Recently, power factor correction (PFC) boost converters have been reported as exhibiting a wide range of bifurcations and chaos under specific conditions. In this paper, we derived a nonlinear model from one point of observation to the next. Analysis of this model shows that chaos and bifurcations may occur along with the changing values of some system parameters. A current-mode controlled PFC boost converter in chaotic behavior is chosen as an application example. A numerical simulation using MATLAB confirms the predicted bifurcations. Finally, a blockset model using Simulink/Matlab is designed to conclude the validity of the numerical simulation.
