Abstract

Prediction of the common-mode self-capacitance of common-mode inductors is essential to their design in order to ensure effective operation over the frequency range of interest. This paper presents a model for the calculation of common-mode capacitance of a bus-bar-based common-mode inductor. An equivalent circuit of the inductor that accounts for high-frequency effects such as eddy currents in nanocrystalline cores is also set forth. The predicted and measured capacitances are compared for three such inductors.
