  1. 1. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Kaj Törngren Sato; [2023]
    Nyckelord :Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

    Sammanfattning : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. LÄS MER

  3. 2. Undersökning av induktionshärdning för automatiserad processtyrning

    Master-uppsats, KTH/Industriell produktion

    Författare :Morgan Sten; [2022]
    Nyckelord :;

    Sammanfattning : Denna rapport granskar hur härdzonen hos vevaxlar påverkas av ändrade processparametrar i induktionshärdningsprocessen. Uppvärmningsdelen av härdningsprocessen har studerats med en infraröd värmekamera för att se hur temperaturkurvorna varierar när processparametrar ändras. LÄS MER

  4. 3. Boost Converter Inductor Design for High-Power Fuel Cells Using Pareto Optimisation for Single and Coupled Cores

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

    Författare :Lucas Tunelid; [2022]
    Nyckelord :Fuel Cells; Interface Converters; Inductor Design; Mutiobjective Optimisation; Bränsleceller; Gränsnittsomvandlare; Induktor Design; Multiobektiv Optimering;

    Sammanfattning : Hydrogen has been identified by the European Commission to be a competitive alternative to fossil fuels within the transport sector in the medium to long perspective. Because of this, an increased understanding is required of the electrical power train present within such vehicles. LÄS MER

  5. 4. Hybrid Coupler for LMBA Input Match Using an Active Inductor

    Magister-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Karthik Doddanna; [2021]
    Nyckelord :LMBA; gyrator-c; active inductor; hybrid coupler; TSMC 0.18um.;

    Sammanfattning : With the increase in demand for compact and high data rate communication systems, there is a need for high efficiency with modulated signals (PAPR 5-10 dB) for base-station power amplifiers. One of the famous architectures used to achieve this is Doherty architecture. LÄS MER

  7. 5. Student Rocket Experiment B2D2 - Power System

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

    Författare :Albert Jansson; Andreas Lezdins; [2020]
    Nyckelord :Power system; DC DC; Lithium; BLDC; REXUS BEXUS; CubeSat;

    Sammanfattning : The B2D2 student experiment aims to study theEarth magnetic field by releasing a free falling unit (FFU) from asounding rocket. The power system of the FFU needs to supply allsubsystems with sufficient power and energy during the flight. LÄS MER
