讲座摘要：

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 power electronic converters used.
This tutorial aims to present the state-of-the-art condition and health monitoring methods for power electronic components and converters. It starts with a brief introduction to there liability and availability challenges of power electronics in different applications, underlining the importance, function, and benefits of condition monitoring, and their demands on field applications. Then, it discusses the condition monitoring methods for power semiconductor switches, capacitors, and power electronic converters. A few case studies for three-phase inverter and DC-DC converter applications are used to illustrate the principles and associated practical considerations. Finally, it gives perspectives on the challenges and the gap between academic research and industrial applications in condition and health monitoring in power electronic converters. The target participants are: 1) University researchers who are interested in in condition and health monitoring techniques for power electronics, latest condition monitoring techniques, component-level and converter-level solutions; 2) Power electronic engineers who would like to have a better understanding in how to select and involve a proper condition monitoring technique in the power electronic system they are developing.
