Bond-graph enumeration of the configurations of power static converters
P. Michel, Bernhard M. Maschke, G. Manesse · 2002
In this paper, we propose bond-graph models and their causal analysis for the systematical enumeration of the possible configurations in the static power converters. This analysis is carried out by considering the switches as ideal (two binary states ON and OFF) and taking into account the commutations constraints. Firstly usual switches are modelled with bond-graph 1-port elements, which state induces the variable topology of the converters networks. The dynamical discrete event behaviour of the converters are described by Petri nets. The states of the Petri nets are defined locally for the ideal switches, and deduced globally for the converters by using a double causal analysis procedure. The method is applied to a voltage bridge inverter structure.>
