1. 1. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Henrik Johansson; [2022]
   Nyckelord :Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

   Sammanfattning : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. LÄS MER

3. 2. Mätsystem för effektförluster i en högfrekvenstransformator

   M1-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

   Författare :Tina Strömberg; José Gumucio; [2012]
   Nyckelord :Transformer; Power-loss; half-bridge; dimensioning; Transformator; förluster; halvbrygga; dimensionering;

   Sammanfattning : To measure losses in a transformer with today’s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. LÄS MER
