Saturable transformer
This block implements an saturable transformer.
The equivalent circuit is shown in the figure below:
The circuit is same than the Single Phase Ideal Two Winding Transformer, except that the magnetizing inductance has been replaced by its saturated version, which model consists of a controlled current source in parallel with an RC snubber. The value of the generated current is determined by the voltage measured across it.
