Equivalent circuit of coupled inductances

There isn't a general "equivalent circuit" that's any simpler than the straightforward mesh with self inductances and mutual coupling coefficients between each winding and all other windings.

I found it easiest to just set up the mesh equations in MathCAD and then solve for whatever dependent variables were of interest. The specific matter of multiple coupled inductances may be treated in a text somewhere, but I never found one.

The equivalent circuit of several mutually coupled inductances is just another simple T network.

Progressively reduce Pi to T, T to Pi, Pi to T, etc.

I read in sci.electronics.design that Reg Edwards wrote (in ) about 'Equivalent circuit of coupled inductances', on Thu, 3 Nov 2005:

When hungry, raise Pi to the T'th.

Only if you're a pi eta. And often alpha pi and a kappa T is enough.

Phi! Can anyone get their ducks in a rho and come up with a nu and beta pun, even a real kappa? Will we run the whole gamma of Greek alphabet whimsies?

Psi! Iota be able to do better than that!

Pie are round. Cake are square!
