| Abstract: | Instability phenomenon such as chaos and bifurcation often appears during the design of power supply controller based on small-signal model. In this paper, an average current Boost PFC circuit model was setup from a view of engineer design, and the nonlinear instability phenomenon existed in this system was analyzed. This design was prepared for establishing the model of whole circuit and for the further analysis. Nonlinear phenomenon by theoretic analysis is also described based on bifurcation and chaos theory. |
