MEDICIÓN Y REDUCCIÓN DE LA EMI CONDUCIDA EN CONVERTIDORES DC-DC CONMUTADOS PARA LA DISTRIBUCIÓN DE PODER DE BAJO VOLTAJE EN EL SLHC

Abstract

The upgrade of the Large Hadron Collider (LHC) experiments at CERN sets new challenges for the powering of the detectors. One of the powering schemes under study is based on buck converters mounted on the front-end modules. The switching noise emitted by these converters is susceptible to affect the performance of the powered systems. A model to identify and to control the noise sources of the converter was developed. A reference test setup with associated measurement methods is used to characterize the noise properties of the converter. Complementary tools and simulations were also used to evaluate the noise couplings at system level
