1. 16. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Johan Humla; Samuel Friman; [2023]
   Keywords : ;

   Abstract : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. READ MORE

3. 17. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   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

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

   University essay from Uppsala universitet/Institutionen för elektroteknik

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

   Abstract : 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. READ MORE

5. 19. Thermal Modeling and Simulationwith High Voltage Solid StateRelays for Battery DisconnectionApplications : The potential of replacing mechanical contactors with semiconductors
