ITER - Earthing

Damien Fasel, Ugo Siravo, Jonathan Bryan Lister, Philippe Marmillod, Albert Perez, Blaise Marlétaz

Earthing of electrical installations is mainly governed by safety rules. Electromagnetic compatibility also deals with earthing, among other circuit characteristics. Tokamaks are large-scale electrical installations that are known to generate large and low ...

On the Adaptation of Building Controls to the Envelope and the Occupants

David Daum

The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...

Design and fabrication of micro-hotplates made on a polyimide foil: electrothermal simulation and characterization to achieve power consumption in the low mW range

Nico de Rooij, Danick Briand, Michael David Canonica, Jérôme Courbat

The design of ultra-low power micro-hotplates on a polyimide (PI) substrate supported by thermal simulations and characterization is presented. By establishing a method for the thermal simulation of very small scale heating elements, the goal of this study ...

A CLOSED LOOP CONTROL STRATEGY FOR A FREQUENCY-ONLY CONVERTER WITH HIGH EFFICIENCY

Alfred Rufer, Aziza Benaboud

Many electric power generators use gas turbines as power sources, coupled through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine. This paper proposes to replace the mechanical gearbox with a flex ...

Convertisseur de fréquence indirect à rapport de tension fixe

Aziza Benaboud

Many electric power generators use gas turbines as power sources. Typically they are connected to the turbines through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine, which is very often much hig ...

Contribution to the active generator principle for high power electric supply

Massimiliano Visintin

In recent years the use of solid state frequency converters is rapidly increasing in the industrial and power plants where electric machines are installed, since it allows variable speed operations for the electric system, thus becoming a key factor which ...

Inward thermodiffusive particle pinch in electron internal transport barriers in TCV

Olivier Sauter, Stefano Coda, Timothy Goodman, Henri Weisen, Emiliano Fable, Costanza Zucca

Electron internal transport barriers (eITBs) are obtained in TCV with different heating and current drive schemes. They are sustained in steady-state conditions for several energy confinement and current redistribution times. In these scenarios, the densit ...

Supercapacitive Energy Storage for Diesel - Electric Locomotives

Alfred Rufer, Philippe Barrade, Blaise Destraz

Diesel - electric traction is a well established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel powered locomotive is due to the reduced costs compared to the infrastructure cost o ...
