Bifurcation and chaos of DC-DC converter as applied to micro-inverter with multi control parameters

In general, DC-DC converter is a highly nonlinear system. More than one decade ago, many researchers have approved that DC-DC converters are experiencing bifurcation and chaotic oscillations. In this paper, both DC-DC Buck and Boost converters are been studied and analyzed. The study showed that such DC-DC converters are experiencing a nonlinear behavior (chaotic behavior) under certain operation conditions. In this paper, we studied the bifurcation and chaos in the DC-DC buck converter with changing different control parameters. In addition, the bifurcation theory will be applied to DC-DC Boost converter. Bifurcation diagrams and state-space diagrams have been shown for changing some control parameters.
