Power electronics are essential for power conversion of Photovoltaic (PV) systems and their reliability of power electronics systems strongly affects the availability and consequently the levelized cost of energy (LCOE) of PV energy. According to field experience, the power electronics systems (e.g., PV inverter) are among the most fragile parts in PV systems that contribute to a majority of system downtime. With the demand to further reduce the cost of PV energy, the reliability of power electronics in PV systems needs to be improved to reduce the (unexpected) failure in field operation. This calls for a better design methodology as well as a proper control strategy.

This PhD course aims to address the reliability challenge and solution for power electronics in PV applications. It will cover the design aspects related to power electronics reliability for PV systems. A step-by-step modeling approach from mission profile to the reliability performance (e.g., failure rates) will be introduced. The reliability of key components such as power devices and dc-link capacitors will be elaborated in details, and solutions to enhance their reliability through the design and control methods will be discussed and demonstrated. Moreover, emerging solutions and new technology to further enhance the reliability performance of the power electronics in PV applications will be also be covered in the lecture. 

Prerequisites:

• Basic knowledge of power electronics circuit and electrical engineering
• Basic knowledge of circuit simulation software, e.g., Matlab/Simulink, PLECS

Price:  6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry excl. VAT.
A link for online payment by credit card for externals participants will be annonced after deadline for registration

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 3000 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.
