Does it mean that when I calculate the complex inductance, the multipilication of imaginary part of inductance and angular freqeuncy should be same resistive loss? At least the simualtions I played with, I could not get any correlation. The imaginary part of inductance is too low. No, the loss that you get by calculating (1/2)*omega*Li*i^2 is just the core loss. This is in addition to the resistive losses in the coils. Dave.
