This block implements a three-winding ideal transformer (1 primary, 1 secondary, 1 tertiary).
The single-phase three-winding transformer component models three coupled windings on the same core. The magnetization inductance Lm can be linear or with saturation, it is modeled on the primary side of the transformer. Core losses are modeled as RM resistance located on the primary side of the transformer.
