  1. 1. Transmission Modeling for Optimization of Electric Powertrains

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Jacob Lundborg; Johanna Hulth Olsson; [2021]
    Nyckelord :Electric vehicle transmission; multi-objective optimization; mass minimization; power loss minimization; Technology and Engineering;

    Sammanfattning : Over the last decade, the number of electric vehicles (EVs) on the world's roads has rapidly increased. Optimization of power consumption in electric powertrains will, therefore, lead to reduced energy usage in the road transport sector. LÄS MER

  4. 3. New Topology for STATCOM

    Master-uppsats, KTH/Elkraftteknik

    Författare :Marta Ibáñez Sánchez; [2017]
    Nyckelord :STATCOM; Modular Multilevel Converter; Chain-Link; negative sequence capability; common dc-link; bi-directional switches;

    Sammanfattning : Static compensators (STATCOM) based on high-power converters are widely used for utilitiesand industrial applications in order to enhance the power system reliability. Nowadays,the Chain-Link Modular Multilevel Converter is the best solution for such applications,providing high eciency and reliability, and good harmonic performance. LÄS MER

  5. 4. Hydraulic Energy Efficiency of Concepts on an Articulated Hauler : Design and evaluation of different hydraulic concepts with focus on energy efficiency

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska fakulteten

    Författare :André Arana Escobedo; Oskar Gunnarsson; [2015]
    Nyckelord :;

    Sammanfattning : This master's thesis has evaluated dierent system designs for the hydraulic system on an articulated hauler at Volvo Construction Equipment (CE). The current system suers from great losses when running on low pump displacement settings. This is due to large installed displacements as a result of regulations and market demands. LÄS MER
