An analysis of power-factor-correction boost converter's nonlinear dynamics through bifurcation diagrams

Abstract

This paper reflects the study of a Power-Factor-Correction (PFC) boost converter's nonlinearity. A peak current controlled boost converter is simulated in continuous conduction mode (CCM) to study the dynamics through the bifurcation diagrams. The study shows that with changes of certain parameters the bifurcation and chaotic state may occur. The bifurcation diagrams indicate the stable zone of various parameters of the circuit which is desired to be selected. The bifurcation map is obtained by varying input voltage and reference current as variable. Discrete state space has also been considered for observing the periodicities of state variables and detecting the route to chaos.
