Electronics

Comparison of stress distributions and failure modes during thermal cycling and power cycling on high power IGBT modules

The paper presents experimental investigations on both power and thermal cycling conditions on 600V-200A six-pack IGBT power modules. Both types of cycles are compared in term of thermomechanical stresses by using Finite Element simulations. Finally…

Degradation behavior of 600 V-200 A IGBT modules under power cycling and high temperature environment conditions

One challenge for automotive hybrid traction application is the use of high power IGBT modules that can withstand high ambient temperatures, from 90 °C to 120 °C, for reliability purpose. The paper presents ageing tests of 600 V-200 A IGBT modules…

An Unsupervised Approach for Subpixelic Land-Cover Change Detection

In this paper, we present a new method for subpixelic land-cover change detection using coarse resolution time series, as they offer a high time-repetitiveness of acquisition. Changes are detected by analyzing the coherence between a coarse…

Les actionneurs électromagnétiques : quels choix pour la robotique ?

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, industrielles ou en…
