  1. 1. Improvement of a load circuitfor power consumption within ananogrid application

    University essay from Uppsala universitet/Elektricitetslära

    Author : Hampus Hahne; [2020]
    Keywords : nanogrid; IGBT; MPPT; analogue technology;

    Abstract : The transistion from fossile fuels to renewable energy goes in a rapidpace. A way to contribute to this process is the nanogrid applicationwith renewable energy sources. A prototyp of this application islocated on the roof of house 8 at Ångström laboratory. The ambition isto connect a wind power source to a battery bank via a MPPT device. READ MORE

  2. 2. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES

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

    Author : Marco Giuliato; [2019]
    Keywords : ;

    Abstract : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

  3. 3. 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

  4. 4. Maximum Inverter AC Current Prediction Based on Junction Temperature Calculation

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

    Author : Shuyu Ou; [2019]
    Keywords : IGBT; Inverter; Junction temperature; Current Limiter; IGBT; Växelriktare; Övergångstemperatur; Strömbegränsare;

    Abstract : Semiconductor devices are widely used in the automotive industry, and they are key components of the inverter and the converter in an electric vehicle. Thus, the concern of protecting the inverter and the converter from damaging operation has been raised. The junction temperature is one of the main considerations. READ MORE

  5. 5. 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.
