A review of applications of nonlinear dynamics in power electronics systems

Power electronics circuits are rich in nonlinear dynamics. Their operation ischaracterized by cyclic switching of circuit topologies, which gives rise to a variety of nonlinearbehaviours. Over the past two decades, a lot of research activities have focused on identifyingbifurcations and chaos, and explaining them using the theory of nonlinear dynamics. As powerelectronics engineers gain more knowledge and deeper understanding of nonlinear dynamics inpower electronics, they begin to look for possible applications. As a result, research of applicationsof nonlinear dynamics in power electronics has become a hot topic. Recently, some applications ofnonlinear dynamics in power electronics systems and related theory have been identified. Thispaper tries to provide an overview of these successful applications.
