Switching-sequence based global stability and control of standalone and interactive power converters

Applications of switching-power-electronics systems (SPES) have grown leaps and bounds over the last several decades encompassing traditional areas such as telecommunication, motor drives, space, aerospace to more recent areas of smart grid, microgrid, electrical vehicles for automotive, naval, and aerospace applications [1]-[3]. Depending on the nature of the applications, the SPES topologies can vary and so can the nature of the loads (e.g. passive, nonlinear, switching, pulsating, dynamic, interactive) [4]. Such wide variations in SPES application domains and operating conditions have brought out the need for a more unified analysis approach and one that can address wide operating conditions rather being focused primarily on conventional small-signal variations and also does predictions without excessive simulations. The latter is especially difficult for nonlinear and interconnected and network problems [5]. In this paper an overview of wide-application results based on a new switching-sequence-based analysis and control approaches [6] have been provided along with an overview of the theory. Additional references of the author have been provided for the reader to review more comprehensive details of the new approaches and mechanisms for control ad stability applications. The results demonstrate the wide applicability of the new approaches and prediction outcomes that go beyond several existing approaches [7]-[10].
