Frequency-domain modeling of integrated electromagnetic power passives by a generalized two-conductor transmission structure

This work treats the modeling of integrated electromagnetic power passives for integrated power electronics modules by using a distributed conductive structure approach. The distributed L-C cell is chosen as the basis for modeling. This work presents the modeling of an L-C cell through the proposed generalized transmission structure theory that can be applied to both balanced and unbalanced current distributions. The load characteristics of a generalized transmission structure are investigated. The proposed theory has been extended to cascaded structures as well. The calculation results correlate well with the impedance measurement results. Some practical design issues are also discussed.
