  1. 21. Investigation into the pedagogical value of demonstrating deliberate design deficiencies in PCB design instruction

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

    Författare :Björn Sunedal; [2021]
    Nyckelord :PCB design; Interactive Lecture Demonstration; PODS; pedagogy; PCB-konstruktion; Interaktiv föreläsningsdemonstration; PODS; pedagogik;

    Sammanfattning : Universities and other higher education institutions have been struggling with high levels of student dropouts and poor graduation rates for a long time. As a result, there has been an interest in modifying traditional teaching techniques and implementing new ones to improve student learning outcomes. LÄS MER

  3. 22. DC-DC capacitor precharger

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

    Författare :Hannes Bydén; Alexander Lundström; [2020]
    Nyckelord :capacitor charger flyback converter; Technology and Engineering;

    Sammanfattning : This study evaluates the possibility of charging large capacitors to high voltages within short time frames. The system is designed to charge a capacitor of 4 mF from 0 to 850 V in one second by connecting a 24 V lead acid car battery to a flyback converter. LÄS MER

  4. 23. 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. 24. MOSFET Packaging for Low Voltage DC/DC Converter : Comparing embedded PCB packaging to newly developed packaging

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Emil Dahl; [2020]
    Nyckelord :embedded components; embedded MOSFETs; MOSFET packaging; power module;

    Sammanfattning : This thesis studies the options of using PCB embedding bare die power MOSFET and new packaging of MOSFET to increase the power density in a PCB. This is to decrease the winding losses in an isolated DC/DC converter which, according to "Flex Power Modules", can be done by improving the interleaving between the layers of the transformer and/or decreasing the AC loop.

  7. 25. QUIC Behavior over Dual Connectivity : Understanding QUIC throughput and fairness

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :David Hasselquist; Christoffer Lindström; [2020]
    Nyckelord :QUIC; Dual Connectivity; Throughput; Fairness;

    Sammanfattning : QUIC is a relatively new transport layer network protocol that has gained popularity over the last few years. The protocol was initially developed by Google and standardization work has been continued by the Internet Engineering Task Force (IETF) with the goal of it becoming the next generation transport protocol.
