  1. 1. Development of an experimental six-phase induction machine drive

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

    Författare :Adam Bianchi; [2021]
    Nyckelord :Asymmetrical six-phase induction machine; indirect rotor field oriented control; machine rewinding; multiphase electrical machines; PCB design; speed control; the star of the slot .; Asymmetrisk sexfasig asynkronmaskin; flerfasiga elektriska maskiner; hastighetsreglering; indirekt rotorfälts orienterad reglering; kretskorts design; maskinomlindning; the star of the slot .;

    Sammanfattning : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. LÄS MER

  3. 2. Design of current transformer energy harvesting power supply

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Oscar Bäckman; [2021]
    Nyckelord :Energy harvesting; Current transformer;

    Sammanfattning : This thesis explores the possible method to harvest energy from ambient sources around power transformers. These include magnetic induction and vibration. The objective is to create an energy harvester device that can output enough energy to power multiple sensors, wireless connectivity and an MCU. LÄS MER

  4. 3. 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.

  5. 4. Induction in Printed Circuit Boards using Magnetic Near-Field Transmissions

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Simon Arkeholt; [2018]
    Nyckelord :Electromagnetic fields; wave propagation; near-field; VLF range; PCB induction; NFMI system; inductive coupling;

    Sammanfattning : In 1865 Maxwell outlined the theoretical framework for electromagnetic field propagation. Since then many important developments have been made in the field, with an emphasis on systems using high frequencies for long-range interactions. LÄS MER

  7. 5. Uppsala Universitet : Electronic project - heat lock for bikes

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Mauricio Ramirez Zavala; [2018]
    Nyckelord :heat lock; bike heat lock; heating lock; lock heater;

    Sammanfattning : This project explores the idea of implementing an electronic device that can melt away ice from frozen bike locks. It narrates the process of starting with no knowledge of how heating works and ending with a manufactured and soldered PCB with limited heating capability. LÄS MER
