  4. 2. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

    Author : Shuang Zhao; Chandur Sadarangani; Sigurd Övrebö; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

    Abstract : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. READ MORE

  5. 3. Investigation of AC electrical machine stators with fractional conductor windings

    Author : Henrik Grop; Juliette Soulard; Yujing Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; windings; leakage; large machines; induction motor construction; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Industry always searches the least expensive solution for a machine design. Therefore, there is a need for integrating different customer ordered machines within the same frame, while keeping the foundation of the mechanical design constant. READ MORE

  6. 4. Spatial and temporal metrology of intense attosecond pulses

    Author : Helene Coudert-Alteirac; Atomfysik; []
    Keywords : Ultrafast optics; High-order harmonic generation; Filamentation; Attosecond; Femtosecond; Extreme ultraviolet; Wavefront measurement; Optical metrology; XUV optics; interferometry; Pump-probe; Fysicumarkivet A:2018:Coudert-Alteirac;

    Abstract : Attosecond pulses are short enough to capture the electronic dynamics in atoms and molecules. The work presented in this thesis deals with the generation and optimization of attosecond extreme-ultraviolet (XUV) pulses. READ MORE

  7. 5. Linear wave energy converter : Study of electromagnetic design

    Author : Erik Lejerskog; Mats Leijon; Giuseppe Passoni; Uppsala universitet; []
    Keywords : Wave energy; permanent magnets; linear generator; closed stator slots; offshore experiments;

    Abstract : The thesis presents results from synchronous linear wave energy converters developed at Uppsala University. A study is done on closed stator slots and a study presenting offshore data focusing on the power absorption from a wave energy converter (WEC). READ MORE
