Buck Converter with Impulse Resp. Analysis
This demonstration shows how to perform a Steady-State Analysis and obtain different open-loop transfer functions using Impulse Response Analysis for an unregulated buck converter with a resistive load. For detailed information see this tutorial.
A demonstration of a Loop Gain Analysis is given in the demo model Buck Converter with Loop Gain Analysis.


To run an Impulse Response Analysis double-click on the Impulse Response Analysis block to open the dialog and click on the Start analysis button. The progress of the analysis is displayed in the MATLAB Command Window. When the analysis has finished a new Bode plot will be displayed showing the corresponding transfer function.
