t2pi

T to Pi transformation

Calling Sequence

Z123 = t2pi(Zabc)

Parameters

Zabc

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

Z123

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

Description

t2pi(Zabc) performs T to Pi transformation. Z123 and Zabc are Lx3 matrices, for transforming several cases at once. the transformation equations are:

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

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