A review of applications of nonlinear dynamics in power electronics systems

Abstract

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