    • LED lamp modelling for harmonic studies in distribution systems 

      Molina, Julio; Mesas García, Juan José; Mesbahi, Nadhir; Sainz Sapera, Luis (2017-03-09)
      Article
      Accés restringit per decisió de l'autor
      Energy saving policies have boosted the use of light emitting diode (LED) lamps in distribution networks. These lamps are non-linear loads which inject harmonic currents into the distribution system, which has led to a ...

    • Model of discharge lamps with magnetic ballast 

      Molina, Julio; Sainz Sapera, Luis; Mesas García, Juan José; Bergas Jané, Joan Gabriel (2013-02)
      Article
      Accés restringit per política de l'editorial
      Magnetic ballast discharge lamp modeling has been extensively studied because these lamps can be an important source of harmonics. Discharge lamp models usually represent the arc voltage by a square waveform. However, this ...

    • Model of discharge lamps with saturated magnetic ballast and non-square arc voltage 

      Molina, Julio; Sainz Sapera, Luis; Monjo Mur, Lluís (2013-11-01)
      Article
      Accés restringit per política de l'editorial
      Harmonic modeling of high intensity discharge lamps with magnetic ballast has been extensively studied because they are energy-efficient lighting devices commonly used in industrial and public installations, and can be ...

    • Model of electronic ballast compact fluorescent lamps 

      Molina, Julio; Sainz Sapera, Luis (2014-06-01)
      Article
      Accés restringit per política de l'editorial
      The use of compact fluorescent lamps (CFLs) in utility distribution systems is spreading due to energy consumption concerns. This can damage system power quality because CFLs are nonlinear harmonic injecting loads. For ...

    • On the square arc voltage waveform model in magnetic discharge lamp studies 

      Molina, Julio; Sainz Sapera, Luis; Mesas García, Juan José (2011)
