A Bond Graph Approach for the Modeling and Simulation of a Buck Converter

Abstract

This paper deals with the modeling of bond graph buck converter systems. The bond graph formalism, which represents a heterogeneous formalism for physical modeling, is used to design a sub-model of a power MOSFET and PiN diode switchers. These bond graph models are based on the device's electrical elements. The application of these models to a bond graph buck converter permit us to obtain an invariant causal structure when the switch devices change state. This paper shows the usefulness of the bond graph device's modeling to simulate an implicit bond graph buck converter.

Development and investigation of methods of graphic-functional modeling of distributed systems

“…if if or 0 (10) In the case of a non-directed graph, there is no need to use both of the vectors d u i i ⊂ , and to establish the subordination between the parameters θ ij and θ ji by the formulas (9) or (10). In this case, it is sufficient to indicate the number of non…”

“…A similar approach, but in relation to electronic circuits, is proposed in the work [9]. The graphic models implemented in it based on the fuzzy character reproduce and change the connections between the elements depending on the current state of the electronic keys (transistors).…”

“…Either way, it is necessary to generalize the methods, models and means of graph-analytical modeling of distributed technological systems and objects, set forth in the writings [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. In the aspect of the application of these categories in order to research the work and automated design of information management systems, one can distinguish such general limitations and disadvantages:…”

“…This follows directly from the properties of the adjacency of the graph elements provided that the edges are oriented between the corresponding vertices. By providing the substantial redundancy to the corresponding matrices, combining the formulas (9) and (10) in various ways, one can bring them to a symmetrical form. In this case, the anatomical properties in the two parts of the matrix will be duplicated.…”

Steady State Response of Linear Time Invariant Systems Modeledby Multibond Graphs

“…A versatile approach to the synthesis and design of a bond graph model and a Kalman filter observer for an industrial back-support exoskeleton was presented in [6]. The modeling of bond graph buck converter systems was analyzed in [7]. Bond graph modeling and the kinematic and dynamic characteristics of a piezoelectric-actuated micro-/nano-compliant platform system were investigated in [8].…”
