      The Permanent Magnet Synchronous Generator (PMSG) with diode bridge is frequently used in small Wind Energy Conversion Systems (WECS). This configuration is robust and cheap, and therefore suitable for small WECS. In order ...
    • 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 ...
