抄録
<p>In recent years, faster switching speeds have made it possible to reduce the size and increase the efficiency of power electronics devices. On the other hand, higher switching speeds have led to an increase in electromagnetic noise (EMI) generated by the devices. To prevent prolonged development time due to this EMI, front-loading development utilizing simulation is effective, and various EMI analysis methods have been proposed. In particular, a method for modeling the entire device with a three-dimensional electromagnetic field simulation using FEM is beneficial in verifying and improving the layout design before prototyping. In this method, modeling of magnetic components, one of the important components in power electronics, becomes a challenge. In this paper, we propose a modeling method for magnetic components to predict EMI by 3D electromagnetic field simulation for high frequency applications. With the proposed method, the measured and simulated impedance characteristics of a choke coil used in a boost chopper in industrial equipment in the frequency range from 150 kHz to 30 MHz agree with each other within an error of less than 15%.</p>
