3. Control, Modulation and Implementation of Modular Multilevel Converters
Abstract : Denna avhandling behandlar analys och styrning av den modulära multinivå omvandlaren (M2C). M2C är en lovande omvandlarteknologi för högspända högeffekttillämpningar. Anledningen till detta är låg distorsion i utstorheterna kan uppnås med låg medelswitchfrekvens per switch och utan utgångsfilter. READ MORE
