Real-Time Computation of Thermal Constraints in Multichip Power Electronic Devices

In this paper, we present an implementation of a thermal modeling method, based on thermal impedances analysis and applied to a multichip module used as a power converter. Analytical functions of thermal impedances are derived from direct…

Characterisation of silicon carbide schottky diodes and COOLMOS transistors at high temperature

The highly doping level of the base region of COOLMOS transistors allows higher temperature operations than with conventional silicon transistors having the same blocking voltage. In this paper, the temperature influence on different SiC Schottky…

Stochastic Maximum Likelihood (SML) parametric estimation of overlapped Doppler echoes

This paper investigates the area of overlapped echo data processing. In such cases, classical methods, such as Fourier-like techniques or pulse pair methods, fail to estimate the first three spectral moments of the echoes because of their lack of…

Versatility of aqueous micellar solutions for self-assembled monolayers engineering

Self-assembly of aliphatic as well as aromatic thiol-terminated molecules was achieved onto a variety of gold surfaces using aqueous micellar solutions. Scanning tunneling microscopy experiments allowed us to demonstrate that the increase in the…

Actionneurs linéaires directs et indirects : performances limites

A partir d'une classification descriptive des actionneurs électromagnétiques et d'un formalisme simplifié de calcul de leurs performances, les auteurs tentent, dans cet article, de dégager et de comparer différentes solutions d'entraînement linéaire…

Modèle CEM d un actionneur électromécanique

La Compatibilité Electromagnétique (CEM) apparaît aujourd'hui comme l'une des contraintes majeures de la conception des structures de l'électronique de puissance et plus précisément sur les variateurs de vitesse. Malheureusement, elle est trop…
