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

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

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

    Abstract : 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. READ MORE

  3. 17. Reliability Study of SiC-Based Power Electronic Devices in DC-DC Converter Used in Heavy-Duty Electric and Hybrid Vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sanaz Namayantavana; [2017]
    Keywords : ;

    Abstract : A DC-DC converter is used in electrified and hybrid vehicles to supply powerto the low voltage (ex. 24V) system including headlights, horn, air conditioningsystem, wipers, radio, etc. The converter is fed from a high voltage (ex. 650V)battery, which is available in electric/hybrid vehicles, and transfers a relativelyhigh power.

  4. 18. FPGA Software Development for Control Purposes of High-Frequency Switching Power Converters

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

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

    Abstract : 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. Modelling and Design of Digital DC-DC Converters

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Author : Hiwa Mobaraz; [2016]
    Keywords : DC-DC; Buck; Boost; Digital; Converter; Design; Comparision;

    Abstract : Digital Switched mode power supplies are nowadays popular enough to be the obvious choice in many applications. Among all set-up and control techniques, the current mode DC-DC converter is often considered when performance and stability are of interest. READ MORE

  6. 20. High frequency dc/dc power converter with galvanic isolation

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Author : André Van Der Kogel; Niklas Österlund; [2016]
    Keywords : ;

    Abstract : There is a steady demand to increase the efficiency and raise the power density of power converters. This trend is desired since it leads to reduced size of the converter. The purpose of this thesis is to investigate materials, topologies, core structure and then build a prototype to demonstrate the result. READ MORE
