An analytical discrete model for evaluation the chaotic behavior of buck converter under current control mode

This paper presents the chaotic behavior of buck converter for switching courses in current control mode by discrete equations. This behavior is demonstrated by presenting a piecewise linear discrete map for this converter and then combining the feedback equation to obtain the overall equation of the converter. After obtaining the overall equation, exact map behavior is then studied. For this purpose, the transition path to chaotic behavior, discrete chaotic time signals, and bifurcation diagram circuit are presented in different conditions, based on various circuit control parameters.
