  1. 16. RF Energy Harversting : Design and implementation of an RF energy harvesting system for SoC

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Erlend Sanden; [2019]
    Nyckelord :Power management; radio frequency harvesting; low power device;

    Sammanfattning : This assignment was given by Nordic Semiconductor. In this project a radio frequency energy harvesting system able to harvest ambient power at 900 MHz (GSM) was simulated and designed. A Villard voltage multiplier, boost converter and power management circuit was implemented for the harvesting system. LÄS MER

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

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

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

    Sammanfattning : 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. LÄS MER

  4. 18. Feasibility of DC microgrids for rural electrification

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Krishna Prasad Vijayaragavan; [2017]
    Nyckelord :Solar PV; Microgrids; DC; Low Voltage DC; Rural electrification; Pvsyst; Simulink; Power converters; boost converter; MPPT; performance ratio.;

    Sammanfattning : DC system and DC microgrids are gaining popularity in recent times. This thesis suggests a method to state the workability of a DC based PV system using the softwares Simulink, PVsyst and HOMER. The aims of this project include suggesting a DC based architecture, finding out the performance ratio and a cost analysis. LÄS MER

  5. 19. Smart and flexible capacitor charger for warm environments

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Tobias Rydberg; [2016]
    Nyckelord :;

    Sammanfattning : A studio camera flash system being developed by Eascal AB needs a capacitor charging power supply (CCPS) that can work in a hot environment without problems and also not emit too much heat itself. The CCPS needs to be able to operate from battery power as well as net power, so called off-line, and to charge a capacitor to between 0-400 V. LÄS MER

  7. 20. Impact Study: Photo-voltaic Distributed Generation on Power System

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Smrutirekha Sahoo; [2016]
    Nyckelord :DC-AC inverter; DC-DC boost converter; Dynamic PV model; Grid-connected PV system; Harmonic distortion; LV grid-modelling; Overvoltage; THD; Voltage unbalancing; VSI;

    Sammanfattning : The grid-connected photo-voltaic (PV) system is one of the most promising renewable energy solutions which offers many benefits to both the end user and the utility network and thus it has gained the popularity over the last few decades. However, due to the very nature of its invariability and weather dependencies, the large scale integration of this type of distributed generation has created challenges for the network operator while maintaining the quality of the power supply and also for reliable and safe operations of the grids.
