  1. 1. Investigation of current sensing techniques for a high bandwidth application : Focusing on Hall-Current Sensing

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

    Författare :Enric Ametller; [2023]
    Nyckelord :Current sensing; High bandwidth; Inverter; Hall-sensors; Strömavkänning; Hög bandbredd; Inverter; Hall-sensorer;

    Sammanfattning : With the ongoing surge in electrification within the automotive industry, the demand for high-power inverters is steadily on the rise. Furthermore, these inverters are now expected to handle increased power loads while maintaining enhanced efficiency. LÄS MER

  3. 2. Konstruktion av extern linjärgivare för kranutskjut : Utveckling och utvärdering av sensorteknik för att förbättra positionsangivning för kranutskjut

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Dekran Zakar; Tobias Burström; [2023]
    Nyckelord :Design; extern linjärgivare; kranutskjut; produktutveckling; sensor; vinkelgivare;

    Sammanfattning : In this work, a study, design and development process for an external linear sensor for one of Cranabs forestry machines has been carried out. The purpose of the degree project was to investigate and develop various design proposals for alternatives to linear sensors in crane extensions that are not built into a hydraulic cylinder. LÄS MER

  4. 3. Short-circuit current detection in electric vehicles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Max Torbjörner; [2022]
    Nyckelord :Electric vehicles; Current measurement; Short-circuit; BEV Trucks; BJB;

    Sammanfattning : In recent years the vehicle industries have been making much efforts to reduce the environmentalimpact by switching from the traditional combustion engine to electrification with battery driven electricvehicles. Producing electric trucks requires more batteries and operates at a higher voltage and currentthan commercial electric cars. LÄS MER

  5. 4. Occupancy detection and prediction with sensors and online machine learning : Case study of the Elmia exhibition building in Jönköping

    Master-uppsats, KTH/Byggvetenskap

    Författare :Allen Chen; [2022]
    Nyckelord :;

    Sammanfattning : Buildings account for approximately 40% of energy consumption in the EU, and despite drastic increasing measures for energy efficient operation, the net value of energy consumption is expected to continue increasing because ofincreasing urbanization.While there has been increasing work done on managing external loads such as adapting to unpredictable climates, the research on internal loading, such as occupants, is still nascent.

  7. 5. Shielding of Transformer Stray Fields in Trains

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

    Författare :Lárusdóttir Lára Ólafia; [2022]
    Nyckelord :;

    Sammanfattning : Generally, a transformer will produce stray magnetic fields. Aboard trains, the transformer’s stray fields can pose problems to other components inside or outside the train. Further, regulations require the magnetic field to be below certain levels in the passenger area. LÄS MER
