  2. 6. Electromagnetic Dispersion Modeling and Analysis for Power Cables

    Author : Stefan Gustafsson; Sven Nordebo; Alexander Nosich; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; power cable; electromagnetic model; dispersion relation; asymptotic analysis; sensitivity analysis;

    Abstract : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. READ MORE

  4. 7. Modeling colloidal nanoparticles: From growth to deposition

    Author : Joakim Löfgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gold; DLVO; thermodynamics; van der Waals; density functional theory; modeling; deposition; dispersive interactions; anisotropic; colloidal nanoparticles; nanorods;

    Abstract : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. READ MORE

  5. 8. MOSFET Modeling Aimed at Minimizing EMI in Switched DC/DC Converters Using Active Gate Control

    Author : Andreas Henriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic interference; Semiconductor device modeling; Adaptive control; MOSFET switches; Electromagnetic compatibility; State space methods; DC-DC power conversion; Power semiconductor diodes; Semiconductor device measurements;

    Abstract : This thesis deals with electromagnetic interference that can arise from switched DC/DC-converters intended for low-power applications, e.g. within the telecom or automotiveindustry. READ MORE

  6. 9. Electromagnetic dispersion modeling and analysis for HVDC power cables

    Author : Stefan Gustafsson; Sven Nordebo; Martin Norgren; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HVDC power cables; electromagnetic model; TDR measurement; sensitivity analysis; dispersion relation; propagation constant; low-frequency asymptotics;

    Abstract : Derivation of an electromagnetic model, regarding the wave propagation in a very long (10 km or more) High Voltage Direct Current (HVDC) power cable, is the central part of this thesis. With an existing “perfect” electromagnetic model there are potentially a wide range of applications. READ MORE

  7. 10. Electric Traction Machine Design for an E-RWD Unit

    Author : Francisco Marquez; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Traction Machines; Permanent Magnet Machines; Laminated Winding Machines; Hybrid Electric Vehicles; Electrical Machine Design; Electromagnetic Modeling; Thermal Modeling; Finite Element Analysis.;

    Abstract : Since the first generation of the Toyota Prius was introduced in December 1997, the number of Hybrid Electric Vehicles (HEVs) and pure Electric Vehicles (EVs) available in the market has increased substantially. The growing competition existent puts high demands on the electric system as well as the rest of the vehicle. READ MORE
