  1. 1. Ray Tracing Algorithm for Dielectric Domes

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

    Author : Maria Pubill; [2023]
    Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

  3. 2. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

  4. 3. Integrating Wind Power into The Electric Grid : Predictive Current Control Implementation

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Ahmad Badran; [2020]
    Keywords : Model predictive control; Wind turbine; Predictive current control; Inverter; Simulink; Active power; Reactive power.;

    Abstract : The increasing penetration of wind power into the power system dominated by variable-speed wind turbines among the installed wind turbines will require further development of control methods. Power electronic converters are widely used to improve power quality in conjunction with the integration of variable speed wind turbines into the grid. READ MORE

  5. 4. Digital Design Flow Techniques and Circuit Design for Thin-Film Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Suman Balaji; [2020]
    Keywords : Digital design flow; Circuit design; Thin-film transistors; Technology and Engineering;

    Abstract : Thin-Film Transistor (TFT) technology refers to process and manufacture transistors, circuits, Integrated circuits (ICs) using thin-film organic or metal-oxide semiconductors on different substrates, such as flexible plastic foils and rigid glass substrates. TFT technology is attractive and used for applications requiring flexible, ultrathin ICs to enable seamless integration into devices. READ MORE

  6. 5. 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.
