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
By Milind R•
Very interesting topics, nice analysis. However, the idea of using current-balance into a transformer when not explicitly using AC should have been better explained, it kept going against my instincts to try a full time-domain solution with differential equations. The last week (week 4) contents were also pretty difficult.
By Kaushik M•
The lectures were decent. Assignments were good and interesting to solve. But the only gripe about assignments is that mathematical analysis is way too lengthy at some places as well as I feel (though very few) answers fed to the computer were incorrect. Overall, a decent course
By ABDON T O•
Very good training, addressing the main DC/DC converter topologies, including transformer isolation. I would have liked the switch realization section to be shorter; but other than that, it was really useful.

Very good, but some topics may need to be explained further, like the realization of the switches
By Aleena A•
Quite tough a chapter and module but if you understand the concepts its easy to do !
By ANSHUMAN S•
the last assignment solutions should be provided, rest was good.
By Jairo Z•
The last questionary is a little bit difficult

I wish we had more LTSpice experiments

Difficult, but useful and fulfilling.

The course is challenging for people without electrical engineering background as noted in the course prerequisite. A review of circuits is advisable, if you have not touched on the basics for a while.
I strongly advise to keep good notes, including homework/quiz assignments. They help as reference as you move through the course.
The course material and homework assignments could be better aligned. This is after all not a university level course, so I think it should not create situations where you have to spend a lot of time researching information outside the course material. I had to invest significantly more time then shown in the Course time estimates.
If you plan to take all courses in the specialisation, investing in the Dr Erickson's text book is not a bad idea, but is not an absolute must.
But if you get through, there is definitely a sense of accomplishment and I personally feel satisfied with the knowledge gained as an introduction to converter circuits.

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
By Taylor S•
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.

some of the equations which needs to be answered in Homework is very complex, almost impossible to find the mistakes, even if one is right on the track.
