1. 11. Power cables in battery electric vehicles used in underground mining : Analysis of electromagnetic dynamics in high-power cables and development of application-specific design strategies for reduction of EMI

   University essay from Uppsala universitet/Elektricitetslära

   Author : Chisom Miriam Ekweoba; [2019]
   Keywords : ;

   Abstract : The electrification of the automotive industry is growing in popularity, considering the environmental impacts of the conventional diesel-powered automobile. However, from the electromagnetic compatibility (EMC) viewpoint, it is observed that the use of variable-frequency drives (VFD) and relatively high-power cables to propel electrical motors has led to a considerable rise in electromagnetic interference (EMI) within and outside the machine.

4. 13. Additive weld manufacturing and material properties effect on structural margins

   University essay from KTH/Lättkonstruktioner

   Author : Daniel Arvidsson; [2018]
   Keywords : ;

   Abstract : the FE analyses. Traditionally all parts are modeled with isotropic base material. Analyses are made on a part of the nozzle which includes both a butt weld and metal deposition and which is an interface to another part causing loads that has to be sustained by the weld and the MD.
