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 2022 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.
