  1. 16. An Estimation Method for PV Hosting Capacity of Distribution Grids

    Master-uppsats,

    Författare :Kassem Ezzeddine; [2020]
    Nyckelord :PV; hosting capacity; overvoltage; transformer overload; voltage drop; voltage rise; penetration level; common path;

    Sammanfattning : The Swedish Energy Agency has a target to increase solar photovoltaics (PV) power production by up to 5-10% of the total electricity demand by the year 2040. The PV potential for the residential market is high and its contribution to the total installed PV capacity is expected to increase significantly. LÄS MER

    Sammanfattning : The electrification era has been marked up by an increase in volume of electric vehicles which are directly or indirectly powered by electricity. Railways, roadways and airways are being electrified as we speak at their own respective rate. LÄS MER

  5. 19. SiC MOSFET function in DC-DC converter

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Christian Al Kzair; [2020]
    Nyckelord :SiC; Buck converter; Buck; Silicon carbide; ROHM;

    Sammanfattning : This thesis evaluate the state of art ROHM SCT3080KR silicon carbide mosfet in a synchronous buck converter. The converter was using the ROHM P02SCT3040KR-EVK-001 evaluation board for driving the mosfets in a half bridge configuration. LÄS MER

  7. 20. Comparison between Active and Passive AC-DC Converters For Low Power Electromagnetic Self-Powering Systems : A theoretical and experimental study of low power AC-DC converters

    Kandidat-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Ibrahim Hamed; [2020]
    Nyckelord :Energy-harvesting; electromagnetic; rectifiers; AC DC-converters; Active voltage doublers; Passive voltage doublers.;

    Sammanfattning : Electromagnetic based energy harvesting systems such as Variable reluctance energy harvesting systems (VREH) have shown to be an effective way of extracting the energy of rotating parts. The transducer can provide enough power to run an electronic sensing system, but the problem arises in finding an efficient way of rectifying that power to generate a stable energy supply to run a system, which this report will investigate.
