  1. 1. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

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

    Author : Fabian Tidner; [2023]
    Keywords : Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

  3. 2. Application of PSS to Improve the Stability of a Power System With a High Penetration of Renewable Energy

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

    Author : Sixten Norelius; Ylva Persson; [2023]
    Keywords : ;

    Abstract : Unlike traditional power generation composed of synchronous generators, renewable energy in theform of solar and wind power does not add inertia to power systems. Therefore, as increasedproportions of renewable energy are added, the dynamics of the power system will be affected. READ MORE

  4. 3. Engineered imaging scaffolds for cryo-EM of small proteins of interest

    University essay from KTH/Proteinvetenskap

    Author : Oscar Friberg; [2022]
    Keywords : Protein structure determination; single-particle cryo-EM; imaging scaffold; size limitation problem; affibody; YgjG.;

    Abstract : Strukturbestämning av proteiner är viktigt för att kunna förstå deras funktion och en snabbt utvecklande metod inom fältet är kryoelektronmikroskopi. Storleksbegränsningar förhindrar en bredare applikation av metoden eftersom små proteiner har för låg signal i förhållande till bakgrund för att kunna visualiseras som enstaka partiklar i elektronmiksoskopibilder.

  5. 4. Design and Verification of An Energy-Efficient Edge-Pursuit Comparator

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

    Author : Haiqin Xie; [2022]
    Keywords : analog to digital converter ADC ; SAR; comparator; edge-pursuit comparator EPC ; edge-pursuit comparator enhanced with capacitor EPCC ; energyefficient.; analog till digital omvandlare ADC ; SAR; komparator; edge-pursuit komparator EPC ; edge-pursuit komparator förbättrad med kondensator EPCC ; energieffektiv.;

    Abstract : With the rapid development of mobile communication, sensors, and biomedical in recent years, the demand for accurate data information, highquality audio and image has become much more significant, which requires a high-precision Analog to Digital Converter (ADC) to process weak analog signals. As one of the core modules of ADC, the comparator’s precision, speed, stability, and noise play a key role in the performance of the whole circuit. READ MORE
