Our research aims to investigate incipient faults of drive components (i.e. motors, power semiconductors) and create online fault diagnosis / failure prognosis tools to establish early warning system for power electronics systems. The rapid and widespread deployment of drives and power devices raises significant reliability concerns, particularly for mission and safety critical systems due to limited field data and potential uncertainties. Continuously monitoring these systems is essential to prevent unexpected shutdowns and catastrophic failures that may result in fatal accidents or significant operation loss. However, current diagnostic engineering tools are not mature enough to detect or identify failure precursors in real time, leading to a major reliability gap in power conversion systems. In order to move drive technologies forward reliably, we investigates progressive degradations and parameter shifts in power devices as well as develops online degradation monitoring tools. These tools lay foundations of self-monitoring, smart-energy conversion systems that can recognize failure precursors at the earliest stage and prevent catastrophic failures.
