  1. 1. Development of a High Current Charger for Small Electric Boat Commuting

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

    Författare :Axel Back Enoksson; Axel Boström; [2023]
    Nyckelord :;

    Sammanfattning : Electrification of the transport system is an important societal project which we are currentlyundergoing. With improvements in battery technology it is now possible to construct quite powerfulpersonal vehicles to replace combustion engines in not only cars but also motorcycles and boats. LÄS MER

  3. 2. 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

    Sammanfattning : The sustainable future in our already electrified world includes solar power generation, battery storage, and electric vehicles all which requires DC systems. DC breakers play a key role in operation and protection within the DC system. LÄS MER

  5. 4. Dynamics of an ultra-fast Thomson actuated HVDC breaker

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Miguel Álvarez Sánchez; [2017]
    Nyckelord :HVDC; Ultra-fast Circuit Breaker; Thomson coil actuator; HVDC; ultra-snabb strömbrytare; Thomson-spole manöverdon;

    Sammanfattning : High Voltage Direct Current (HVDC) is a rapidly growing form of power transmission that offers advantages with respect to conventional AC networks. One of the key elements that will allow the generalization of the HVDC grids is the Circuit Breaker (CB), which has to interrupt high DC currents in extremely short times. LÄS MER
