      Text en actes de congrés
      Accés obert
      The main drawback of Shunt Hybrid Filters is the need of leading current injection. This paper describes a strategy to reduce the leading current in a three phase four wires LC coupled parallel hybrid filter for harmonics ...

    • Current-balancing technique for interleaved voltage source inverters with magnetically coupled legs connected in parallel 

      Capellá Frau, Gabriel José; Pou Félix, Josep; Ceballos Recio, Salvador; Zaragoza Bertomeu, Jordi; Agelidis, Vassilios (Institute of Electrical and Electronics Engineers (IEEE), 2015-03-01)
      Article
      Accés obert
      Connecting legs in parallel in a voltage source inverter is a way to increase the output current and, thus, its rated power. The connection can be made using either coupled or uncoupled inductors, and achieving an even ...

    • 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
      Accés obert
      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 ...

    • Estudio comparativo entre el control en el marco de referencia αβ y el control predictivo basado en el modelo dinámico del sistema para un filtro activo en paralelo 

      Gaitán Rodríguez, Diana Milena (Universitat Politècnica de Catalunya, 2019-01-31)
      Projecte Final de Màster Oficial
      Accés obert
      [CASTELLÀ] El uso de elementos electrónicos en las aplicaciones industriales está en constante crecimiento debido a las ventajas que éstos presentan en términos del control del comportamiento de sistemas. Dicho esto, el ...

    • Model-based control for a three-phase shunt active power filter 

      Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Morales López, Javier; Castilla Fernández, Miguel; Miret Tomàs, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2016-03-10)
      Article
      Accés obert
      This paper presents a robust model-based control in natural frame for a three-phase shunt active power filter. For the proposed control method a linear converter model is deduced. Then, this model is used in a Kalman ...

    • Passivity-based analysis and performance enhancement of a vector controlled VSC connected to a weak AC Grid
