Switched junctions in bondgraph for modelling power electronic systems

Abstract

Modelling of switched-mode power electronic systems using bondgraph is difficult because of lack of switch elementing the bond graph. To overcome this problem, we propose the concept of switched junctions. Here, the dominant junctionvariable is switched to emulate the practical switch. A few switched-mode power converters are modelled and simulated to demonstrate the efficacy of using the switched junctions
