The Modelica.Electrical.QuasiStatic library addresses the analysis of electrical circuits with purely sinusoidal voltages and currents. The main characteristics of the library are:
omega of the voltages and currents of
a circuit are determined from a reference angle gamma by means of
omega = der(gamma).gamma is not a global quantity
since it propagated through the connector.
Therefore, independent circuits of different frequencies can be modeled in one model.The main intention of this library is the modeling of quasi-static behavior of single-phase and polyphase AC circuits with fixed and variable frequency. Quasi-static theory and applications can be found in [Dorf1993], [Burton1994], [Landolt1936], [Philippow1967], [Weyh1967], [Vaske1973].
A general electrical circuit can be a DC circuit, an AC circuit with periodic sinusoidal or non-sinusoidal voltages and currents or a transient circuit without particular waveform of voltages and currents. Therefore a coupling model between a quasi-static circuit and a general (transient) electrical circuit has to be designed carefully taking the specific application into account. As an example, you may look at the ideal AC DC converter, which is used in the rectifier example.
