Description: The present article provides an alysis 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-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
