The course was enjoyable and informative. The lectures were clear and easy to understand. The assignments were challenging but were majorly based on what was explained in the lecture videos. There were a few things that required extra study but it added to the challenge of the course.

The deadlines, however, were very hard to keep up. The assignments required quite a bit of time which was not factored into the hours of study required. That can be a bit misleading.

Also, there wasn't a lot of help available in the discussion forums and the questions often went unanswered which a a big downside especially when it came to doubts and questions.

Overall, the course was good as an introduction and very informative.

Course content was very good and the instructor made it enough simple to understand. Even the quizzes were well-crafted and questions made us to think and understand more. But I am not happy with the way quiz answers are judged, especially the questions where we need to enter an expression. The simplification of an answer differs from person to person and the extent one simplifies an expression is important and unique for the answer which are assigned correct. Most of the times my answers were right but had to juggle them to find the right combination, which took so much time for each question and assignment. If Coursera can do something towards this, it would be much helpful in future.

T​he course gives a good introduction to power electronics. Without a good background in Electrical Engineering, the course is very demanding, and you need to invest a lot of time. The professor explains the most important concepts without going into detail of the mathematical background, which is good for most students.

U​nfortuanteley, I missed the practical aspect, like simulation or hardware design. But I hope to get into this aspect in the more advanced courses in this specialization. Another thing to mention is that there is no communication with the teaching team, and nobody would answer your questions if you got stuck. So, you are on your own.

This introductory course was very difficult, yet well worth the effort in retrospect. The time commitment was vastly underestimated; the last two homework assignments required 8-10 hours of work each. I would have appreciated more relevant example problems directly related to the assignments, which were much more advanced that the lectures. Thankfully I purchased the recommended course textbook, which did help. There were several issues with the web based platform, relating to rounding accuracy and data entry problems. Luckily Coursera allows one to submit as many attempts as possible. Cheers!

Pretty solid course for an online format. Solid grader and I enjoy how you can input derived equations in the homeworks that makes it feel more brick and mortar class. This beats other class approaches I have used in other platforms that use peer grading. Very comprehensible introduction and a satisfying course. I wish the course work was a bit more challenging. I know this is difficult in an online format (1st offering?) but when I compare this homework to their actual class websites (for on-campus students), it is obvious this online format was given the "easier" problems to solve.

I enjoyed the course and I learned a lot from it in spite of the fact I've been designing DC/DC converters for decades. The only reason I with-held one star is because I had a lot of trouble with the quizzes due to the case-sensitivity of the formula answers coupled with the inconsistency of case. For example, in Ch 3, Problem 10, you use use VT for the IGBT saturation voltage and Vd for the diode forward voltage. If you use Vt and/or VD, you get the dreaded giant red X.

Good starter for learning some basics on DC converters. It is helpful to know some undergraduate electrical engineering basics. Background related to diodes and transistors is also helpful.

The material is well presented, but and requires taking good notes. The homework/quiz assignments are very much aligned to the course material, but a couple of questions can be challenging. The assignments can take a bit of time so one needs to plan and not feel rushed through.

Cool course! Took some time to go through the problems and really understand the material, but I feel like it's very useful. My one complaint is there is no correspondence from the professor and there is no answer key, so when an answer is wrong, that's it, you don't know how to solve the problem or understand what you did wrong. I will still continue to take the following sections for the power electronics track on Coursera. Thank you.

It is certainly a very helpful course. The quizzes were very good and not very easy to solve in the first go. My only recommendation would be for the instructor and the Teaching Assistant (if there is any)....please monitor the discussion forums as a lot of students need help with the concepts. Better, appoint more TAs for the course so that they can respond and the instructor can just monitor. Thanks!

The course materials and the topic of interest is fantastic. Dr. Erickson does a great job explaining the fundamentals of power switching technologies and the homework greatly tests a participants knowledge of the subject matter and forces the user to really digest the material. My only critique is I wish the homework solutions would be shared after the homework due dates so that one could learn from
