Complex Dynamic Phenomena in Power Converters: Bifurcation Analysis and Chaotic Behavior
نویسندگان
چکیده
– In recent years it has been observed that some power converters can exhibit deterministic chaos. Since converters have wide industrial applications, it is useful to study their bifurcation phenomena in order to understand the change of behaviors as circuit parameters are varied. Therefore this paper aims to investigate some complex dynamic phenomena that can occur in currentprogrammed DC-DC boost converters. To this purpose, the paper illustrates bifurcation analyses as well as new possible pathways through which the converter may enter chaos. In particular, based on PSpice design, it is shown that variations of supply voltage and inductance generate interesting bifurcations and novel routes to chaos. Key-Words: Bifurcation, chaos, DC-DC converter, PSpice design of switching circuit.

متن کاملChaotic Response and Bifurcation Analysis of a Timoshenko Beam with Backlash Support Subjected to Moving Masses
A simply supported Timoshenko beam with an intermediate backlash is considered. The beam equations of motion are obtained based on the Timoshenko beam theory by including the dynamic effect of a moving mass travelling along the vibrating path. The equations of motion are discretized by using the assumed modes technique and solved using the Runge–Kutta method. The analysis methods employed in...
