Title:
Structural Analysis of Coupled Electromagnetic Fields and Electric Circuits.
Abstract:
The coupled simulation of spatially distributed device models and lumped electrical circuits has a long tradition in mathematics and engineering, particularly in the modeling of semiconductors and energy converters such as electrical machines. This talk presents a mathematical analysis of electromagnetic field–circuit coupling in energy-conversion systems. Special attention is given to the differential-algebraic structure of the governing equations and its implications for the coupled problem. In particular, we examine the (differentiation) index of the resulting systems and discuss energy conservation and related structural properties from a port-Hamiltonian-like perspective. Finally, the example of a foil conductor model illustrates how such structural analysis can significantly increase numerical stability by minor modifications of the underlying discretization scheme.
