Machining of various electrically non-conductive materials is possible with Spark Assisted Chemical Engraving (SACE). Even though this technology presents several interesting properties like simplicity, flexibility and the possibility to obtain very smooth ...
With the work reported in this manuscript we have essentially contributed to the electrical characterization and modelling of high voltage MOSFETs, more particularly DMOS architectures such as X-DMOS and L-DMOS able to sustain voltages ranging from 30V to ...
We present local and non-local electron transport measurements on individual multi-wall nanotubes for bias voltages between 0 and about 4 V. Local current–voltage characteristics are quite linear. In contrast, non-local measurements are highly nonlinear; t ...
An in situ methodology is proposed to characterize the impedance mismatch at each power line communication transmission port in medium voltage network. Based on path loss and impedance measurements, a complete characterization of a non energized medium vol ...
In the first part of this paper, the status of the 140-GHz continuously operated gyrotrons with an output power of I MW for the stellarator Wendelstein 7-X will be described. With the first series tube, an output power of 1000 kW has been achieved in short ...
The reactive liquid infiltration (RLI) technique, applied to-the MgB2 material, has allowed us to obtain either bulk or wire samples of good transport properties. The evaluation of the voltage-current characteristics, V-I-n, for typical samples, measured b ...
The steady-state electrical behavior of cation-selective ionophore membranes with different kinds of ionic additives was studied on a theoretical basis. Membranes with both mobile and fixed anionic sites exhibit nonlinear current-voltage curves, which is i ...
In the framework of the conductor optimisation task (CONDOPT) five NbTi subsize cable-in-conduit conductors with parametric variations were fabricated. The DC performance of these conductors tested in the SULTAN test facility [IEEE Trans. Appl. Supercond. ...
This work reports on the analysis of high voltage lateral devices. Two different architectures, self-aligned LDMOS and non-self-aligned XDMOS are presented and used in this work. For the separation of the physical effects that take place inside the HV devi ...
Simulation results relevant to realistic configurations of medium-voltage (MV) and low-voltage (LV) distribution systems provide useful information to evaluate both the expected level of power quality problems on LV networks due to lightning and the benefi ...
