  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. Configurable, scalable single-ended sense amplifier with additional auxiliary blocks for low-power two-port memories in advanced FinFET technologies

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Limitha Subbaiah Kumar Nangaru; [2022]
    Nyckelord :CMOS Complementary Metal Oxide Semiconductors ; DRC Design Rule Check ; Process Corners; FinFET Fin Field Effect Transistor ; IC Integrated Circuit ; LVS Layout Versus Schematic ; Monte Carlo; Nominal Voltage; PDK Process Design Kit ; Power Delay Product; Read Bit Line; Read Word Line; SoC System on Chip ; SRAM Static Random Access Memory ; Threshold Voltage; Technology and Engineering;

    Sammanfattning : System on Chip (SoC) designs contain a variety of Intellectual Property (IP) cores, including digital signal processing blocks, media and graphics processing units, as well as processing core units that employ multiple-port memories to enhance performance and bandwidth. These memories allow parallel read/write operations from the same memory blocks from different ports. LÄS MER

  4. 3. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FAISAL SEDEQI; [2020]
    Nyckelord :;

    Sammanfattning : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. LÄS MER

  5. 4. Ersätta APU:n med SOFC-GT Hybridsystem inom luftfarten

    M1-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Javid Sarwari; Abbas Heidari; [2018]
    Nyckelord :SOFC; SOFC-GT Hybridsystem; Auxiliary Power Unit APU ; Fuel Cells; Aircraft; Aviation.; Bränsleceller; Emissioner; Växthuseffekten; Ersätta APU:n; Klimat; Civila luftfarten; Hybridsystem.;

    Sammanfattning : The current Auxiliary Power Unit (APU) contributes a lot to the greenhouse effect in terms of emissions, and in the form of noise and also is very heavy. The need for more electricity has increased in aircrafts and therefore major aircraft suppliers like Boeing and Airbus want to switch to more electric aircraft (MEA) which is lighter and has less environmental impacts.
