  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. Antenna as a sensor for sensing available LTE networks

    Author : Barath Kumar Sathish Kumar; [2022]
    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  4. 3. RF Energy Harversting : Design and implementation of an RF energy harvesting system for SoC

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Erlend Sanden; [2019]
    Keywords : Power management; radio frequency harvesting; low power device;

    Abstract : This assignment was given by Nordic Semiconductor. In this project a radio frequency energy harvesting system able to harvest ambient power at 900 MHz (GSM) was simulated and designed. A Villard voltage multiplier, boost converter and power management circuit was implemented for the harvesting system. READ MORE

  5. 4. DLL Based Reference Multiplier for the use in a PLL for WLAN applications

    University essay from Lunds universitet/Fysiska institutionen

    Author : Kamal Gupta; [2015]
    Keywords : reference multiplier; Frequency synthesizer; Frequency multiplier; PLL; DLL; Delay locked loop; VCDL; inverter-based VCDL; charge pump; XOR phase detector; phase noise; 4X multiplier; Technology and Engineering;

    Abstract : This master’s thesis project report deals with the design of multiplier for the reference signal to the Phase Locked Loop (PLL) used in WLAN application. The reference multiplier designed is based on a newly proposed architecture of dual loop feedback Delay Locked Loop (DLL) in which multiplication is performed within the loops. READ MORE

  6. 5. Instabilities in Pulsating Pipe Flow of Shear-Thinning and Shear-Thickening Fluids

    University essay from Mekanisk värmeteori och strömningslära; Tekniska högskolan

    Author : Sasan Sadrizadeh; [2012]
    Keywords : Stability; Pulsatile pipe; Transient Growth; Floquet Multiplier; Modal and non-Modal Stability;

    Abstract : In this study, we have considered the modal and non-modal stability of fluids with shear-dependent viscosity flowing in a rigid straight pipe. A second order finite-difference code is used for the simulation of pipe flow in the cylindrical coordinate system. The Carreau-Yasuda model where the rheological parameters vary in the range of 0.
