Recherche & collaboration
Qu’est-ce qui nous rend unique ?
SuperGrid Institute doit son succès aux personnes qui composent nos différents départements de recherche. Nos équipes viennent d’horizons divers, tant industriels qu’universitaires, et la richesse de leur expérience et de leurs compétences rend l’Institut unique.
Chaque personne apporte une expertise spécifique et ce vivier de connaissances offre aux spécialistes de différents domaines la possibilité de collaborer sur des solutions innovantes pour résoudre des problèmes techniques.
L’Institut bénéficie d’étroites relations de collaboration avec des acteurs de l’industrie et des institutions académiques. Alors que les forces complémentaires de nos partenaires apportent des éclairages et des approches innovantes aux défis techniques, nous développons nos départements de recherche en toute indépendance. Des investissements conjoints publics-privés et des projets de collaboration financent le travail.
Les installations de recherche, les plateformes de test et les laboratoires de pointe de SuperGrid Institute sur les sites de Villeurbanne et de Grenoble sont la clé du succès de nos départements de recherche.

Dielectric properties of ceramic substrates and current developments for medium voltage applications
Why are ceramic materials (when compared to organic materials) necessary for the purpose of electric isolation in power modules, especially for medium voltage applications...
Modelling of a 25 kV-50 Hz railway infrastructure for harmonic analysis
This paper presents a methodology for the modelling of a 25 kV-50 Hz railway infrastructure, for frequencies from 0 to 5 kHz. It aims to quantify the amplifications of current and voltage harmonics generated by on-board converters into the infrastructure. A circuit is developed to model the skin effect in the overhead line for time-domain simulations. A new approach, based on state space representation and transfer functions, is also proposed to analyse the interactions between trains.
Design of a 1200 V, 100 kW Power Converter: How Good are the Design and Modelling Tools?
During the design of power converter, design mistakes must be avoided, especially for high voltage and high power converters. Simulation tools can be used to help the designers and limit the risks. This presentation will present a design flow approach used to design and validate a 1.2 kV – 100 kW DC-DC converter which was design from die to converter levels and started for a “blank page”. The presentation is organized in four parts. Firstly, the context of the work is introduced. Then, the simulation flow approach used to validate the design is presented. For this part, the presentation will focus on the system level simulation of one inverter, including the power modules. This part will highlight the main limitations of the current simulation tools found by the designers. In the third part, an enhanced approach is proposed to overcome the limitations and the first results are presented Finally, a conclusion will be presented.
