  2. 2. Investigation of Trench Gate IGBTs in MMC based VSC for HVDC

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

    Författare :Kruphalan Tamil Selva; [2018]
    Nyckelord :Trench-IGBT; VSC; HVDC; IGBT Driving Methods; Trench-IGBT; VSC; HVDC; IGBT drivningsmekanismer;

    Sammanfattning : The following is a thesis project involving investigation of applicability of trench type IGBTs in present and future VSC based HVDC convertors. The work involves three major sections – theoretical loss evaluation of adoption of Trench technology (both IGBT and BIGT) for HVDC Light® applications, testing the Trench IGBT prototype with existing gate units and finalizing with a hypothesis and a practical solution for unexplained turn-on phenomenon observed during testing.
