    • A comprehensive model for lithium-ion batteries: from the physical principles to an electrical model 

      Berrueta Irigoyen, Alberto Upna; Urtasun Erburu, Andoni Upna; Ursúa Rubio, Alfredo Upna; Sanchis Gúrpide, Pablo Upna (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      The growing interest in e-mobility and the increasing installation of renewable energy-based systems are leading to rapid improvements in lithium-ion batteries. In this context, battery manufacturers and engineers require ...
    • High frequency power transformers with foil windings: maximum interleaving and optimal design 

      Barrios Rípodas, Ernesto Upna; Urtasun Erburu, Andoni Upna; Ursúa Rubio, Alfredo Upna; Marroyo Palomo, Luis Upna; Sanchis Gúrpide, Pablo Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      Foil conductors and primary and secondary interleaving are normally used to minimize winding losses in high frequency transformers used for high-current power applications. However, winding interleaving complicates the ...
    • Modelling of PEM fuel cell performance: steady-state and dynamic experimental validation 

      San Martín Biurrun, Idoia Upna; Ursúa Rubio, Alfredo Upna; Sanchis Gúrpide, Pablo Upna (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      This paper reports on the modelling of a commercial 1.2 kW proton exchange membrane fuel cell (PEMFC), based on interrelated electrical and thermal models. The electrical model proposed is based on the integration of the ...
