Three-mode Smooth Switching Control Optimization Method Based on Four-switch Buck-Boost
Conventional operating mode of four-switch Buck-Boost converter is to calculate the duty cycles of Buck,Boost and Buck-Boost modes based on different formulas.This control strategy is relatively complicated,and if the conversion control strategy adjusting these three modes is not designed properly,it will cause fluctuation of output voltage.This pa-per outlines the working principle of Buck-Boost converter,describes the principle of a digital control technology.It then performs mathematical modeling,simulation analysis and experimental verification for the proposed control technology,which achieves experimental results consistent with theoretical analysis.
