  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. The temporal side of pull request acceptance

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

    Författare :Balthazar West; [2023]
    Nyckelord :Pull requests; GitHub; code review; machine learning; survey; Pull requests; GitHub; kodrecension; maskininlärning; enkät;

    Sammanfattning : The contemporary way of contributing to open-source software is through online platforms. GitHub is the most widely used platform for this purpose. On GitHub, users can suggest improvements to projects by opening a pull request (PR), taking on the role of the submitter. LÄS MER

  4. 3. Bi-directional Charging System Design for a set of Li-ion Batteries Located at Angstrom Laboratory Campus of Uppsala University

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Mosab Mohammed; [2023]
    Nyckelord :Onboard chargers; bidirectional charging system;

    Sammanfattning : In this study, onboard chargers for EVs are investigated and a design of bi-directional onboard chargers is proposed and simulated. The goal of the charger is to be built in the future to be used in the test setup at Uppsala University. LÄS MER

  5. 4. Energy renovation packages for the decarbonisation of Swedish multifamily buildings

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Bhavik Daya; Hugh Nolan; [2022]
    Nyckelord :Decarbonisation; Renovation; Multi-family homes; Life Cycle Assessment; Life Cycle Costing; Technology and Engineering;

    Sammanfattning : Sweden and Europe aim to be carbon neutral by 2045 and 2050 respectively. Upgrading the existing building stock has been identified as having great potential in assisting to realise these goals. LÄS MER

  7. 5. 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)
