  1. 1. Energy harvesting för sensorer i tung industriell miljö

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Elias Tångås; [2023]
    Nyckelord :;

    Sammanfattning : Energy harvesting essentially involves extracting energy from processes that generate losses in theform of heat, vibrations, radiation, etc, and converting it into electrical energy that can be used topower sensors or other electrical systems. A customer of Knightec Örnsköldsvik wants to develop measurement equipment using sensors in a demanding industrial environment with rotating machines that does not allow wired energy or communication transfer.

  3. 2. Laminated HZO on InAs: A study of as-deposited ferroelectricity

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :André Andersen; [2022]
    Nyckelord :Ferroelectricity; HZO; InAs; III V; As-deposited ferroelectricity; BEOL; Nanoelectronics; Nanoprocessing; Nanotechnology; ALD; MOSCAP; Memory Technology; Technology and Engineering;

    Sammanfattning : As the limits of transistor feature size scaling is reaching its saturation, new innovations are needed to prevent performance loss. High performance transistors on the III/V semiconductor platform implemented with ferroelectric oxides might in the future satisfy this demand. LÄS MER

  4. 3. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules

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

    Författare :Lingyu Chen; [2022]
    Nyckelord :Modular multilevel converters MMC ; interleaved half-bridge submodule; interleaved converters; power loss calculation; converter efficiency; converter dimensions; Modulära multilevel-omvandlaren; interfolierad halvbrygga submodul; interfolierade omvandlare; effektförlustberäkning; omvandlareffektivitet; omvandlardimensioner;

    Sammanfattning : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. LÄS MER

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

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

    Författare :Haiqin Xie; [2022]
    Nyckelord :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.;

    Sammanfattning : 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. LÄS MER

  7. 5. Överspänningsskydd

    M1-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jesper Hilleberg; Sam Falakeh; [2021]
