  1. 1. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Longgang Su; [2022]
    Nyckelord :Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

    Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER

  3. 2. Performance Evaluation of Modular Multilevel Converters for Photovoltaic Systems

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Nyckelord :Modular Multilevel Converters; Converters; Power Converters; Photovoltaics; Photovoltaic systems; Half-bridge MMC; MMC; Full bridge MMC; Full bridge modulation;

    Sammanfattning : Modular Multilevel Converters (MMCs), over recent years, have gained popularity in high-voltage(HV) and medium-voltage (MV) applications due to their high reliability. Also, with the rapid growth of solar photovoltaics (PV) and energy storage systems, there is a high demand for efficient and reliable power converter solutions. LÄS MER

  4. 3. An MMC-based topology with Dual-Active-Bridge power channels for load balancing in 50 Hz-railway applications

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

    Författare :Andreas Zafeiropoluos; [2017]
    Nyckelord :Power electronics; STATCOM; MMC; power channel; power quality; negativesequence compensation; high-speed trains;

    Sammanfattning : The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. LÄS MER
