  1. 1. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fan Yang; [2023]
    Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

    Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

  3. 2. Influence of structural and materials properties on the flexural strength of laminated high-density cellulose fiberboards

    University essay from KTH/Hållfasthetslära

    Author : Ola Serck; [2021]
    Keywords : ;

    Abstract : Laminated pressboard is a structural electrical insulation material used in power transformers. Typical applications are areas in the power transformers where high mechanical forces are present such as pressrings or winding tables and cleats which support the electrical cables connecting the transformer windings to tap-changes and bushings.

  4. 3. A micro-CT investigation of density changes in pressboard due to compression

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Johan Stjärnesund; [2018]
    Keywords : Micro computed tomography; μCT; pressboard; density; densification;

    Abstract : Pressboard, a high-density cellulose-based product, is used both as load bearing structures and dielectric insulation in oil-filled power transformers. During transformer operation, mechanical forces and vibrations are applied on the material. READ MORE

  5. 4. High frequency dc/dc power converter with galvanic isolation

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Author : André Van Der Kogel; Niklas Österlund; [2016]
    Keywords : ;

    Abstract : There is a steady demand to increase the efficiency and raise the power density of power converters. This trend is desired since it leads to reduced size of the converter. The purpose of this thesis is to investigate materials, topologies, core structure and then build a prototype to demonstrate the result. READ MORE

  6. 5. Analysis of an induction regulator for power flow control in electric power transmission systems

    University essay from Institutionen för fysik, kemi och biologi

    Author : Anna Guldbrand; [2005]
    Keywords : Power flow control; Phase shifting; Induction regulator; Gadolinium;

    Abstract : Controlling the power flow in transmission systems has recently gained increased interest. The difficulties of building new lines and the pressure of having a high utilization of existing assets, makes the flexibility of grid systems increasingly important. READ MORE
