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.
