パーミアンス-キャパシタンスアナロジに基づく単相コモンモードインダクタの回路シミュレーションモデル

抄録

In this paper, the authors propose a circuit simulation model of a single-phase common-mode inductor based on the permeance-capacitance analogy. In the proposed model, the frequency dependency of complex permeability and the leakage inductance are modeled by using electric circuit components. This electromagnetic circuit is realized using gyrators. Furthermore, an electric component, such as a winding stray capacitance, is modeled separately. In the present study, the proposed model is constructed using LTspice. Comparisons between the measurement and simulation results indicate that the proposed model can analyze common-mode inductor impedances with respect to the differential-mode and the common-mode simultaneously.
