PHM 2021 Keynote Speech 9

Condition and Health Monitoring of Power Electronic Systems – State of the Art and Outlook


Power electronic converters are applied almost everywhere today when electricity is generated, transmitted, converted, or utilized, from mobile phones to electric vehicles, from renewable energy generation to industrial manufacturing. While our society is moving forward to digital transformation, data analytics, e-mobility, and Industry 4.0, power electronics technology plays an increasingly important role in controlling and converting electrical energy in a precise way. They are all “energy-hungry” applications, and electrical energy is the essential element behind them. Applications such as e-mobility and offshore wind demand cost-effective and robust condition and health monitoring solutions for operation optimization and predictive maintenance for the power electronic converters used. This keynote will discuss: 1) state-of-the-art methods and the gap between academic research and industrial applications in condition and health monitoring in power electronic converters; 2) several methods which have promising features to bridge the gap and the outlook towards industrial applications.
