  1. 16. Övervakningssystem för vindkraftverk : Monitoring system for wind turbines

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Mariam Jebur; [2016]
    Nyckelord :Monitoring system; wind turbines; övervakningssystem; vindkraftverk; teknik; sensorer; step-down;

    Sammanfattning : This report describes how a new and modern monitoring system is crea- ted for a wind turbine. Elvira Vind AB is a company that has an old operating surveillance system manufactured in 1992. A need has arisen with the owner of the company and are looking for a simple and smooth system that monitors the situation in a wind turbine. LÄS MER

  3. 17. FPGA Software Development for Control Purposes of High-Frequency Switching Power Converters

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Författare :Gagner Anton; Nino Hebib; [2016]
    Nyckelord :FPGA; VHDL; C; Converter; Step-down; Buck; DC DC; Closed-loop; Control; Protocol;

    Sammanfattning : FPGA stands for Field Programmable Gate Array and it is a technology that has been on the rise the last decades. With a decrease in size of the logic elements commercially available products have started to have more built-in functionality in one package and by being reprogrammable makes the system a powerful competitor among its neighbors.

  5. 19. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System

    Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Ye Xu; [2016]
    Nyckelord :contactless energy transfer; transformer power loss; iron loss; iron loss model; rotary transformer; three-phase transformer; finite element method; COMSOL Multiphysics; electrical steel; electrical steel manufacturing process;

    Sammanfattning : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. LÄS MER

  7. 20. Refrigeration system performance using alternative refrigerants
