A systematic method for constructing models in the complementarity framework from a bond graph is proposed. Bond graphs with and without storage elements in derivative causality are considered. The proposed method allows the study of switching systems represented by a bond graph model of fixed causality. The proposed methodology allows the complementarity framework to be exploited in different engineering areas by using bond graphs. The idea of representing a unidirectional switch with a model that is essentially the same as a diode is presented. By employing a similar representation for diodes and switches, the modeling and simulation of power switching converters are simplified and become more intuitive. Two application examples are shown. A non-inverting buck-boost converter and a zeta converter with an element in derivative causality are simulated.

“…8 In the two-port category, the simplest structure is the MTFs modulated with gain taking values over the set {0, 1}; 9 the s witchable bonds’ formalism presented in Broenink and Wijbrans 10 as conditionally present bonds; this approach has some problems, caused by the fact that the boundary conditions on the adjacency of the switchable bonds are not always explicitly defined in all the switching modes. 11 Recently, in Nacusse and Junco, 12 a switchable structured bond, called SS-bond, has been presented as an extension of the switchable bonds correcting the shortcoming of the latter and representing all the possible commutation modes between two power ports. Also, in Nacusse and Junco, 12 the single-port switched structure ideal switch has been represented using SS-bond, showing the connivance of the single-port and two-port switched structures.…”

This article presents two dual-controlled switched bond graph structures called generalized switched junction structures. These structures can represent all the interconnections enforced by commutations involving bond graph elements around standard 0- and 1-junctions. Moreover, pre-existing multiport switched bond graph formalisms like controlled junctions and switched power junctions can be represented as particular configurations of generalized switched junction structures. The generalized switched junction structures incorporate some algebraic constraints into their equation sets, which in the bond graph domain can be represented with residual sinks, in order to make them able to keep fixed the causality assignment even under ideal switching (zero transition time switching), as a convenient tool for simulation purposes. However, just performing some minor modifications on their internal implementation using basic bond graph components, the generalized switched junction structure can also be used to model commutations relaxing the ideal switching hypothesis in favor of the approximate one which introduces some parasitic components, which is frequently used as a means to avoid possibly appearing causality changes. The generalized switched junction structure can be implemented in a compact way at high level using the equation sets defining their behavior, or in detailed way using elements out of the standard set of bond graph components.
