Abstract :
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 varied to investigate the converter dynamics. According to quantitative increasing or decreasing of these bifurcation parameters the logistic behavior of converter has been attained fundamental periodic oscillation to chaotic oscillation through period-doubling bifurcation. The iterative map based model of converter is simulated and the changes of the converter dynamics with variation of primary bifurcation parameters have been reported in this paper.
