3. 17. Finite element modelling of LV transformer winding to simulate dynamic events occurring under short circuit : In Ansys Mechanical

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Madhu Venkata Sri Prudhvi Bikkina; [2020]
   Keywords : Ansys Mechanical; LV winding; Power Transformer; Short-circuit; Spiraling; Torsional Mode Shapes;

   Abstract : The ability to withstand a short circuit is the most essential feature of a power transformer. The most important reason to design short-circuits proof transformers is to ensure the reliability of the power grid (avoiding black outs etc.) and safety (fire and explosion in case of failure).

4. 18. Radiation effects on wide bandgap semiconductor devices

   University essay from KTH/Tillämpad fysik

   Author : Patric Elf; [2020]
   Keywords : applied physics;

   Abstract : Gallium nitride (GaN) based high-electron-mobility transistors (HEMTs) are used in a wide variety of areas, such as 5G, automotive, aeronautics/astronautics and sensing elds ranging from chemical, mechanical, biological to optical applications. Owing superior material properties, the GaN based HEMTs are especially useful in harsh operation environments e. READ MORE

5. 19. Correlation of numerical simulation methods and failure criteria to experimental burst test

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära
