  1. 1. Multilevel Power Converters with Smart Control for Wave Energy Conversion

    Author : Deepak Elamalayil Soman; Mats Leijon; Jan Isberg; Sebastain Nielebock; Gopal Mondal; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Multilevel power converter; FPGA control; Wave Energy; Three-level boost converter; Three-level buck-boost converter; Variable-renewable-energy; Three-level neutral point clamped inverter; Linear generator; DC-link; AC2AC direct converter; Modular multilevel converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The main focus of this thesis is on the power electronic converter system challenges associated with the grid integration of variable-renewable-energy (VRE) sources like wave, marine current, tidal, wind, solar etc. Wave energy conversion with grid integration is used as the key reference, considering its high energy potential to support the future clean energy requirements and due the availability of a test facility at Uppsala University.

  2. 2. Grid Integration and Impact of a Wave Power System

    Author : Arvind Parwal; Cecilia Boström; Damir Šljivac; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ANN; buck-boost converter; current control; energy storage system; force control; flicker; FPGA control; grid integartion; harmonics; linear generator; PHIL; microgrid; voltage variation; wave energy; WEC; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Increasing energy consumption and concern for carbon emissions has boosted the demand for renewable energy production. The focus on renewable energy has gained much attention in wind, solar, hydro and wave power generations. Wave power has great potential due to its high energy density but there are challenges as well. READ MORE

  3. 3. DC-DC Converters - Dynamic Model Design and Experimental Verification

    Author : Bengt Johansson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; buck; dc-dc converter; modeling; audio susceptibility; current-mode control; load current; gain scheduling; current transformer; experimental verification; Electronics and Electrical technology; Automation; Elektronik och elektroteknik; Elektroteknik; Electrical engineering; reglerteknik; robotteknik; Automatiska system; control engineering;

    Abstract : To obtain high performance control of a dc-dc converter, a good model of the converter is needed. The load usually affects the dynamics and one way to take this into consideration is to regard the load as a part of the converter. The load is often the most variable part of this system. READ MORE

  4. 4. Modelling and Interference Analysis of AC-DC Converters for Immunity to Voltage Disturbances up to 150 kHz

    Author : Selcuk Sakar; Sarah Rönnberg; Math Bollen; Sjef Cobben; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AC-DC power converters; electromagnetic compatibility EMC ; high frequency disturbances; supraharmonics; switching converters; interharmonics; conducted disturbances; Electric Power Engineering; Elkraftteknik;

    Abstract : The function of electrical and electronic equipment is challenged by the high frequency emission originated from the more use of switching-based power electronic equipment and Power line communication (PLC) signaling. Investigations have shown that interferences occur in the frequency range between 2 kHz and 150 kHz, e.g. READ MORE

  5. 5. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Author : Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Abstract : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. READ MORE
