  1. 1. Investigation of current sensing techniques for a high bandwidth application : Focusing on Hall-Current Sensing

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

    Author : Enric Ametller; [2023]
    Keywords : Current sensing; High bandwidth; Inverter; Hall-sensors; Strömavkänning; Hög bandbredd; Inverter; Hall-sensorer;

    Abstract : With the ongoing surge in electrification within the automotive industry, the demand for high-power inverters is steadily on the rise. Furthermore, these inverters are now expected to handle increased power loads while maintaining enhanced efficiency. READ MORE

  3. 2. Exploratory study on Additive Manufacturing in Urban mobility

    University essay from

    Author : Kaustubh Deshmukh; [2023]
    Keywords : ;

    Abstract : This thesis report presents a comprehensive study on the design and development of an Additively manufactured Unit cell for car door panels, aiming to enhance impact resistance and reduce noise transmission to the vehicle cabin. In order to accomplish these goals, the study focuses on combining two novel techniques namely quasi-zero stiffness (QZS) structures and phononic crystals (both scattering and locally resonating type).

  4. 3. Modulation of the optical properties of quantum dots by surface acoustic waves

    University essay from KTH/Tillämpad fysik

    Author : Tanguy Schetelat; [2023]
    Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

    Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

  5. 4. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Eric Schyllert; [2023]
    Keywords : Technology and Engineering;

    Abstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE
