Chaotic behavior of DC-DC converters

This paper presents an investigation of the chaotic behavior of power electronic converters. The DC-DC converters are highly nonlinear devices. The switches and passive components make the behavior of these converters difficult to be characterized with the conventional analytical tools. Therefore, investigating modeling methods and analysis is necessary. Knowing the behavior of these converters allows improvement in the electromagnetic compatibility of the power supply, and enhances converter design process. Several tools to investigate the behavior of the converters are illustrated, such as bifurcation diagrams and Poincare maps. SIMULINK model is provided to illustrated chaos and bifurcation phenomena.
