This paper presents a methodology, based on 3D electro-thermal simulation, to investigate failures of vertical power MOSFET due to metallization aging of source terminal. The numerical results were correlated with experiment based on past study.
Reliability is a major economic and technical challenge for power electronics. This paper aims at exploring the impact of reconstruction of source metallization  due to ageing on temperature and mechanical strain distributions within a smart power device. Based on 3D FEM electro-thermal simulations, we explore thermal and mechanical impact of source… (More)
This paper describes the automatic generation of a structured-dominant mesh based on an automatic block decomposition obtained using the medial object. The mesh generator will produce a mesh for an arbitrary two-dimensional geometry, where quadrilateral-dominant or triangular meshing is used when structured meshing fails. The domain is automatically… (More)
This paper discusses the implementation of a distributed geometry for parallel mesh generation, involving dynamic load-balancing and hence dynamic re-partitioning of the geometry. A novel approach is described for improving the efficiency of the distributed geometry interface when dealing with irregular shaped mesh partitions.
