  1. 16. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Farhan Akram; [2021]
    Nyckelord :SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Sammanfattning : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. LÄS MER

    Sammanfattning : Denna kandidatrapport behandlar ett arbete resulterande i en ökning av hållfastheten hos en skidbalk ingående i bandvagnen BvS10. Projektet har utförts på uppdrag av BAE Systems Hägglunds under deras SIRIUS-samarbete med Luleå tekniska universitet. LÄS MER

  4. 18. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Johannes Jonsson; Anton Andersson; [2021]
    Nyckelord :Vibratory driving; sheet pile; Technology and Engineering;

    Sammanfattning : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. LÄS MER

  5. 19. The change agent’s role in accelerating sustainability : A case study in a construction company

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Henrik Åkesson; Ulrika Zenk Conte; [2021]
    Nyckelord :change management practices; change agent; dual operating system; change resistance; sustainability;

    Sammanfattning : The main purpose of this thesis has been to study the change agent’s role in accelerating sustainability in the construction sector. A case study was conducted in a large construction company (~9000 employees) with an ambitious sustainability profile. LÄS MER

  7. 20. Torque-Based Load Estimation for Passenger Vehicles

    Master-uppsats, Linköpings universitet/Reglerteknik
