1. Development of a cable analysis theory based on integral equation derivation
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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. LÄS MER
2. Superconducting gates for InP HEMTs
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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. LÄS MER
3. Stray capacitance study for HVDC Classic : The use of PSCAD and Mathcad to calculate the equivalent stray capacitance
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : 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. LÄS MER
4. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps. LÄS MER
