  1. 16. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Farhan Akram; [2021]
    Nyckelord :SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Sammanfattning : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. LÄS MER

  3. 17. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application

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

    Författare :Yanick Patrick Frei; [2021]
    Nyckelord :Multiphase machines; Switching patterns; Winding conduction losses; Converter losses; MATLAB SIMULINK; Flerfasmaskiner; Modulatorer; Spolledningsförluster; Omvandlarförluster; MATLAB SIMULINK;

    Sammanfattning : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). LÄS MER

  4. 18. Deep reinforcement learning for real-time power grid topology optimization

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Jacob Rothschild; [2021]
    Nyckelord :Deep reinforcement learning; Dueling Deep Q-Network; electricity transmission network; real-time topology optimization; sustainable energy; Mathematics and Statistics;

    Sammanfattning : In our pursuit of carbon neutrality, drastic changes to generation and consumption of electricity will cause new and complex demands on the power grid and its operators. A cheap, promising, and under-exploited mitigation is real-time power grid topology optimization (RTTO). LÄS MER

    Sammanfattning : Solar Bora AB is a Linköping based company that provides end to end solution for clean and reliable energy. System developed by them generates high power 230V AC to run electrical appliances. LÄS MER

  7. 20. Local energy system - Comparing direct current (LVDC) and alternating current (LVAC)

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Markus Alm; [2020]
    Nyckelord :Local energy system; LVDC; Technology and Engineering;

    Sammanfattning : This thesis uses a case study to compare the viability of using direct current instead of alternating current to supply power to 5 buildings in a local energy system (LES). The case study sought to show how using LVDC instead of LVAC could increase the effectiveness of solar panels (PV), batteries and interconnecting buildings into a local energy system (LES). LÄS MER
