Etude de l'intérêt de la montée en tension du bus DC pour minimiser les pertes dans l'onduleur d'un véhicule électrique

Currently, autonomy of electric vehicles is one of the most blocking points for developing such mean of transport. An optimization of the efficiency of the power train is thus a primordial objective. The thesis is part of a context of energy…

Experimental investigation of the reliability of Printed Circuit Board (PCB)-embedded power dies with pressed contact made of metal foam

A Printed Circuit Board (PCB)-embedding process using pressed metal foam to connect the top-side pads of power dies is considered. The manufacturing process, simple and highly cost-effective, is described in detail; samples are manufactured and…

Dynamic Magnetostriction of CoFe2O4 and Its Role in Magnetoelectric Composites

Applications of magnetostrictive materials commonly involve the use of the dynamic deformation, i.e., the piezomagnetic effect. Usually, this effect is described by the strain derivative ∂λ=∂H, which is deduced from the quasistatic magnetostrictive…

Robust distributed calibration of radio interferometers with direction dependent distortions

In radio astronomy, accurate calibration is of crucial importance for the new generation of radio inter-ferometers. More specifically, because of the potential presence of outliers which affect the measured data, robustness needs to be ensured. On…

Influence of the temporal resolution of the water consumption profile on photovoltaic water pumping systems modelling and sizing

Photovoltaic water pumping could significantly improve water access, particularly in off-grid rural villages of Sub-Saharan Africa. Earlier, we have developed and validated a numerical model of a photovoltaic water pumping system (PVWPS). Such model…
