  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. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Umar Farooq; [2023]
    Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

  4. 3. Competitor analysis of the synchronous machines market : A study of how manufacturers differentiate themselves from each other with unique value propositions

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

    Author : Fredrick Fager; Jiyan Kösanlioglu; [2023]
    Keywords : Synchronous machines; synchronous motors; synchronous generators; competitor analysis; value proposition; Synkronmaskiner; synkrona motorer; synkrona generatorer; konkurrentanalys; värdeerbjudande;

    Abstract : This report highlights the market for synchronous machines and examines the current situation. Today, the world demands higher volumes of electrical power that is cleaner, more efficient and generated from fossil-free sources. This increases the importance of using efficient and modern that minimise energy losses. READ MORE

  5. 4. Control Aid Implementation -Modelling and simulation of triple extruder-

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Karl Langsér; [2023]
    Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE
