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....

The analysis and materials of this course are very useful. A great section. If the MATLAB script for calculating the converter Poles and Zeros can be provided will be even better.

por KSMar 6th 2018

This is the important part of converters to learn.It shows how much complex the systems will be and shows how can we minimize complexity by taking approximations.
