  1. 1. Data Centres as Prosumers: A Techno-Economic Analysis

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jeremy Ericsson Sintong; [2023]
    Keywords : Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Abstract : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. READ MORE

  3. 2. Phase Noise Performance of a PLL Frequency Synthesizer when Powered by Silent Switchers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sampriti Basu; [2023]
    Keywords : Silent Switcher; PLL synthesizer; Phase noise; PCB implementation.; Silent Switcher; PLL-synthesizer; fasbrus; PCB-implementering.;

    Abstract : In use today are ‘normal’ DC-DC switching regulators with considerable switching noise and ringing, which is bad for noise-sensitive applications. This project involves a solution based on ‘Silent Switchers’ to prove its effectiveness in reducing noise. READ MORE

  4. 3. Possibility for Positive Energy Retrofit in Borlänge

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
    Keywords : ;

    Abstract : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. READ MORE

  5. 4. Modelling of electric transients in 24 V power supply systems for commercial vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ajay Ajay; [2023]
    Keywords : ;

    Abstract : Technology is revolutionising every aspect of modern-day transport and evolving rapidly. The traditional electric system of vehicles produced by SCANIA uses a 24 V DC bus system to provide power and ground to all connected electrical units. READ MORE

  6. 5. 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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE
