  3. 2. Bi-directional Charging System Design for a set of Li-ion Batteries Located at Angstrom Laboratory Campus of Uppsala University

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Mosab Mohammed; [2023]
    Nyckelord :Onboard chargers; bidirectional charging system;

    Sammanfattning : In this study, onboard chargers for EVs are investigated and a design of bi-directional onboard chargers is proposed and simulated. The goal of the charger is to be built in the future to be used in the test setup at Uppsala University. LÄS MER

  4. 3. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joseph Asanbe; [2022]
    Nyckelord :late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Sammanfattning : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. LÄS MER

  5. 4. Design of an electric motor (PMSM) & manufacturing lab

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Lama Awawda; [2021]
    Nyckelord :Permanent magnet synchronous machine; PMSM; Finite element analysis FEA ; FEMM; Hairpin winding; Motor assembly; Prototype;

    Sammanfattning : The thesis presents deals with the design, analysis, test and control of permanent magnetsynchronous motor(PMSM). An analytical model was carried out based on the d-q frame and the equivalent circuit of PMSM, theanalytical model gives an approximation value of the machine parameters and is carried out byequations from the listed references.
