Reliability in Power Electronics Systems (2020)

Welcome to Reliability in Power Electronics Systems


Description:

The course covers the latest research outcomes of the Center of Reliable Power Electronics (CORPE) at Aalborg University. 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 2020 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.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
