Study of Bifurcation and Chaos in the Current-Mode Controlled Buck-Boost DC-DC Converter (I) ——Modeling and Simulation

This paper studies the bifurcation and chaos in current_mode controlled Buck_Boost converter. The discrete model for Buck_Boost converter in continuous conduction mode (CCM) is derived. The bifurcation and chaos phenomena of Buck_Boost converter have been investigated with input voltage E, reference current I ref , resistor R, inductor L and capacitor C as bifurcation parameters.
