    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The purpose of this licentiate thesis is to research a few key concepts which are important in the development of high efficiency electric drives. The selected research method is quantitative, the raw data have been collected from real world measurements, both from powerlab and from train. READ MORE

  5. 3. Power control strategies for renewable energy systems : The inverter's role in future power systems

    Author : Sara Anttila; Cecilia Boström; Sandra Eriksson; Lena Max; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy systems; Grid-connection; Inverter; Power control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Connecting more non-dispatchable renewable energy sources (RESs) will result in a higher power variability and a lower system inertia when the synchronous generators are replaced by inverter-connected RES. Inverter control can be divided in three categories: grid-following, grid-forming (GFM) and grid-supporting. READ MORE

  6. 4. Energy Efficiency Comparison Between Two-level and Multilevel Inverters for Electric Vehicle Applications

    Author : Oskar Josefsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicle EV ; Drive Cycle; Plug-in Electric Vehicle PEV ; Multilevel Inverter MLI ; Two-level Inverter TLI ; Efficiency.; Integrated Charger;

    Abstract : In order to contribute to the development of energy and cost efficient electric vehicles, a thorough analysis of two different electric converter topologies is performed, considering different drive cycles and different control strategies. In the electric vehicles available on the market today, a high voltage (200−400 V ) battery pack composed of several battery modules is connected to one or more inverters which create AC voltages to the electric propulsion machines.
