Transient Field-Circuit Coupled Models of Electrical Actuators

For simulating electrical energy transducers, transient 3D finite-elements models are used. Since the behaviour of electrotechnical devices is highly influenced by the driving electrical network, such models have to be extended by circuits. This paper discusses advanced field-circuit coupling techniques, models for the coils appearing in the finite-element model and appropriate solution techniques. Moreover, switching elements such as e.g. diodes and thyristors, are considered.
