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-l 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 Iyapunov exponent for different slopes is

reviewed and simulated
