  1. 16. Design of a planar transformer for a series loaded resonant converter

    M1-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Andreas Bodegård; [2020]
    Nyckelord :planar transformer; design; PCB; Altium; series loaded resonant converter; SLRC;

    Sammanfattning : This report presents a project that has been made to present the design of a planar transformer as a part of a series loaded resonant DC/DC converter in a power unit. The design is based on an existing transformer that is not planar and so the characteristics of the transformer is translated into a planar version. LÄS MER

  5. 19. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Erik From; [2020]
    Nyckelord :;

    Sammanfattning : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. LÄS MER

  7. 20. Numerical Calculations of Wireless Power Transfer Coil Parameters

    Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Jonatan Nyström; [2020]
    Nyckelord :WPT; Wireless; Charging; Qi; Inductance; Calculation; Inductive; Coupling; Technology and Engineering;

    Sammanfattning : Wireless Power Transfer (WPT) has become a commercially viable technology. The technology uses the phenomenon of electromagnetic induction between coils to transfer electrical power wirelessly. LÄS MER
