   Sammanfattning : The battery energy storage system (BESS) is crucial for the energy transition and decarbonisation of the energy sector. However, reliability assessment and capital cost challenges can hinder their widespread deployment. LÄS MER

3. 2. Phase Noise Performance of a PLL Frequency Synthesizer when Powered by Silent Switchers

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Sampriti Basu; [2023]
   Nyckelord :Silent Switcher; PLL synthesizer; Phase noise; PCB implementation.; Silent Switcher; PLL-synthesizer; fasbrus; PCB-implementering.;

   Sammanfattning : In use today are ‘normal’ DC-DC switching regulators with considerable switching noise and ringing, which is bad for noise-sensitive applications. This project involves a solution based on ‘Silent Switchers’ to prove its effectiveness in reducing noise. LÄS MER

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

   Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Nyckelord :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;

   Sammanfattning : 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

7. 5. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

   Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Kaj Törngren Sato; [2023]
   Nyckelord :Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

   Sammanfattning : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. LÄS MER
