Industrial/PhD Course: Reliability in Power Electronics Systems


09.11.2021 kl. 08.30 - 12.11.2021 kl. 15.30



Professor Huai Wang,, Aalborg University, Denmark


Professor Huai Wang, Aalborg University 
Professor Francesco Iannuzzo, Aalborg University 
Assistant Professor Dao Zhou, Aalborg University
Reliability Advisor Peter de Place Rimmen 

ECTS:   4 


The course will be the latest research outcomes of the Center of Reliable Power Electronics (CORPE). Since 2013, more than 170 participants from universities and companies have been trained in this 3-day course. By considering the feedbacks from participants and newly obtained research results from CORPE in the last few years, the 2021 version of the course will be 4 days focusing on failure mechanisms and degradation models of active power devices and capacitors, system-level reliability assessment and design tools, and reliability testing methods.  The course will have the following five main parts:  

  1. Introduction to modern reliability and robustness approach 
  2. Reliability testing methods and testing data analysis (e.g., Weibull)  
  3. Long-term wear out and single-event abnormal operation of active power modules and capacitors  
  4. Power electronics system-level reliability assessment and design tools 
  5. Condition monitoring and thermal control of critical power electronic components  

Day 1 – Modern reliability engineering approach (Lecturer: Peter de Place Rimmen, 08:30 – 16:30) 

  • L1   Training in understanding Weibull 
  • Exercises 1 - Basic concepts of statistics 
  • L2   Introduction to modern reliability in Industry 
  • L3   MCF curve, cost of poor reliability, robustness 
  • L4   Lifetime budgets, degradation 
  • Exercise 2 - Lifetime estimation using provided data 

Day 2 – Reliability of Power Electronic Components (Lecturers: Huai Wang and Francesco Iannuzzo, 08:30 – 16:30) 

  • L5   Reliability of active switching devices (IGBT modules and SiC MOSFETs)  
  • L6   Reliability of passive components (capacitors and magnetic components) 

Day 3 – Reliability of Power Electronic Systems – Part 1 (Lecturers: Huai Wang and Dao Zhou, 08:30 – 16:30) 

  • L7   Reliability challenges in power electronics and design for reliability concept 
  • L8  Reliability prediction of a single converter – case study for fuel-cell backup power supply 
  • Exercise 3 - Design of a PV inverter with 10 years of B10 lifetime (Class exercises based) 

Day 4 – Reliability of Power Electronic Systems – Part 2 (Lecturers: Huai Wang and Dao Zhou, 08:30 – 15:30) 

  • L9   System-level thermal modeling and reliability prediction – case study for a modular multi-level converter 
  • L10  Simplification methods for electro-thermal-lifetime modeling 
  • L11  Reliability prediction of multiple converter systems 

The course also includes 3 lab sessions scheduled on Day 2 and Day 3.   


Basic understanding of power electronics, power semiconductor devices, capacitors, and basic statistics.   

Form of evaluation: 

Case study exercise and report submission
