Abstract

Abstract: To study on the nonlinear characteristics of the Buck-Boost converter in pulse input voltage, the nonlinear model with discrete and iterative was deduced, and the bifurcation and chaos diagram that reflected the output voltage of the converter changes with the inductance, capacitance and resistance respectively was obtained, which analyzed the bifurcate and chaotic phenomena of the converter, and at the same time, compared with that in the DC input voltage. The results show that, in a steady state the variation range of bifurcation parameter of the converter in the pulse input voltage is smaller and is earlier to get into the chaotic state than that in the DC input voltage, which are of great significance for the steady operation of the Buck-Boost converter and its chaos control.
