  1. 1. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  2. 2. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Johansson; [2022]
    Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

  3. 3. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  4. 4. The adolescent brain on social-media : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Michaela Åström; [2021]
    Keywords : Adolescence; neuroimaging; social brain; social rewards; social-media use SMU ;

    Abstract : Adolescence is an exceptional period of life, not least in terms of social and brain development. Friends become increasingly important, susceptibility to peer rejection increases, and brain regions involved in social cognition are predicted to go through major changes. READ MORE

  5. 5. Optimal torque split strategy for BEV powertrain considering thermal effects

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhananjay Yadav; [2021]
    Keywords : Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

    Abstract : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. READ MORE
