The built-in AC line chokes have an inductance of L=94µH.
According to the formula: Zf = Rf +JXf
We can estimate the Rf with the power loss.
Maximum losses are given at 640W.
By using P=R*I², we obtain for one phase:
By using the impedance formula Xf = 2*π*f*Lf, we obtain:
Regarding the value, Rf is negligible compare to Xf.
We can consider the impedance Z = Xf = 29.53mΩ.
