A buck-boost circuit is rich in nonlinear dynamics. Its operation is characterized by cyclic switching of circuit topologies, which gives rise to a variety of nonlinear, such as subharmonics, bifurcation and chaos. Based on PSPICE, the period-doubling phenomena exhibited by a current-programmed DC/DC buck-boost switching converter are studied. Furthermore, the system model and the iterative map of the converter are derived to explain the nonlinear phenomena. Based on MATLAB, the numerical simulation with this iterative map has led to the bifurcation diagram.
