  4. 17. Enhanced Dielectric Response Methods for the Characterization of Dielectric Materials

    Author : Jing Hao; Nathaniel Taylor; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FDS; non-contact; dielectric response; combined AC and DC; space-charge polarization;

    Abstract : Dielectric response measurement is widely used for condition assessment of high voltage equipment and for characterizing candidate materials. Measurement with high accuracy and reliability is important in all stages of the lifetime of high voltage equipment, from manufacture to replacement decision. READ MORE

  5. 18. Ultra-fast electromechanical commutation switch for hybrid breakers

    Author : Mrunal Parekh; Marley Becerra Garcia; Christian Franck; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In a power system with the ability to integrate geographically spread diverse renewable energy sources, there is a need for efficient control of the power flow and effective power transmission. Power electronics can provide this controllability, at the expense of conductive losses in the used components. READ MORE

  6. 19. Design of Thermoelectric Generators for Automotive EGR Applications

    Author : Olle Högblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact resistances; Exhaust gas heat recovery; Thermoelectrics; CFD;

    Abstract : Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas recirculation (EGR) cooler using thermoelectric generators (TEG). READ MORE

  7. 20. Integration of Two-Dimensional Materials for Electronics and Photonics

    Author : Arne Quellmalz; Kristinn Gylfason; Frank Niklaus; Cedric Huyghebaert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Two-dimensional (2D) materials with a thickness on the atomic scale promise to continue the trend of increasing performance in electronics, photonics, and sensing. However, despite record-breaking demonstrations of individual devices, the commercial exploitation of 2D materials is still limited. READ MORE
