      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work presents a switching converter topology which can boost and step down the supply voltage and can deliver both positive and negative voltages to a grounded load (bipolar converter topology with non-floating output). ...

    • Autonomous cascaded PV system 

      Hafez, Ahmed A. A.; Montesinos Miracle, Daniel; Sudrià Andreu, Antoni (2011-11-14)
      Article
      Accés restringit per política de l'editorial
      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 ...
