Abstract:
Power electronics systems are rich in nonlinear dynamics. Engineers who work in this field are frequent chaos observers whether they admit (or know) it or not. Because engineers are interested in the usual regular periodic operating regimes, they tend to either ignore the “strange” behaviour that they encounter in their workbench or simply derive some quick fixes via some trial-and-error procedures.
 In this talk, a brief overview of some aspects of bifurcation and chaotic behaviour of power electronics circuits is given, with emphasis on the typical bifurcation scenarios arising from the smooth and nonsmooth characteristics of power electronics circuits. The dc/dc converter will be used as the main illustrative example. It will be shown that power electronics circuits exhibit many standard bifurcations such as Hopf, period-doubling and saddle-node, as well as a special type of bifurcation known as border collision. These types of bifurcations may occur in power systems and wind power generator systems.
