1. 1. 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
