1. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.

2. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques
University essay from Uppsala universitet/Fasta tillståndets fysikAbstract : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

3. PLL for 5G mmWave
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

4. Power Supply Rejection (PSR) Enhancement Techniques for Fully Integrated Low-Dropout (LDO) Regulators
University essay from Linköpings universitet/Elektroniska Kretsar och SystemAbstract : In this present world, there is a huge requirement of portable devices for that the analysis of low-dropout or LDO regulators have been on high priority. So, for every respective device, there is a power budget that acts as the main constraint to design an LDO. The LDO design aims to suppress the noise and supply noise-free or low noise output.

5. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System
University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktionAbstract : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. READ MORE
