering in January 2019 after working at GE Global Research and Rockwell Automation. He’s research interest includes power electronics, motor drives, transportation electrifications and renewable energy. His team’s research has been sponsored by NSF, DOE, NASA, DOD, high-tech industries and non-profit institutions.
