This letter presents a novel integration approach for the electromagnetic interference choke. A low-permeability differential-mode (DM) choke is placed within the open window of the common-mode (CM) choke. Both chokes share the same winding structure. With the proposed approach, the footprint of inductors is greatly reduced, and high-DM inductance can be achieved. First, small-signal measurement is...
This paper presents various strategies in a systematic way to reduce both differential mode (DM) and common mode (CM) noise using passive filter in a dc-fed motor drive. The type of grounding and components used is the key to a good design in order to optimize filter size and performance. Grounding schemes, materials comparison (ferrite vs. nanocrystalline core) and a new integrated filter structure...
Integrated transmission-line filters were previously proposed to attenuate conducted electromagnetic interference (EMI) produced by high-frequency switching power converters. This paper investigates how a filter, fabricated using planar processing technologies, and power converters are modeled to accurately predict the EMI characteristics of the system. Experimental results are provided for the first...
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...
