About the Course

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.

Information taught in lectures was great. However, I feel the homework grading method could be improved. Since we get unlimited attempts, I wish our correct answers would be saved so we don't have to re-enter them during our second attempt. Maybe instead of having the submit button turn-in all answers, there can be a submit button for each individual question to lock in the answer.

I found the course to be very well presented and structured. Focused content on key principles and techniques, with good reinforcement homework problems. I especially appreciate the auto-grading with allowable retries - the most learning was from correcting my mistakes. I only wish solutions were available for all of the textbook problems, not just some of them.

Well done in terms of mathematical rigor and explaining the basics. One critique that I have is that there isn't enough time spent on intuition around the circuits. For instance, how does the buck converter work from a more qualitative standpoint? Easy to look up online, I understand, but the professor is excellent and I would benefit from his perspective.

Explanation of the operation of DC converters was much more intuitive than anything I have seen thus far. The examples presented are practical, with tangible real world applications. The only item that could use improvement is the ability to see worked out solutions for incorrect quiz or homework items after the class is finished.

Thank You for such a wonderful courses. This courses is good , knowledgeable , good explanation. I learned new concept from this course. From this courses i came to know that what all things I need to brushup for my master's degree. Assignment is a bit difficult and over all stuff is good . Thank you so much.

the solution for numerical question were hard because of .1 % barrier and . the answer once entered correct the database should keep that result to reduce re entry of correct answers. add more exmple so that student can do more practice before attending assignment.

Excellent introduction to the analysis of switched systems. The explanations and examples are very clearly explained.

The only drawback to this course is that it takes a lot of trying around to get used to enter the formulas into the system for the homework

It is really a nice course, the quizzes were challenging, which was nice, but it would been more helpful if proper support were provided by the mentors when someone gets stuck in a problem and the course forum are disappointing.

I would like to receive feedback about my wrong answers after I approve the course. I really would like to know what were the correct answers.

I think that this is really important because I can learn of my mistakes.

its a wonderful course, full of knowledge

it is great to work it side by side with the book by Dr. Erickson

I have had some trouble solving the assignments, but I managed and it feels so great to finish

This course was quite easy.

The exercises are interesting, given with their full solution.

I think your need Pr. Erickson's book to follow the course.

Thanks to the University of Colorado Boulder.

G​reat course with plenty of information and thorough explanation , but tolerances can be loosen a little bit and more guidance can be provided for the quizes to better guide us through them

Covers all basics required for steady-state analysis of converters.

Could have been better if they provided a solution manual for the assignments and lived interaction with the professor.

The course is outstanding and designed in a very professional manner. This course can be made more better for students by including answers of problems and making forum more responsive.

Homework were tedius. Even if you knew the course subject, it is very easy to make mistakes on numerical questions. I think you should increase the 0.1% error margin to a higher value.

It was a bit too hard.

I wish it had more simulations and practices with software.

Most of the assignments I had to use the simulator to have a better understanding of the subjects.

It would have been better if there was an option to discuss the assignments after submission. I found the discussion forum less useful.

But overall the course was really helpful.

A good introduction to switching converters. There are thoroughly worked out examples to make the coursework accessible to students who are willing to put in the time.

It would be nice to have a way to interact even for a limited amount of time with the professor but I assume that for the cost of the training this is hardly possible

I feel like the lecture should of went over the buck-boost and left the buck converter and the boost converter as homework problems. It was challenging, but passable.

The course was good and the assignments were brainstorming. But if we would have the solution for the wrong answers it would be good. We will get to know the mistake.

It is exciting and meant for people who are interested to research much more about what is thought. May take some time for classmates to help you with any queries.

I do not know... maybe too dry of a course? Info is great, but it seems like the book is a prerequisit.. Otherwise, I got a lot of knowledge, so I am happy

This is really a great introduction to power electronics. The only thing I disliked was you need to type in your answers accurate up to 8 decimal digits.
