Behavioral circuit modeling of single- and three-phase chokes with multi-resonances

In this paper, a novel multi resonance SPICE-compatible behavioral model and corresponding parameter extraction procedure for single- and three-phase chokes are presented. The model takes into account common-mode and differential-mode behavior of the choke and can be applied to modeling both common-mode chokes and coupled DC chokes. The model parameters are obtained from a straightforward parameter extraction procedure based on measurements. Using this procedure, reliable models in the EMI conducted emission frequency range have been obtained.
