We present a numerical study of an example of piecewise linear systems that constitute a class of hybrid systems. Precisely, we study the chaotic dynamics of the voltage-mode controlled buck converter circuit in an open loop. By considering the voltage input as a bifurcation parameter, we observe that the obtained simulations show that the buck converter is prone to have subharmonic behavior and chaos. We also present the corresponding bifurcation diagram. Our modeling techniques are based on the new French native modeler and simulator for hybrid systems called Scicos (Scilab connected object simulator) which is a Scilab (scientific laboratory) package. The followed approach takes into account the hybrid nature of the circuit.

Sufficient And Necessary Condition

In this paper, the model of Buck Converter in DCM is built based on the theories of Hybrid Systems and Switched Linear Systems firstly. Then the output controllability of Buck Converter is studied and its sufficient and necessary condition is given. In the end, the simulation analysis and verification are provided. The research results indicate that the output of Buck Converter can be stabilized at the setting value when the condition of output controllability is satisfied, on the contrary, the output can't be controlled stably.
