3. 7. 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.
