1. 1. Development of a cable analysis theory based on integral equation derivation

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Sandra Larsson; [2023]
   Keywords : ;

   Abstract : Electrification of transportation is a major subject of research today, especially in air travel. The increasing number of electronics and cables also increases the interference between them. From this, interest grew to increase the accuracy of electromagnetic modeling of cables. READ MORE

3. 2. Superconducting gates for InP HEMTs

   University essay from KTH/Tillämpad fysik

   Author : Sebastian Alveteg; [2023]
   Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

   Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

4. 3. Stray capacitance study for HVDC Classic : The use of PSCAD and Mathcad to calculate the equivalent stray capacitance

   University essay from Uppsala universitet/Elektricitetslära

   Author : Saga Dalersand; Fredrik Gjöthlén; [2023]
   Keywords : ;

   Abstract : The reactors placed in the thyristor valve designed by Hitachi Energy have reactor losses which are dependent on the stray capacitance. To find out the stray capacitance, and further get to know the reactor losses, a PSCAD simulation is performed. READ MORE
