  1. 1. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

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

    Author : Jiale Deng; [2023]
    Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

  3. 2. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    University essay from Karlstads universitet

    Author : Marcus Roseen; [2023]
    Keywords : ;

    Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

  4. 3. Data Centres as Prosumers: A Techno-Economic Analysis

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jeremy Ericsson Sintong; [2023]
    Keywords : Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Abstract : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. READ MORE

  5. 4. Superconducting gates for InP HEMTs

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Alveteg; [2023]
    Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

  6. 5. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lukas Strandberg; Madeleine Sandberg; [2023]
    Keywords : Vehicle-to-Grid; Grid flexibility; Capacity markets; Barriers; Fordon-till-nätteknologi; Elnätsflexibilitet; Kapacitetsmarknader; Barriärer;

    Abstract : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. READ MORE
