1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   University essay from Umeå universitet/Institutionen för fysik

   Author : Franz Wikner; [2024]
   Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

5. 4. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

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

   Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

   Abstract : 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. READ MORE

6. 5. Life Cycle Assessment of typical projects of the distribution power network : Assessment, Improvement & Recommendations

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

   Author : Hugo Serres; [2022]
   Keywords : Life cycle assessment; GHG emissions; power infrastructures; Livscykelanalys; växthusgasutsläpp; energiinfrastrukturer;

   Abstract : The carbon footprint of the power generation is studied for more than 30 years now. In order to curb GHG emissions, politics, industrials and consumers tend to take action to reduce the carbon intensity of the electricity mix, spread electrification and enhance usage efficiency.
