Feedback on Evaluations There were 4 quizzes and endsem. Questions were hard and checking was also hard.

Study Material and References Sir did not refer to any particular book. Content was from different sources. Some text book references are available on ASC.

Final Takeaways Course mostly focuses on applications. If you are good at power electronics then you this course will teach you how to apply previous knowledge. This course is one step advance than basic courses. Content of course is really good and helpful while doing advance projects. You will get to know some of the new concept and research going in Power electronics. Finally course is good if your basics are good.
