Abstract

This paper presents a new frequency-domain method for predicting conducted electromagnetic interference (EMI) noise in phase-leg-based power converters. Based on modular-terminal-behavioral (MTB) equivalent EMI source model for a switch module (half of a phase-leg) developed at a given operating condition, the proposed approach applies the MTB model to predict EMI noise for the converter consisting of multiple phase-legs. Use of the methodology for both differential-mode (DM) and common-mode (CM) EMI noise prediction is investigated. Verification was carried out through experiments using a full-bridge (FB) converter as an example. This modular modeling approach can be applied to other types of phase-leg-based converters
