The SimpleTransformer is a two-port component 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
v1 = jω*(L1*i1+ M*i2),
v2 = jω*( M*i1+L2*i2),
where M²<L1*L2 is assumed.
The parameters L1 and L2 denote the primary and secondary self inductances, respectively,
while M is called mutual (or coupling) inductance.
All inductances have constant values.
