5. 19. 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

7. 20. EV charging approaches in remote regions – Analysis of capacity, cost and logistics

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Farhaan Ahamed; Juan Ordonez Marin; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. LÄS MER
