  1. 1. Design and construction of a voltage source converter for a laboratory setup

    University essay from Uppsala universitet/Elektricitetslära

    Author : Lindblom Henrik; [2019]
    Keywords : Voltage Source Converter; IGBT; HVDC; FPGA;

    Abstract : The grid stability and reliability is facing new challenges as the emerging number of intermittent renewable sources connected to the grid is increasing. With the introduction of the insulated-gate bipolar transistor, the three-phase VSC has grown more popular and is used in many applications. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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.

  3. 3. Technical Feasibility Study of an IGBT-based Excitation System

    University essay from Uppsala universitet/Elektricitetslära

    Author : Johan Frisk; [2017]
    Keywords : Cabinet design; inverter cabinet; IGBT; excitation system; EMC; electrical connection; Skåpdesign; IGBT; magnetiseringssystem; EMC; elektrisk anslutning;

    Abstract : This thesis aims to design a cabinet to house some of the required hardware to realize a 1000 A IGBT inverter controlled static excitation system. In the thesis practical design considerations are identified and solved. The suggested excitation system requires a cabinet to house the inverters. READ MORE

  4. 4. Reliability Study of SiC-Based Power Electronic Devices in DC-DC Converter Used in Heavy-Duty Electric and Hybrid Vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sanaz Namayantavana; [2017]
    Keywords : ;

    Abstract : A DC-DC converter is used in electrified and hybrid vehicles to supply powerto the low voltage (ex. 24V) system including headlights, horn, air conditioningsystem, wipers, radio, etc. The converter is fed from a high voltage (ex. 650V)battery, which is available in electric/hybrid vehicles, and transfers a relativelyhigh power.

  5. 5. Development of EMT Simulation Model to Use RMS Control Model

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Priya Kalikavunkal; [2016]
    Keywords : ;

    Abstract : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. READ MORE
