Welcome to Capacitors in Power Electronics Applications


Capacitors are one of the key components in typical power electronic systems in terms of cost, volume, and reliability. Power electronics applications are consuming unprecedented quantities of electrolytic capacitors, film capacitors, and ceramic capacitors. This industrial/PhD course will discuss the sizing, modeling, and reliability analysis of capacitors from an application perspective, focusing on both classical and emerging power electronics applications. It is the latest research outcome of several PhD projects and industrial collaboration activities. The course will cover the following aspects:

  1. Basics of capacitors and its functions in power electronic converters
  2. Emerging capacitor technologies and latest developments
  3. Capacitor sizing criteria in power electronics by considering steady-state performance, transient and stability performance under both normal and abnormal operations
  4. Reliability of electrolytic capacitors, film capacitors, and ceramic capacitors
  5. Mission profiled based electro-thermal-lifetime modeling of capacitors
  6. Condition monitoring and protection of capacitors in power electronics applications
  7. Capacitor minimization techniques in power electronic systems
  8. Case studies in DC-DC converters, Modular Multi-Level Converters (MMC), photovoltaic inverters, wind power converters, adjustable-speed-drives, Solid-State-Transformers (SST), and ultra-low inductive capacitor bank design.

Prerequisites: Basic understanding of power electronics circuits and control

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 three 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.
