  1. 1. Design and construction of a bidirectional DC/DC converter

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alexander Wallberg; [2019]
    Keywords : Converter; DCDC; Energy storage; Single-phase; Omvandlare; DCDC; Energilager; Single-phase;

    Abstract : A four quadrant general single-phase bi-directional DC/DC converter was designed and constructed for high effect systems. The target application for the DC/DC converter was to be used to transfer energy between different energy storages, a miniature DC power grid and the high voltage AC power city grid. READ MORE

  2. 2. Improving silage digestibility with fibrolytic enzymes

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Thomas Eliasson; [2018]
    Keywords : ensilage; smältbarhet; fiber; växtfiber;

    Abstract : In Sweden, the dairy cow is an important producer of both milk and meat. The production is highly dependent on forage as a source of nutrients for the cow. Ruminants are excellent converters of plant material that otherwise is highly indigestible for humans. READ MORE

  3. 3. Study and Design of a DC-DC Converter for Third Generation Solar Cells

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

    Author : Sturla Lange; [2018]
    Keywords : Third-generation solar cell; Dye-sensitized solar cell; DC-DC converter; Boost converter.; Tredje generationens solceller; Dye-sensitized solceller; DC-DC-omvandlare; Boost-omvandlare.;

    Abstract : The perceived battery capacity of battery-powered devices can be increased by harvesting energy from readily available sources. Third generation solar cells are a good candidate for this purpose since they can be integrated with these battery-powered devices and harvest power from diffused light. READ MORE

  4. 4. Experimental investigation and analysis of a distributed MPPT system for a small-scale photovoltaic installation

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

    Author : Moises Hasbum Casanova; [2018]
    Keywords : ;

    Abstract : The focus of this thesis is the integration of distributed MPPT solutionswith existing photovoltaic systems. Power electronics are used to optimizethe output power from solar panels. Different topologies are used where adc/dc converter carries out the optimization task for one or more strings ofsolar panels. READ MORE

  5. 5. An Investigation on PVDF Piezoelectric Elements and Linear Array Transducers

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Ali Alkhudri; [2017]
    Keywords : Ultrasonic Transducer; Piezoelectric Element; PVDF; Frequency; Ultrasound Wave Penetration; PZT; Acoustic Impedance; raw data; linear array transducer; Technology and Engineering;

    Abstract : Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. READ MORE
