  1. 1. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

  3. 2. 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

  4. 3. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Hiruy Michael Weldegiorgish; [2022]
    Keywords : Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

    Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

    Abstract : Superconducting nanowire single-photon detectors are the most promising technology in quantum photon information. They offer high speed, high detection efficiency, low dark count rate as well as low timing jitter compared to other single photon detection solutions. READ MORE

  6. 5. Current measurements of low-power battery driven devices

    University essay from Uppsala universitet/Signaler och system

    Author : Marcus Wahlberg; [2022]
    Keywords : Current meter; current measurement; shunt resistor; auto-range; current-range;

    Abstract : A current meter has been designed, intended for surveillance of low-power battery driven devices with a large dynamic range in their current consumption. Among such devices may, for example, be nodes in a wireless sensor network (WSN). READ MORE
