My opinion:

Not much monitoring of the forums by mentors\instructors, hence responses are non- existent\delayed\misleading. some of the replies by mentors were misleading, The rationale of the Volt-sec balance was not set out very clearly, The expression evaluator is very temperamental, i had to enter the expressions many times , a very time-consuming & frustrating process.

This Course is very standard. I would have given 5 stars. Once you complete the weekly quiz and PASS it, you don't see the worked out solutions for the weekly quiz so that you can review.

Good Intro information,but very little interactions or none on the discussion boards as the hw assignments are too complicated next to the lectures.

Quite good course practical and useful but without any support of lecturer or responsible person who is able to answer specific question at forum

More theoretical. Analytical and Intuition is not much developed. Good for getting familiar with switch mode converter circuits.

There are serious issues with the quizzes. Other than grading correct/incorrect, there is no feedback afterwards.

Should be extended from 3 week course to 5 week. Basics should be covered in 1st 2 weeks

That course is quite good to get the fundamental knowledge about power electronics

Course is very good and well explaned. Tutor support is very patchy though.

Good course. How to get feedback about homework?

need assistance of teachers

Innovative & very tough.

give me my certificate

it was help full

BIT DIFFICULT

LTSpice is what spoiled it for me. It made it impossible for me to continue this course past week one due to the demands of the workings of my work and budget. I am running a farm on a shoestring budget as my semiretirement profession, and the expense of getting graded by the LTSpice made this unfeasible for me.

No TA/Professor help. Some of the HW questions were ambiguous. Posting on the forums didn't help at all, no one is there.

Its Not an introduction , its from intermediate level
