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.

By 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.
