Abstract :
In this paper, a novel extension of the Partial Element Equivalent Circuit (PEEC) method for modeling magnetic components in the frequency domain is presented. The electromagnetic problem is solved by replacing the magnetized object with a fictitious magnetic current distribution in free space. The derived PEEC model is verified on the example of a magnetic toroidal inductor by experimental impedance measurements. Methods of applying the PEEC modeling approach for other magnetic geometries are analyzed.
