      This paper proposes multi-level PV system; three PV generators each coupled to a buck cell. Each PV-generator-buckconverter channel is controlled such that maximum power is captured independently under different irradiation ...
    • Autonomous photovoltaic lighting system 

      Hafez, Ahmed A. A.; Montesinos Miracle, Daniel; Sudrià Andreu, Antoni (2012)
      Article
      Open Access
      This paper introduces a comparison between the conventional and Photovoltaic (PV) lighting systems. A simple sizing procedure for a PV stand-alone system was advised. The paper also proposes a novel PV lighting system. The ...
    • Simple maximum power point controller for single-phase grid-connected PV system 

      Hafez, Ahmed A. A.; Montesinos Miracle, Daniel; Sudrià Andreu, Antoni (2010)
      Conference report
      Open Access
      This paper proposes a simple and efficient PI controller for single-phase grid-connected PV generator. The controller ensures the system operation at maximum power point (MPP) irrespective to atmospheric conditions. A ...
