  1. 1. Isolated Single-Stage Interleave Resonant PFC Rectifier with Active and Novel Passive Output Ripple Cancellation Circuit

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Abidemi Oluremilekun Eleyele; [2020]
    Nyckelord :single-stage AC DC converter; bridgeless power factor correction PFC rectifier; active passive ripple cancellation; zero current switching ZCS ; zero voltage switching ZVS ; Electric vehicle EV charger; LLC;

    Sammanfattning : With the increasing demand for fast, cheaper, and efficient power converters come the need for a single-stage power factor correction (PFC) converter. Various single-stage PFC converter proposed in the literature has the drawback of high DC bus voltage at the input side and together with the shift to wide bandgap switches like GaN drives the converter cost higher.

    Master-uppsats, KTH/Elkraftteknik

    Författare :Olof Brandt Lundqvist; [2017]
    Nyckelord :;

    Sammanfattning : Wave power is an energy source which could make a decisive difference in thetransition towards a more sustainable energy sector. The growth of wave powerproduction has however not been as rapid as the growth in other renewableenergy fields, such as wind power and solar power. LÄS MER

  4. 3. Power Electronic Stages for a TFPMSM in Wave Power Applications

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Gustaf Falk Olson; [2016]
    Nyckelord :transverse flux permanent magnet synchronous machine TFPMSM ; active rectifier; direct drive wave energy converter; feedback linearization; cascaded PID controller.;

    Sammanfattning : Direct drive wave energy conversion systems have been identified as a potentially major contributor to the world’s energy demands, forecasting shares of up to 25 % of the energy mix. Anders Hagnestål conducts research at the Royal Institute of Technology where a novel linear transverse flux permanent magnet generator is developed. LÄS MER

  5. 4. Development of EMT Simulation Model to Use RMS Control Model

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Priya Kalikavunkal; [2016]
    Nyckelord :;

    Sammanfattning : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. LÄS MER

  7. 5. 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.
