Abstract :
We studied a CMC model with a one-turn toroidal core, which is easily used in 3D field simulators. The calculation model of a CMC differs from the actual shape, so we need to correct the CMC´s characteristics. When we calculated the noise-suppressing effect of the CMC, we used relative permeability, which differs from the actual value, to approximate the actual characteristics of a CMC. From the comparison of calculated results with measurement results, the calculated results were comparable to the measurement results. We confirmed the validity of our model.
