À propos du cours

This course can also be taken for academic credit as ECEA 5701, part of CU Boulder’s Master of Science in Electrical Engineering degree. This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained. Power diodes, power MOSFETs, and IGBTs are explained, along with the origins of their switching times. Equivalent circuit models are refined to include the effects of switching loss. The discontinuous conduction mode is described and analyzed. A number of well-known converter circuit topologies are explored, including those with transformer isolation. The homework assignments include a boost converter and an H-bridge inverter used in a grid-interfaced solar inverter system, as well as transformer-isolated forward and flyback converters. After completing this course, you will: ● Understand how to implement the power semiconductor devices in a switching converter ● Understand the origins of the discontinuous conduction mode and be able to solve converters operating in DCM ● Understand the basic dc-dc converter and dc-ac inverter circuits ● Understand how to implement transformer isolation in a dc-dc converter, including the popular forward and flyback converter topologies Completion of the first course Introduction to Power Electronics is the assumed prerequisite for this course....

A really good course on converter circuits. The way Dr. Erickson synthesized inverters from buck converters was eye opening. Many lectures overlook such basic aspects of power electronics synthesis.

The course has intensified my interest towards the field of Power Electronics. One won't find such systematic and lucid teaching anywhere else. I am grateful to the instructors of the course.

Good stuff here, Homework really have you thinking.

Lots of pros & cons:

Math formulas are either wrong or right, no partial credits. So, you could actually have the correct answer on paper but its not inputted how the website would detect it then its graded as incorrect.

Good news is you get multiple re-sits.... bad news is if you have a concept wrong and/or input is incorrect then the re-sits are of no use until you figure out the typo or whats wrong with your reasoning.

Bad news - understanding is limited to what the video says, no matter how many times you repeat it. Good news, supplemental reading on google is fair enough to help you get over most hurdles.

Bad news - some homework questions aren't exactly straightforward from the notes.... but, SUCH IS LIFE. Its the same as you local college so dig in and go figure it out, somehow and make use of the re-sits.

Overall, good job. I have learnt a lot and hope I can make it to the end. Looking forward to the design project, nothing beats putting it to life in a "real world application" after torturing with so many formulas and theories.

Course 2, Converter Circuits, is as interesting as was Course 1. You can stop, have a rest and retake the course. The work load varies from week to week. You learn the famous converter flyback and forward.

Course 1 is enough if you just want to know what a converter is. But for a real knowledge, I think one must do the other courses of the power electronics specialization, that is to say course 3, 4, 5 and 6. Still a lot of work to come!

Excellent way to understand the power converters and its relation

most liked topic was -interchange of load and source and realize a converter out of it

but for the flyback and forward it was touch disappointing the lecture did not go well as expected

we need more details in solving the volt-sec balance and charge balance for both converters in detail

Very good, but some topics may need to be explained further, like the realization of the switches

Honestly, the assignments are unnecessarily cumbersome. As an EE student in university, I have learned some contents of power electronics in my own Syllabus, and found this course a good review as well as a source of insights. For a pure enthusiast, I guess this course will be somehow difficult and hard to fully enjoy.

Great for applied technology on low power DC/DC converters

This course is very difficult, particularly in week 4. The single sample problem with solution provided is utterly useless in helping you prepare for the assessment. It does not parallel the material covered in the lessons and does not prepare you for the assessment. It's bizarre to me that there aren't at least 5 practice problems with solutions that help you prepare for the assessment. Having this is critical to taking an online class by yourself, since the forum cannot be relied upon for timely help, if at all.
