課程概述

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.

WOOO .. This course is great ,, with the quiz in between the video lectures makes learning fun.

the home work problems are also great to work. More emphasis laid on the simulations results to be read correctly and reflecting those results onto the solution for the home work problems...

still looking forward more to learn and simulate.....

I have taken this course live in my university, but the messy way it was taught created so much confusion. Now, it's all being cleared up. I really appreciate the slow pace the course is taking and the way that difficult matter is easily explained by the professor. I am looking forward to taking other courses in the Specialization.

Professor Erickson explains both the mathematical and physical definitions of all converter equations. His methods enable you to tackle more complicated problems while maintaining a physical insight (not just playing with the math). Very good derivation of how to include losses and calculate the efficiency of a dc-dc converter.

This course allowed me to read widely to fully understand. It was intellectually stimulating. I, however, feel for a course entitled "Introduction to Power Electronics", it was quite advanced. It is part of a masters' course so I guess the definition of "beginner level" is quite different. I give it my full thumbs up

Very interesting and challenging, you will need to dedicate a couple additional hours to the ones suggested in order to complete the homeworks. I would recommend the use of Mathcad or similar software to solve equations once you have the hold of it, it will save you a lot of time that you could use for design.

The Course is excellent, it covered various aspects involved in Modeling of DC Converter Circuits and computing their losses. Prof Erickson taught this course very well. I am very thankful to University of Colorado, Boulder for this course and Coursera for Creating such a wonderful platform.

A very good introduction to the concepts of power electronics. Having a background in physics II (Freshman level 2 and/or Electromagnetic physics) is about all you need. I would recommend a firm grasp on Kirchoff's laws and listening closely to the professor. He is very good at what he does.

I really enjoyed learning this course and it helped me understand and analyse circuits better. The teachings go hand in hand with the prescribed textbook. The home assignments were challenging and helped improve my knowledge of this course. The introduction to Spice was also very helpful.

The course is very good, but would like to make three suggestions:

1) You don't have a feedback from what you made wrong in the exercises. It is usefull to learn from the mistakes.

2) One week is a short lead time for the tasks

3)It might include extra optional tasks regarding simulation

Very straightforward. Professor Erickson's approach avoids to overcomplicate the subject by making a very logical analysis of the models, introducing the student in bussiness with ease. No complex math or super-complicated equation systems. It's just clean, simple and conceptual.

The course is challenging but it really gives a great introduction into the basics of how switching converters work. The lectures are clear and the book is helpful. A solid understanding of circuit analysis definitely is needed for analyzing the circuits. Great course overall.

This course is really good for solidifying the basic analysis and derivations. I have over 10 years of DC/DC industry experience but taking this introductory course I was still able to learn valuable information and was able to brush up on many areas of converter analysis.

Instruction was very clear and supplemental lectures with discussion forums were sufficient to complete understanding. As suggested by instructor, the most benefit came from repeating coursework until completion. This brought to light points of misunderstanding. Great!

The BEST online course I attended so far. Learned a lot. Videos are short but had more information. Assignments are quiet easy if we learn from the video well. I completed this course with Financial aid. Thanks to Coursera. Looking forward to next course.

Some questions of the quizes was very time consuming because of the tight numerical tolerances. To find the exact value I had to make so much calculus. Except that, I enjoyed very much with this course. Thank you very much to the Professor and the staff.

Course gives introductory insight into analysis of DC-DC power converters, which can be extended to converters of any complexity. Dr. Ericksen has explained these concepts well and the assignments further enhance one's understanding of the subject.

it is a great introduction to steady state behavioral modeling. You need some previous knowledge of Power Electronics to help you, but the steady state modeling is something I hadn't really practiced much since college so it was a nice refresher.

Great course. The conceptual aspects were covered really well and sets up the student for increasing level of complexity in the weeks ahead and the courses later in the specialization. Looking forward to the next course in the specialization.

This course provides a great introduction to the field of power electronics. The difficulty level is moderate and the course is well paced. This course only provides an insight into DC-DC converters using just the basics of circuit theory.

My first completed module in Coursera. It means a lot. I have also been given the aid to complete this module. This course is short, yet challenging. I would like to complete the whole specialization within 6 months. Thanks to the team.
