IEE Colloquium on '50kV Autotransformer Traction Supply Systems - the French Experience' (Digest No.1993/209)
Why the 2*25 kV alternative? (autotransformer traction supply)
The author describes how it was the electrotechnical aspect in the form of reduction of losses on lines which was attractive in 2*25 kV traction power feeds in France; the first application was in 1981 on the new Paris-Lyon high speed railw...
SNCF relations with the power supplies
EDF, the public utility national grid in France, requires its customers to observe rules so that unacceptable phenomena will not be generated on the high voltage network, the aim being to provide power to its adjacent customers under good c...
The autotransformer and other equipment (for railway power supply)
The author describes the two types of equipment for 2*25 kV railway traction power supply installations: equipment specific to this alternative which is confined to substation transformers (high voltage or very high voltage/2*25 kV) and aut...
Earthing, protection, miscellaneous (of railway power systems)
The considerable increase in recent years of the per unit power of trains as well as their frequency has led the SNCF to take steps to simplify substation traction current return and to limit dangerous parasite voltages which might occur at...
Reliability Analysis of Wireless Power Transfer for Electric Vehicle Charging based on Continuous Markov Process
In this paper, the reliability analysis of wireless power transfer system for charging electric vehicles using Markov process is presented. Since wireless chargers of electric vehicles are supposed to be exposed to various weather condition...
Inverter/converter power density and flexibility improvements through modularity and novel thermal management architecture
This paper explains the technical challenges that come with miniaturization of inverter and converter technology and how Marel addresses these challenges through modularity, specialized manufacturing techniques, and a unique thermal managem...
EMI Shielding Performance of Thin and Thick Graphene Films Placed Within Integrated Power Modules
This paper presents electromagnetic interference (EMI) analysis and the performance of graphene-enhanced shielding. Two types of graphene have practical relevance. The first is synthesized through Chemical Vapor Deposition (CVD) techniques ...
