Abstract
This paper proposes a remarkably efficient modeling method of stray magnetic couplings in an Electromagnetic Compatibility (EMC) filter focusing on a dominant magnetic field in a power electronic device. The proposed modeling method is applied to a filter performance simulation of an EMC filter for a Silicon Carbide (SiC) solar inverter and its effectiveness is verified by comparing a measurement result and a simulation result. By using the proposed modeling method, the influence of the stray magnetic couplings on the filter performance can be well predicted and matched with the measurement result and the simulation result using the conventional modeling method. Accordingly, the number of the stray magnetic couplings required for the accurate prediction can be dramatically reduced from 325 to just one.
