Nonlinear Dynamic Research of Buck converter Based on Multiscale entropy
The multiscale entropy is proposed to analyze the nonlinear dynamic characteristic of the discontinuous current mode Buck converter in this paper.Firstly,the iterative mapping function of the discontinuous inductor current mode Buck converter is provided; then,the discrete time series of the switching converter is obtained through symbolic dynamic theory,and information entropy theory is used to analysis the symbolic series of the Buck converter; finally,the chaos character of the discontinuous inductor current mode Buck switching converter is obtained by contrastive analysis,and the analysis result would be provide theoretical support for the analysis and design of the switching converter.
