1. 41. Control, Modulation and Implementation of Modular Multilevel Converters

   Författare :Antonios Antonopoulos; Hans-Peter Nee; Colin Oates; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular Multilevel Converter; Modulation; Feedback Control; Open-Loop Control; Implementation; Prototype; High-Performance Motor Drives; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : 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. LÄS MER

7. 45. Critical Factors for digital Printing on Paperboard : Runnability, Functionality & Print Quality

   Författare :Veronica Gidlöf; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital printing; paperboard; electrophotography; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

   Sammanfattning : More than ten years ago, the first digital print units were introduced on the market and since then, the technology has developed rapidly. Digital printing on packaging material is, however, a rather new area, but a probable prediction is that there soon will be a market need for board products that can be used for digital printing.
