Abstract

The present article provides an analysis of complex dynamics displayed by current mode controlled switching dc-dc converter. Current-mode controlled boost converter has been studied with nonlinear analysis and the discrete-time modeling approach has been used. By changing circuit parameters, complex behaviors like chaos and bifurcation occur in the switching dc-dc converter. For increasing stable period-1 operation range, the ramp compensation approach has been used and by changing its slope, its effect in the converter will be shown. Finally, the largest average lyapunov exponent for different slopes is reviewed and simulated.
