Abstract
All power electronic circuits with state feedback controlled switching can be described as nonlinear time-varying dynamical systems, and the occurrence of chaos-where the ripples become aperiodic-is common in such systems. It is shown here that this natural phenomenon can be effectively used in minimising EMI problems in power electronic circuits, because controllers based on chaos spreads the spectrum of power converters, thereby reducing the interference power at any target frequency.
