pi2t

Pi to T transformation

Calling Sequence

Zabc = pi2t(Z123)

Parameters

Zabc

impedances of T network = [Za,Zb,Zc]

Z123

impedances of Pi network = [Z1,Z2,Z3]

Description

pi2t(Z123) performs Pi to T transformation. Z123 and Zabc are Lx3 matrices, for transforming several cases at once. the transformation equations are:

Za = Z2*Z3/U, Zb = Z3*Z1/U, Zc = Z1*Z2/U, where U = Z1 + Z2 + Z3

Z1 = V/Za, Z2 = V/Zb, Z3 = V/Zc, where V = Za*Zb + Zb*Zc + Zc*Za
