1. 6. Model Development for Wave Energy Converter Arrays in the Frequency Domain

   University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Institutionen för fysik och astronomi

   Author : Linn Fredriksson; [2023]
   Keywords : Physics; Energy Physics; Energy; Renewable Energy; Wave Power; CorPower Ocean; Point Absorber; Array Modelling; Farm modelling; Fysik; Energifysik; Energi; Vågkraft; Förnyelsebar Energi;

   Abstract : In this thesis, a model has been developed to analyze the behavior of wave energy converter arrays in the frequency domain. This development serves the purpose of establishing an in-house model tool for array modelling for CorPower Ocean. READ MORE

3. 7. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Viktor Lewin; [2023]
   Keywords : Phase-locked loop; PLL; DPLL; Frequency Synthesis; TDC; PFD; Technology and Engineering;

   Abstract : This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. READ MORE

4. 8. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs

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

   Author : Elochukwu Mbah; [2023]
   Keywords : Silicon Carbide Power MOSFET; Gate Inductance; Gate Resistance; Miller Period; dv dt and di dt transients; Double Pulse Test; Kiselkarbid Power MOSFET; Gateinduktans; Gate Resistance; Millerperioden; dv dt och di dt transienter; Dubbelpulstest.;

   Abstract : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. READ MORE

5. 9. Study Of Universal Islanding Detection Techniques In Distributed Generation Systems

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Ochai Ochalla Danladi; [2023]
   Keywords : Distributed Generation; Islanding; Quality Factor; Resonance Frequency; Low Voltage; Medium Voltage; Electronic Power Converter; Inverter;

   Abstract : Energy security, global warming, and climate change have been a major source of global discussions and development. Likewise, the rising cost of electricity for consumers and exponential demand for energy are major factors driving the incremental growth and integration of sustainable forms of energy generation into power the system cycle.

6. 10. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

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

   Author : Simon Richter; [2023]
   Keywords : Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

   Abstract : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.
