1. 1. 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

3. 2. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

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

   Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

4. 3. Design and Control of Bidirectional Converters for DC Microgrids

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

   Författare :Gustav Eckerbom; Villiam Petermann; [2023]
   Nyckelord :;

   Sammanfattning : This study aims to summarize the design of two common types of bidirectional DC-DC convertersfound in microgrids, as well as use two distinct control methods for each converter and validate theirperformance. Microgrids are decentralized, small-scale power systems that can operateindependently of the main power grid and are an important solution in order to integrate moreintermittent energy sources, such as solar and wind power, into the energy mix.

   Sammanfattning : With the increase of electric vehicles (EVs) on the roads the availability of charging infrastructure becomes more important. Today it is relatively straightforward to install fast chargers in areas with strong power grid connections, such as in urban areas. LÄS MER

7. 5. A modular switching system as a flexible charging solution for a logistics terminal

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Axel Stenström; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The ambition to move road transport from fossil fuels to electric energy is a large undertaking. One of the biggest challenges with making the trucks fully electric is to charge them. LÄS MER
