À propos du cours

This course can also be taken for academic credit as ECEA 5700, part of CU Boulder’s Master of Science in Electrical Engineering degree. This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are introduced, and are developed for finding the steady state voltages, current, and efficiency of power converters. Assignments include simulation of a dc-dc converter, analysis of an inverting dc-dc converter, and modeling and efficiency analysis of an electric vehicle system and of a USB power regulator. After completing this course, you will: ● Understand what a switched-mode converter is and its basic operating principles ● Be able to solve for the steady-state voltages and currents of step-down, step-up, inverting, and other power converters ● Know how to derive an averaged equivalent circuit model and solve for the converter efficiency A basic understanding of electrical circuit analysis is an assumed prerequisite for this course....

This course sets the groundwork for more advanced concepts in Power Electronics. The Professor was very explicit and the homework assignments were of a good strength to help ground the notions learnt.

Very nice course. Even if you are already familiar with power electronics, it will help you to form a system of knowledge and utilize rational approaches for task solution of any level of complicity.

I haven taken power electronics in both undergrad and grad school, and did several online courses on EDx, and I am not impressed by this course. If I had to learn these first principles from this course, I would be suffering pretty bad. The lecturer is jumping back and forth between topics, not building the necessary mental structures. The lecturer lets power point do the teaching, then occasionally he tries to derive things in the corner, which is very hasty. He should just take the time and write out every equation so that students have a chance to follow and repeat real-time. (Nobody will interpret 4 long equations suddenly appearing in front of them + the important details easily slide away!) The length of the course is misleading, if you spend only a few hours with it, you can definitely pass, but you won't get the full picture, especially not enough if you ever want to work in this sector. I strongly advise to work out all the practice problems before the homework for practice.

This course has some very good things to learn. It picks up pace very rapidly. My biggest complaint is that there is far, far too few examples and/or sample problems. There are none in the lecture, and only 2 solved sample problems per week. There is no point in giving 7 sample problems, then only giving the solution to 2 of them. The lectures are good and coherent, but I don't feel like they fully prepare you for the homework, particularly for Week 3. And the forums are not very helpful for diagnosing mistakes, in the rare event you get an answer in a timely enough manner to be helpful. All things considered, I learned quite a lot from the 3 weeks of this class and is still a bargain for the price.

Although this course was great overall, I think it needs to have more content to explain more converter topologies. The homework assignments were at times extremely difficult due to a lack of helpful examples in lectures.

I have taken this course in undergrad (RIT) and concepts were more thoroughly explained to me there than here. I hope I am not being too harsh, as I do think this is good for those that haven't been exposed to much of the power electronics field before. Maybe the next course in this specialization will change my opinion!

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.

A good course but need some more advance software for the solving and practising of assignment and knowledge.

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

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
