About the content

This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations. These models are then solved, to find the important transfer functions of the converter and its regulator system. Finally, the feedback loop is modeled, analyzed, and designed to meet requirements such as output regulation, bandwidth and transient response, and rejection of disturbances. Upon completion of this course, you will be able to design and analyze the feedback systems of switching regulators. This course assumes prior completion of courses Introduction to Power Electronics and Converter Circuits.

Syllabus

  • Week 1 - Ch 7: AC Equivalent Circuit Modeling
    How to extend the converter steady-state equivalent circuits, derived in the previous courses, to obtain small-signal ac equivalent circuits that model the important converter and regulator system dynamics.
  • Week 2 - Ch 8: Converter Transfer Functions - Part 1
    A review of the construction of Bode plots of the magnitude and phase of first-order, second-order, and higher-order transfer functions, with emphasis on techniques needed for design of regulator systems. Design-oriented analysis techniques to make approximati...
  • Week 3 - Ch 8: Converter Transfer Functions - Part 2
    Design-oriented analysis techniques to make approximations and gain insight into how to design ac systems having significant complexity. Graphical construction techniques.
  • Week 4 - Ch 9: Controller Design
    Application of the material of Chapters 7 and 8 to design closed-loop regulators that employ switching converters. How to design a feedback system that accurately regulates its output while rejecting disturbances.

Professor Erickson is really good in classical control. In a world where Bode plots are considered obsolete dinosaurs, he extracts so much info from these "old-fashioned" tools and offers deep insight and quick practical solutions

I spent enormous amount of time figuring out some assignment questions. Hope the idea of these practices makes sense in the industry.

The course made me loose the forest for the trees. The next course Advanced Converter Control relied heavily on this course. Even though I got a 100% grade on this course, I couldn't map its teachings to the next course which basically required the application of Converter Control techniques.The method of presenting concepts is not streamlined in this course. It is often the case that while discussing a main concept, the course branches off to some secondary concept and ends up spending majority time there. The over all impression one gets is that the secondary concept is the main concept and this leads to confusing the bigger picture.If only engineering instruction could be made more intuitive, life would be much easier.Having said the above, I am immensely helpful that the instructor presented this material in an online platform. Yes, I found the content confusing and frustrating, but it made me aware of field of converter control and its main components. Had this course not being offered online, I would never had the chance to learn about converter control. For this, I am indebt to the instructor. Thank you!

the learning material is very much and it is tough to get through the homeworks.Expecially weeks 1 and 2 are mixed which makes it difficult to solve the first homework. As soon as you watch the first lectures of week 2, you wonder why that wasn't tought in the lectures of week 1.Nevertheless, I still like the course and keep getting progress although I nearly have no preknowledge about the topic. I use the course to get some basic knowledge about this topic

One of the best courses I've ever taken. It was not so easy to follow, which made me review some topics of my Engineering course.
