  1. 21. A comparison of different connection techniques for thermoelectric generators in vehicle waste heat recovery

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Björn Andersson; [2013]
    Nyckelord :Waste heat recovery; thermoelectric generator; maximum power point tracking; Technology and Engineering;

    Sammanfattning : Increasing demand for lower fuel consumption increases the importance of a higher total energy efficiency in trucks. Since the efficiency of a modern diesel engine is in the range of 40 %, large amounts of waste heat are produced. Recovering this energy can be done with thermoelectric generators. LÄS MER

  3. 22. Modelling of Photovoltaic power plantsin SIMPOW

    Master-uppsats, KTH/Elektriska energisystem

    Författare :Leila Manshaei; [2013]
    Nyckelord :;

    Sammanfattning : This master thesis project represents an improved model of a grid connected three phase, singlestage PV system implemented in SIMPOW program. The proposal model consists of a PVgenerator employing a PWM converter in order to interface the AC network. LÄS MER

  4. 23. Solutions for Indoor Light Energy Harvesting

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Stefano Vignati; [2012]
    Nyckelord :;

    Sammanfattning : Energy harvesting (EH) was born few decades ago and evolved during the years, however only recently has found more applications thanks to the advent of wireless sensor networks and the developments in microchips technology. This thesis investigates energy harvesting potentialities, in particular those related to solar harvesting in indoor applications. LÄS MER

  5. 24. MCU Controlled DC-DC Buck/Boost Converter for Supercapacitors

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jorge Querol Borràs; [2012]
    Nyckelord :;

    Sammanfattning : This work is focused on DC to DC conversion, what is a crucial function to enable the use of supercapacitors for energy storage. A theoretical study and comparison of methods, algorithms and techniques for software controlled DC-DC converters have been used to develop a system what can step up or down a DC variable voltage and transform it into a steady state voltage.

  7. 25. Multi-Source Energy Harvesting for Wireless Sensor Nodes.

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Kai Kang; [2012]
    Nyckelord :;

    Sammanfattning : The past few years have seen an increasing interest in the development of wireless sensor networks. But the unsatisfactory or limited available energy source is one of the major bottlenecks which are limiting the wireless sensor technology from mass deployment. LÄS MER
