Transformers Modeling

The modeling methodologies of two or multiple winding transformers and their uses are mentioned several for the purpose of disseminating what has been done in the area.

When studying electrical systems, it is necessary to elaborate models that simulate their behavior. The purpose of the modeling is to create a tool that allows studying the behavior of the electrical system, for example, a transformer, when the system itself is inserted in an electric circuit.         Boston Gear 5M319090

The modeling does not supply the experimental analysis, but instead, the results of the modeling of an electrical system must be complemented, thus concluding the study of the electrical system in question.

Models that include the saturation and losses of the nucleus, namely the hysteresis cliclo, have as equivalent circuit a coil in parallel with a resistance, where the magnetic behavior and its characteristics are represented only in a single electric circuit.

From the implementation point of view, the use of discrete transformer circuit models, which are related to a non-linear inductor in parallel with a non-linear resistance, prove to be complex, because the resulting equivalent circuit for the transformer and the matrices of impedance is complex and the matrices are constituted by a large number of elements.
