Abstract

Constant-on time voltage feedback controlled Buck converter is one kind of typical nonlinear system. It produces unstable behavior in the running of the system. With the change of output electric capacity ESR, bifurcation and chaos behaviors are shown in the system. The mechanism that produced the phenomenon is analyzed by using the Floquet theory and stabilization method to control the instabilities of the converter is proposed as well. Analysis shows that the method widens the stability boundary of Buck converter and is in favor of the system steady running. The simulation result proves that the accuracy of theoretical analysis.
