  1. 21. Design of a Real-Time Model of a Photovoltaic Panel

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

    Författare :Markus Fjällid; [2015]
    Nyckelord :Power electronics; Photovoltaic panel; Buck converter; Interleaved switching;

    Sammanfattning : Photovoltaic panels are widely used to harvest solar energy. In the general application the panels are connected to an inverter that allows the power to be feed to the grid. The possibility to emulate a photovoltaic panel in a laboratory environment simplifies the development of inverters. LÄS MER

  3. 22. Designing a brushed DC motor controller : Laying the framework for a lab experiment involving position control with current feedback

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Björn Franzén; [2015]
    Nyckelord :DC motor control; DC motor; DC motor position control; h-bridge; synchronous buck converter; torque feedback; current feedback; switched DC motor controller;

    Sammanfattning : In order to provide the means to set up a control theory lab experiment involving position control of a brushed DC motor with current feedback, a pulse-width modulated motor controller was designed. The output voltage is controlled by an analog reference signal and the magnitude of the output current and voltage are measured and output. LÄS MER

  4. 23. Active rectification and control of magnetization currents in synchronous generators with rotating exciters : Implementation of the SVPWM algorithm using MOSFET technology

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Tomas Johansson; [2015]
    Nyckelord :rectification; SVPWM; space vector pulse width modulation; current control; active rectification; three phase;

    Sammanfattning : This thesis aims to design and build a power electronics system for the rectification and control of magnetization currents in synchronous generators with rotating exciters.The rotating exciter provides three-phase AC while the generator rotor needs DC with a high degree of control.

  5. 24. PFC-design for frequency converter

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

    Författare :David Kantzon; [2015]
    Nyckelord :;

    Sammanfattning : This thesis deals with power factor correction for three-phase systems. A boost-buck topology was described, modeled and then simulated in MATLAB/Simulink. The simulation results show that the system provides a power factor over 99% over the tested power output range. LÄS MER

  7. 25. Input Filter to Prevent Line Oscillations in Buck Converter

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Raghavendra Pappala; Raghavender Reddy Naredla; [2013]
    Nyckelord :Filter design; Line Oscillations; Buck Converter; Damping; Passive Filter;

    Sammanfattning : Micropower AB is a company that design and produce battery chargers for heavy vehicles. Buck converters are used in some chargers as they provide a regulated output voltage. In buck converter, transistor acts as a switch which is controlled by Pulse Width Modulated signal. LÄS MER
