Study on Entropy Characteristics of Buck-Boost Converter with Switched Capacitor Network

EasyChair Preprint no. 5502

Abstract

Switched capacitor network has been widely used  in power electronic circuits. buck-boost converter with switched  capacitor network can achieve better voltage-drop effect under the same input voltage and switch duty cycle. Based on discrete  iterative mapping model of peak current controlled buck-boost  converter with switched capacitor network, this paper studies the entropy characteristics to analyze the nonlinear dynamic behavior of the converter. First, two-dimensional entropy of the converter is obtained, which reflects the overall statistical characteristics. Then, the numerical sequence distributions of buck-boost converter with switching capacitor network are also analyzed under different load resistors. Finally, the nonlinear dynamical analysis for the converter is verified by experimental results.

Keyphrases: buck-boost converter, Entropy, nonlinear dynamic, switched capacitor network
