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

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.
