Common-Mode and Differential-Mode Analysis of Common Mode Chokes

Abstract

In this paper three methods for the measuring common-mode and differentia-mode S-parameters of common mode chokes are presented. The three methods involve (1) ABCD chain matrix, 2) using hybrid couplers and 3) modal decomposition. Each measurement method provides a specific level of accuracy. The modal decomposition method can work up to 10 GHz. Given a full characterization of a common mode choke, a passive equivalent circuit model can be synthesized that provides a fundamental understanding of the physical performance. SPICE equivalent circuit model of common mode chokes and the extraction of model parameters are provided.
