The course evaluation report is based on personal feedback received from the students. For the first time ever, the ET8303 PhD course has gone through a re-organization. In particular, the course was redesigned comprising several modules. Each module focuses on an individual research/scientific theme in the field of power electronics, power semiconductors, reliability of power electronics, design of magnetic components, thermal design of converters etc. Following this module-based structure, the flexibility of attending the course is enhanced, while it allows for individual module development and research-based educational material by integrating research findings on a continuous basis. Students found this PhD course very interesting, important for their research on power electronics, control of power converters and modelling. Students also appreciated the guest lectures from international lecturers. However, the main challenge imposed by the COVID-19 restrictions was the completely digital course teaching for Spring 2021. Hopefully, next round of the course will be taught physically, which will also allow the use of interactive means of educations, such as student response systems for monitoring the class dynamics. All in all, on a personal note, I feel that the flow of the course was very smooth and the course preparation (e.g. slides, material, problems) was less demanding compared to the first term. My priority is to continuously improve the teaching style, quality of learning methods, course materials and to establish interaction with the students in the class. Referring to PhD students’ engagement with the lecture, I found it less difficult compared to the TET4190 course, because we are well integrated with the PhD students of our department and we had known each other prior to the course start.

The intended learning outcome of the ET8303 PhD course is dynamic and well adapted to the needs of the PhD students in their research projects. Thus, my intention is to update the course material every term the course is offered. Recent research findings from my research team's work have been integrated to the curriculum of the course in a way that complement the core intended knowledge to the students. At the beginning of each lecture, the students are informed about the learning outcomes of the specific lecture. I usually present a list of intended learning outcomes and analyses them briefly, so that the students will be aware of the most crucial and important parts of that lecture. The general learning outcome of the course is presented during the first lecture and it is briefly analyzed by the tutor.

The teaching activities for Spring 2021 contained:<ul><li>Lectures</li><li>Presentations from the students on relevant topics to their research</li><li>Invited lectures from professors from Xi'an Jiaotong University in China (in the Fram of the INTPART CoNeCt project) </li></ul>

In the ET8303 PhD course the assessment form contains a final written report, presentation of the projects and an oral exam. The final grades are either Pass or Fail. For Spring 2021 semester, all students have passed the course.
