      Multi-modular converters have proven to be one of the most suitable topology to be used in high and power applications. The modularity of these configurations offer several advantages, such as: high quality voltage, ...

    • Multilevel-clamped multilevel converters (MLC2) 

      Rodríguez Cortés, Pedro; Bellar, Maria Dias; Muñoz Aguilar, Raúl Santiago; Busquets Monge, Sergio; Blaabjerg, Frede (2012-03)
      Article
      Accés restringit per política de l'editorial
      This letter introduces a new series of multilevel (ML) converters based on the ML clamping concept. By applying this technique, a ML clamping unit (MCU) conveys additional levels for synthesizing the output waveforms ...

    • On addressing the security and stability issues due to false data injection attacks in DC microgrids an adaptive observer approach 

      Cecilia Piñol, Andreu; Sahoo, Subham; Dragicevic, Tomislav; Costa Castelló, Ramon; Blaabjerg, Frede (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Article
      Accés obert
      This paper proposes an observer-based methodology to detect and mitigate false data injection attacks in collaborative DC microgrids. The ability of observers to effectively detect such attacks is complicated by the presence ...

    • On power control of grid-forming converters: modeling, controllability, and full-state feedback design 

      Chen, Meng; Zhou, Dao; Tayyebi, Ali; Prieto Araujo, Eduardo; Dörfler, Florian; Blaabjerg, Frede (Institute of Electrical and Electronics Engineers (IEEE), 2024-01-01)
      Article
      Accés obert
      The popular single-input single-output control structures and classic design methods (e.g., root locus analysis) for the power control of grid-forming converters have limitations in applying to different line characteristics ...

    • Robust admittance shaping approach to grid current harmonic attenuation and resonance damping 

      Cóbreces Álvarez, Santiago; Wang, Xiongfei; Pérez Serrano, Jorge; Griñó Cubero, Robert; Blaabjerg, Frede (2018-09-01)
      Article
      Accés obert
      This paper presents a novel grid current control of a grid-connected voltage source converter with an LCL filter. The proposed control method uses an H 8 synthesis method to shape the input admittance of the converter, to ...
