A new interleaved multi-channel DC/DC converter specially dedicated to low voltage, high current applications

Alfred Rufer, Philippe Barrade, Blaise Destraz

Making transportation systems more energy efficient is one of the key challenge in this century. This paper presents a solution for increasing the efficiency of an electrical scooter by adding a supercapacitive energy storage in parallel to the original ba ...

Analytical expression for electric filed between two facing strip electrodes in microchannels

Philippe Renaud, Olof Pontus Linderholm, Urban Seger

An analytical solution is presented for the electric field between two facing strip electrodes situated in a microchannel, as frequently used in impedance cytometry applications. The measured change in resistance as induced by a 5 mm bead moving through th ...

PLC studies in China as a contribution to the development of international standards

Michel Ianoz

In the field of PLC, the standardization process on international level is progressing very slowly. The EMC Laboratory of the North China Electric Power University has received the task to develop a measurement method for the field radiated by PLC installa ...

A new solution for increasing the efficiency of an electric scooter with supercapacitors through a novel, interleaved multi-channel DC/DC converter

Alfred Rufer, Philippe Barrade, Blaise Destraz

Scooters are a well-established transport system for short distances – particularly within cities. Currently, the majority of scooters are petrol powered. Their engines typically exhibit bad efficiencies and thus contribute to global warming by CO2 product ...

On the estimation of lightning peak currents from measured fields using lightning location systems

Marcos Rubinstein, José-Luis Bermudez

Although, due to the high variability of key parameters such as the return-stroke speed, it is impossible to determine the lightning current accurately from the remotely measured electric or magnetic field for a given event, we show in this paper that, for ...

Simulation of Transient Phenomena in Francis Turbine Power Plants : Hydroelectric Interaction

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Philippe Allenbach, Alain Sapin, Sonia Kvicinsky

Models of hydraulic components based on impedance method have been implemented in a software called “SIMSEN”. This tool allows the simultaneous solution of the electrical, hydraulic, mechanic and control equations ensuring a proper interaction between the ...

Contribution à l'optimisation des entraînements électriques

Cédric Paroz

The choice of the drive composition is an obligatory stage in designing a product including electric drives. The large variety of the elements composing the electric drive (electronics, driving and kinematic chain) leads to a quasi-unlimited number of poss ...

Electromagnetic field interaction with vehicle cable harness: an experimental analysis

Davide Pavanello, Abraham Rubinstein

The paper presents experimental results obtained as part of the GEMCAR European project using the VERIFY EMP simulator belonging to the Swiss Defense Procurement Agency (Spiez). VERIFY generates a vertically polarized electric field with a rise time of 0.9 ...

Electric and magnetic interaction of dyonic D-branes and odd spin structure

Claudio Scrucca

We present a general description of electromagnetic RR interactions between pairs of magnetically dual D-branes, focusing on the interaction of a magnetically charged brane with an electrically charged one. In the boundary state formalism, it turns out tha ...
