摘要
Abstract
The current-mode controlled switched-inductor Buck-Boost converter was chosen as the research object. Through numerical simulation,the bifurcation diagram,the Poincare section diagram,the largest Lyapunov exponent and the Jacobian matrix eigenvalue of this circuit system were shown here. The switched-inductor Buck-Boost converter circuit system nonlinear behavior and the case of chaos were analyzed ,and stability criterion of circuit system was deduced. For the first time,the parametric perturbation method was applied to control the nonlinear behavior in switched-inductor Buck-Boost converter. At the same time,pertubation amplitude and pertubation phase angle were calculated. Finally,the corresponding Matlab/Simulink simulation and experimental circuit validation were done. The result shows that the chaos of the circuit system can be reduced efficiently by the parametric perturbation method.关键词
