The upgrade of the LHC experiments at CERN brings new challenges in the design and integration of the detectors. Among them and to achieve the required channel density, the power distribution to the front-end electronics of the trackers has to be implemented in a more efficient and compact manner. This paper proposes a new powering scheme for the trackers based on the use of custom on-board DC-DC converters. The converters are designed to tolerate high levels of radiation and intense magnetic fields present in the experiments.

Conducted EMI Yield by Static Converters Applied to Power Factor CorrectionThis paper investigates the conducted electromagnetic interference (EMI) yielded by power converters used power factor correction.The topologies discussed in this paper are the boost, interleaved boost and dual boost converters. An analysis of the conducted noise behavior of differential mode and common mode in the converters are presented. All converters are designed in a way that the total harmonic distortion of the input current are same, in order to use the same input filter. It is presented the EMI filter design in order to adapt the converters as the standard of electromagnetic interference, CISPR. Experimental results of converters operating in power factor correction for a load of 300W is presented, as well as, experimental results of EMI analyzing the impact of the use of EMI filter, the alteration of the gate resistance of the semiconductor switches and changed in the configuration of the inductor boost for dual boost topology. RESUMOEste trabalho investiga a interferência eletromagnética (EMI) conduzida gerada por conversores estáticos aplicados a correção do fator de potência. As topologias discutidas neste artigo são os conversores boost, boost intercalado e dual boost. Uma análise do comportamento dos ruídos conduzidos de modo diferencial e de modo comum nos conversores são apresentados. Os conversores são projetados de forma que a taxa de distorção harmônica da corrente de entrada seja a mesma, com o objetivo de usar o mesmo filtro de EMI de entrada. É apresentado o projeto do filtro de EMI com o objetivo de adequar os conversores a norma de interferencia eletromagnética (CISPR 22). Resultados experimentais dos conversores operando na correçao do fator de potência para uma carga de 300W são apresentados, bem como, resultados experimentais de EMI analisando-se o impacto da utilização do filtro de EMI, da alteração da resistência de gate das chaves semicondutoras e alteração da configuração do indutor boost na topologia dual boost.

“…Therefore the redirection of field lines is limited we observe a calculation mistake for practical setups in the range of 15%, which is acceptable for EMI simulation. The work flow for interference prediction starts with a circuit simulation of the device including the active and passive components, parasitic properties like equivalent series inductance (ESL) of capacitors or inductances of lines [5]. The function of the circuit is simulated either in time or frequency domain.…”

“…Additionally, coupling effects between the passive components gather influence when placed close to each other, as mentioned in a recent research paper [1]. Some effort was made to find out more about the coupling effects and how to calculate them [2][3][4][5].…”
