  1. 1. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Anton Grönberg; [2024]
    Nyckelord :Real-Time simulation; Power System Simulation; OPAL; DER;

    Sammanfattning : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

  3. 2. State of Health measuring of NiMH batteries using simple electronic components.

    Kandidat-uppsats, Linköpings universitet/Fordonssystem

    Författare :Linus Classon; [2024]
    Nyckelord :SoH; NiMH; State of Health; Batteries;

    Sammanfattning : The possibility of measuring the state of health of a NiMH battery without doing it in a lab is evaluated, the goal was to see if it was possible to perceive any differences between batteries of different states of health and whether it’s worth further exploring this solution in a more detailed manner. In order to try and extract and analyze the state of health of the batteries a series of tests consisting of discharging batteries at different lengths of times and different resistive loads were made, the voltage of the batteries being captured by a multimeter.

  4. 3. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress

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

    Författare :Agnimitra Saha; [2023]
    Nyckelord :Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

    Sammanfattning : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. LÄS MER

  5. 4. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  7. 5. Förbättring av nätstruktur i området Forshälla.

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Anton Dafgård; Hugo Junhav Land; [2023]
    Nyckelord :Nätstrukturer; kvalitetsarbete; Uddevalla kommun;

    Sammanfattning : När mycket nybyggnation uppstår i ett område behöver nätstrukturen analyseras för att säkerställa att den befintlig strukturen klarar av det nya effektbehovet. I Forshälla byggs sommarstugor om till permanentboende, nya bostadsområden byggs längst med kusten och hushåll monterar solceller och elbilsladdare på deras hus. LÄS MER
