Buck Converter with Multitone Analysis
This demonstration shows how to obtain different open-loop transfer functions using Multitone Analysis for an unregulated buck converter with a resistive load. For detailed information see this tutorial.


To run a Multitone Analysis double-click on the Multitone 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.
A demonstration of a Loop Gain Multitone Analysis is given in the demo model Buck Converter with Loop Gain Multitone Analysis.
