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.

The whole specialization series is definitely a 5 star Coursera course. As a electrical engineer designing lab and industrial use power supplies, I found the material in this class review and enhance my knowledge, and more importantly, a systematic view of DC-DC converter concepts, which is a good reference of my future career.

The book those professors wrote is called "bible" in the power electronic industry, and most of the interviewers will ask questions related to the material in that book when you take a job interview in this industry, especially for an entry level or junior position. Watching the videos and doing the homework and final project help me understand those material more efficiently.

I appreciate the great work from all three professors!

Excellent introductory course. The material is presented simply with just the right amount of complexity. Prof. Erickson is an excellent instructor who covers the relevant concepts clearly, concisely, but comprehensively.

My main criticism is how Coursera handles the homework assignments. The homework answers are not saved between consecutive tries; if one makes some mistakes on the first try, then on a new try one has to write all the answers all over again which is cumbersome since there are usually around 15-20 questions where a good amount of answers are algebraic expressions. It would be better if all the answers are saved between tries so one can easily edit wrong answers while not having to write the right answers from the previous try all over again.

It is a nice course. For a change, the quizzes were challenging, which was nice, but inadequate support provided by the mentors and the course forum are disappointing.

I thought this course was an informative introduction to an important class of electronics. The lecturer was easy to follow, except during certain topics. That, however, is more due to the difficult nature of the subject than a fault of the professor. I found myself pausing and rewatching some portions so I could gain a better understanding but I don't have any problems with that. There is a good balance between more generalized overviews of key circuit concepts and more detailed analyses of specific circuit topologies. You may have to do some outside research to fully understand all details and I know some people may be turned off by that. I believe it is fine, and it is a good way to learn how to find information on your own. I did not have to do this more than a few times (that would actually be annoying). Lastly, the assignments were just challenging enough to force me to actually grasp the material, without making it seem like it was impossible to complete.

The course is indeed source of motivation for beginner to delve deeper into the field of Power Electronics. From the course content to the quizzes, and the instructor's excellent way of teaching to the Coursera help and support, everything is commendable, flawless, and captivating to research. After successfully finishing the course, I intend to enroll in its specialization program. Coursera owns means a lot to me, being an intermediate level researcher, grown up in an environment lagging far behind in research in Power Electronics. Thanks Coursera for all such support, and thanks to Prof. Erickson for his untiring efforts he put in arranging and delivering this course. Stay blessed!

Phenomenal Course.

With a background in mechanical engineering and physics, I worried that this course would either assume to much and be too technical or be too easy and superficial. Neither is true; the course introduces topics only assuming basic electronics knowledge but still manages to cover a lot of material and be quite challenging. Dr. Erickson's lectures are clear and focused.

The homeworks are hard but fair (there is a glitch in the first homework that almost convinced me to drop the course, but I'm glad I didn't; the glitch does not appear again and I am hoping they fix the glitch in the future). I encourage anyone interested in power electronics to go through the course.

This course has been very helpful in understanding the principles of dc-dc converters and introduced me to LTspice. I enjoyed every part of the course especially the quizzes and chapter problems.

Phenomenal course. Very well structured and easy to follow. I have gained a deeper understanding of the basics of power electronics converters that have helped me understand these concepts much better at work, so an overall win for me. :-)

I was lucky enough that my mentor was able to lend me the book "Fundamentals of Power Electronics" by Robert Erickson and Dragan Maksimovic. This course follows the first three chapters of the book and vice versa, and so having that book handy proved tremendously useful (but not necessary to finish this course).

Overall, thank you for the lovely course and I'm looking forward to the next one!

This wan an excellent course especially for electrical engineering students.

I suggest this course to every electrical engineering student and anyone interested in Power Electronics.

Good course overall. I thought the homework was actually pretty challenging, but the lecture effectively prepared you to complete them. The estimated complete time for them is horribly incorrect though. I found they took way longer. I wish there was a bit more discussion of theory regarding some of the "small ripple approximation" as it doesn't feel like there is enough justification behind our ability to simplify the math so readily. I also wish there was a more detailed steps shown during circuit analysis and derivation in the lectures. It would certainly help give me more confidence while working through the homework.

Very clear and concise explanations about basic analysis methods for power electronic circuits. What's great is the emphasis on general methodologies - you are not expeted to memorize the operation of all different power electronics circuits but are rather taught generally applicable tools to analyse any power electronic circuits you are given. I have taken this course as a refresher as I previously have a Master's in power electronics but have been working in other industries for the past 5 years. Thus, I think I can confidently say that the coverage in this course is good and the lectures and exercises have clearly been carefully constructed. My only minor negative point is that the exercises, while generally very good for making the student apply the skills taught in the course, are a little bit unforgiving in the sense that if you have somewhere along the way made a mistake when deriving analytical expressions, it might be quite difficult and time-consuming to find the error as it is difficult to get hints or to get pointed in the right direction. Of course, that might be expected from an online course and I guess there is also a (more expensive) version of this course available where you also have access to course staff which would certainly help when running into such issues. It's quite a time-consuming course so be prepared, I spent much more than the quoted 3h per exercise (without counting the first exercise which was pretty straightforward).

Teaches the basics of buck and boost converters (switching voltage regulators). Basics like how the switching duty-cycle determines the output voltage, and how the essential components affect ripple in the voltage and current.

The homework assignments are challenging and meaningful without being enormous undertakings.

Assumes freshman or sophomore-level electronics engineering knowledge (or maybe the first chapter of The Art of Electronics). Assumes familiarity with the basic concepts of calculus (what derivatives and integrals are). Homework requires some algebra (algebraic manipulation) but no difficult calculus sort of algebra. Homework does require thinking outside of the box a bit; the solutions to some problems are not completely obvious from the lectures.

The subject material is very well organized. Prof Bob Erickson explains the subject in a way that makes it simple and intuitive to understand the concept. It's such a welcome change from a 'push the book material' style of the most. The HW and Assignment questions are extremely well designed. They make the students to go through 'nooks and corners' of the subject. My only unfulfilled wish from the course is live demos with real life components and explanation of their relative merits over others. A 'virtual power electronics lab' to this course will be a welcome addendum.

A gratifying experience to receive the certificate signed by Dr Robert Erickson!

Well laid out review of the math behind switching converter designs. Course provides some above and beyond material (ie an example of a MOSFET driving circuit) for those looking to learn more.

Only negative comment I have is regarding the forums. The moderators appear to be semi-active and answers conclusively, but it has pages on pages of people asking the same questions, so sometimes it's hard to find the right discussion. Highly recommend the moderator 'closes' similar questions and refer's the author via link or something to the full discussion on that question wherever it is.

This was one of the best course that I came across online. I have studied this course during my undergraduate program but the way this course was handled and taught here was amazing. I learnt about many new methods of analysis of a converter. Moreover I learnt about the converters concepts in a way that I had never learnt before. Overall It was one of the best experience and I would recommend to every person interested in this subject to take this course. Thank you very much for giving me the opportunity to be a part of this community.

Fantastic introductory course to a long awaited specialization. I'm an electrical engineer and I was related to most of the theory prof. Erickson discussed with us in the lectures, but assignments, quick questions and facts were beyond my expectations. I can actually say I learnt things in these few weeks. And is just the beginning. Can't wait until we get to the control loop design for active filtering techniques. Great job by prof. Erickson and his team for the resources and the knowledge.
