Three Winding Mutual Inductance

This block implements a three winding mutual inductance.

The Three-Winding Mutual Inductor block represents a set of three coupled inductors or windings.

The voltage across the three windings is

where:

V_i is voltage across the ith winding.
I_i is current through the ith winding.
L_i is self inductance of the ith winding.
L_m is mutual inductance between windings.

In the preceding equations, currents are positive when flowing into the positive node of their respective inductor terminals.

When you run a simulation that includes this block, the software checks the specified parameter values to ensure that the resulting device is passive. If it is not, the software issues an error.
