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...
The nonlinear dynamics phenomenon of a Power Factor Correction (PFC) boost converter is explored through this paper. A current mode control scheme is chosen for this purpose. The nonlinear behavior of the circuit is experimented through simulation methods. The dynamics of the system is investigated through iterative map techniques. The stability of the system is focused through the selection of the...
This paper describes the complex behaviors (i.e. Chaos and Bifurcation) of flyback converter under peak current-mode control. Firstly, an iterative map based converter model is developed from it's on and off states equations to study these complex dynamics. Then primary bifurcation parameters of converter like reference current, input voltage, load resistance, inductance and output capacitance are...
