      Schaefer, Markus (Universitat Politècnica de Catalunya, 2017-11-08)
      Doctoral thesis
      Open Access
      Control schemes for inverters of different topologies and various numbers of voltage levels are of great interest for many standard as well as special applications. This thesis describes a novel, robust and high-dynamic ...
    • Direct current control for grid-connected diode-clamped inverters 

      Schaefer, Markus; Goetze, Wolf; Hofmann, Martin; Bayer, Fabian; Montesinos Miracle, Daniel; Ackva, Ansgar (Institute of Electrical and Electronics Engineers (IEEE), 2017-04-01)
      Article
      Open Access
      The accurate control of the line current, robust and dynamic behavior even under distorted grids and other system faults are the most important requirements for grid-connected inverters. Applying direct current control to ...
