  3. 3. Cooling Strategies for Wave Power Conversion Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Antoine Baudoin; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Abstract : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

  4. 4. Design and Evaluation of a Permanent Magnet Generator for Wave Power Applications

    University dissertation from Chalmers University of Technology

    Author : Pinar Tokat; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; wave energy; permanent magnet machine; energy efficiency;

    Abstract : In this thesis, the performance of a wave energy converter (WEC) consisting of a single point absorber wave device coupled with a radial flux permanent magnet generator is investigated. The available wave power and the energy potential are studied for a specified wave climate and the electric power output is determined through an analytical buoy movement simulation. READ MORE

  5. 5. Wave Energy Conversion Linear Synchronous Permanent Magnet Generator

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
