  3. 2. A New Paradigm for Large Brushless Hydrogenerators : Advantages Beyond the Static System

    Författare :Jonas Kristiansen Nøland; Urban Lundin; Phil Mellor; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brushless exciters; Rotating exciters; Permanent Magnet Machines; Synchronous Generator Excitation; Thyristor Rectifiers; Chopper Rectifiers; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The grid code, FIKS, from the Norwegian transmission system operator (TSO), Statnett, states that synchronous generators > 25MVA, must have a static excitation system. However, an improved brushless excitation system is in operation on some commercial power plants (36MVA, 93.75rpm & 52MVA, 166. LÄS MER

  4. 3. Rectifiers in CMOS for RFID Applications

    Författare :Hans Rabén; Fredrik Jonsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Radio frequency identification (RFID) technology is used today in a number of differentareas, such as logistics, supply chain management, access control and environmentalmonitoring. The ability to store information electronically in small tags that can be readwirelessly has great potential. LÄS MER
