The VariableSimpleTransformer component is a two-port with variable parameters consisting of two ideal inductors (having no resistance). Between these inductors, there exists a non-ideal coupling. The left port voltage phasor v1, the left port current phasor i1, the right port voltage phasor v2, and the right port current phasor i2 are connected by the following relations:
v1 = jω*(L1*i1+M*i2),
v2 = jω*(M*i1+L2*i2),
where M²<L1*L2 is always assumed. The parameters
L1 and L1 denote the primary and secondary self
inductances, respectively, while M is called mutual (or
coupling) inductance.Attention!!!
To ensure that the phasor domain-based model works in a
quasi-stationary mode, all inductances may alter only very slowly
in comparison with both the nominal frequency f=ω/(2π) and
the dominant time constant of the phasor domain-based model.
Remark:
It is required that M² < L1*L2, otherwise an assertion
is raised.
