• Modular multilevel DC-DC converter with arm interchange concept 

      Elserougi, A.; Abdelsalam, I.; Massoud, Ahmed; Ahmed, S. ( Institution of Engineering and Technology , 2020 , Article)
      Conventional modular multilevel converters (MMCs) are promising converters for high-voltage high-power applications. Unlike DC-AC conversion, DC-DC conversion of MMCs suffers from unbalanced capacitor voltages due to the ...
    • Multiple-module high-gain high-voltage DCDC transformers for offshore wind energy systems 

      Denniston, N.; Massoud, Ahmed; Ahmed, S.; Enjeti, P.N. ( IEEE , 2011 , Article)
      Renewable energy sources, such as offshore wind farms, require high voltage gains in order to interface with power transmission networks. These conversions are normally made using bulky, complex, and costly transformers ...
