Using the EM simulation tools to predict the Conducted Emissions level of a DC/DC boost converter: Introducing EBEM-CE model

Abstract

DC/DC Boost Converters are commonly used in the electronics industry to provide a raised voltage to a specific function. These converters are constituted by a basic commutation cell (Inductor-MOS transistor-diode-capacitor) managed by an integrated circuit realizing voltage and current control typically running between 100 and 500 kHz. This control's frequency creates high conducted Electromagnetic noise which could cause troubles on the supply network. We propose to use a SPICE modeling to estimate the conducted noise on supply network during CISPR 25 CE measurements. Then, we will intend to build an EBEM-CE model of the converter from these measurements.
