    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. MANGO - Generating 2D-Magnetic Field Maps From Normal-Conducting Magnets Of Experimental Areas

    Master-uppsats, KTH/Fysik

    Sammanfattning : This thesis discusses the development of MANGO, a tool created to model normal-conducting magnets which were installed in the 1970s in the experimental areas at CERN, and store their analysis. MANGO formulates an answer to two problems faced by the physicists of the Beam Department when they model a beam line: first, how to produce new magnetic field maps and, second, how to easily access existing ones? It contains a multi-use package that offers an automated process to produce magnetic field maps from finite-element models of magnets. LÄS MER

  4. 3. An assessment of the surrogate host metagenome-assembled genome decontamination for non-model host organisms : Proof-of-concept

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :André Bourbonnais; [2023]
    Nyckelord :;

    Sammanfattning : In this study, a novel method has been assessed to bridge the gap between bioinformatics and ecological conservation efforts to gain evidence to further base conservational plans on. Herein, the validity of using a provisional host metagenome-assembled metagenome to decontaminate the data from host contamination was concluded. LÄS MER

  5. 4. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Ken Dahl; [2023]
    Nyckelord :PMSM; permanent magnet synchronous motor; synchronous motor; black-box modelling; black-box models; thermal modelling; lumped parameter thermal network; LPTN; electric machine; EM; EV; electric vehicle; winding;

    Sammanfattning : A significant challenge with permanent magnet synchronous motors (PMSMs) is thermal management. Thermal stress can lead to irreversible damage to components, and to enable efficient cooling, a thermal model is needed. LÄS MER

  7. 5. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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