This course can also be taken for academic credit as ECEA 5702, part of CU Boulder’s Master of Science in Electrical Engineering degree.

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.

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.

Along with the asymptotic bode plot it could have been nice if bode plot thru simulation could have been introduced with the help of Matlab/python (preferably python, as its open source tool)

very well designed course content with a very eloquent explanation of Dr. Erickson. Highly recommended for power electronics engineers!!

Very interesting way of looking at ac circuit analysis from a graphical perspective. Makes visualizing the ac variations in switch mode power supplies less complex.
