  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  3. 2. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Arvin Razavi; [2023]
    Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER

  4. 3. 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

  5. 4. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

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

    Författare :Martin Fajerberg; Mattias Nylander; [2022]
    Nyckelord :Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Sammanfattning : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. LÄS MER

  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
