1. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : 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. LÄS MER
2. Antenna as a sensor for sensing available LTE networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. RF Energy Harversting : Design and implementation of an RF energy harvesting system for SoC
Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : 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. LÄS MER
4. Developing a test procedure for neutron detection/non detection using a Small TPC Prototype
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : This work relates to the proposed n-nbar experiment at ESS and covers a procedure with which future neutron research can be made using a small TPC prototype. Settings for the GEM amplification voltage supply and main drift field across the chamber have been established using minimum ionizing cosmic muons as a reference. LÄS MER
5. DLL Based Reference Multiplier for the use in a PLL for WLAN applications
Master-uppsats, Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
