Study on Entropy Characteristics of Buck-Boost Converter with Switched Capacitor Network
Switched capacitor network has been widely used in power electronic circuits. Under the same input voltage and switch duty cycle, buck-boost converter with switched capacitor network can achieve better voltage-drop effect. Based on peak current controlled buck-boost converter with switched capacitor network, a model of discrete iterative mapping, 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.
