Mutual Inductor (mutual_inductor)

The mutual inductor couples two previously specified inductors. There is no limit to the number of inductors that you can couple or to the number of couplings to a particular inductor, but you must specify separate mutual inductor statements for each coupling. Using the dot convention, place a dot on the first terminal of each inductor.

This device is supported within altergroups.

The mutual inductor modifies the constitutive equations of two isolated inductors to

v1 = L11*di1/dt + M*di2/dt

v2 = M*di1/dt + L22*di2/dt

where the mutual inductance, M, is computed from the coupling coefficient, k, using k = |M|/sqrt(L11*L22).

Sample Instance Statement with Two Inductors

l1 (1 0) inductor

l2 (2 0) inductor
