  2. 2. Development of the Winding Geometry for an Efficient Wave Power Generator

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Thomas Wall; [2017]
    Keywords : ;

    Abstract : A method for twisting a stranded cable in orderto reduce losses due to circulating currents is investigated. Atheoretical model connecting the voltages over individual strandsto the magnetic flux through the cable is presented. A modelsimplifying the geometry of the cable is developed. READ MORE

  3. 3. ANALYSIS, IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF A PHASE SHIFTED PWM CONTROL SYSTEM FOR A MODULAR MULTILEVEL CONVERTER

    University essay from KTH/Elektrisk energiomvandling

    Author : Juan Colmenares; [2011]
    Keywords : ;

    Abstract : Nowadays, it is problematic to connect only one power semiconductor switch directly to the grid due to the high voltage range. In order to solve this difficulty, a new type of power converter has been introduced as a solution in high power applications. READ MORE
