    • Influence of fast rise voltage and pressure on partial discharges in liquid embedded power electronics 

      Abdelmalik, Abdelghaffar Amoka; Nysveen, Arne; Lundgaard, Lars Esben (Peer reviewed; Journal article, 2015)
      Initiation of partial discharges at the highly stressed regions of an Insulated Gate Bipolar Transistor (IGBT) can lead to degradation of the insulation and eventual total breakdown of the system. In this work, an experimental ...

    • Partial Discharges in Narrow Gaps on Power Electronic Converter 

      Abdelmalik, Abdelghaffar Amoka; Nysveen, Arne; Lundgaard, Lars Esben (Chapter, 2014)
      The quest for power electronic converters to operate in a subsea pressurized environment that is completely filled with appropriate dielectric liquid brings about the need to study the insulation performance of liquid in ...
