    • Analyzing the effect of dynamic pressure drop on corona discharges for aircraft applications 

      Bas Calopa, Pau; Riba Ruiz, Jordi-Roger; Moreno Eguilaz, Juan Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2023-03-22)
      Article
      Open Access
      The combination of the low-pressure environment found in aircraft systems and the gradual electrification of aircraft increases the risk of electrical discharges occurrence. This is an undesirable situation that compromises ...
    • Corona discharge characteristics under variable frequency and pressure environments 

      Bas Calopa, Pau; Riba Ruiz, Jordi-Roger; Moreno Eguilaz, Juan Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-08)
      Article
      Open Access
      More electric aircrafts (MEAs) are paving the path to all electric aircrafts (AEAs), which make a much more intensive use of electrical power than conventional aircrafts. Due to the strict weight requirements, both MEA and ...
    • Disseny i càlcul d'un motor síncron d'imants permanents per a un vehicle elèctric 

      Bas Calopa, Pau (Universitat Politècnica de Catalunya, 2020-07-24)
      Master thesis
      Open Access
      El motor elèctric és un dels sistemes més eficients per a convertir energia en moviment i tanmateix és de les màquines més senzilles. Malgrat aquesta aparent senzillesa, al darrere s’hi amaga tot un món de fenòmens ...
    • Experimental validation of the adiabatic assumption of short-circuit tests on bare conductors 

      Riba Ruiz, Jordi-Roger; González Farré, David; Bas Calopa, Pau; Moreno Eguilaz, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2023-05-31)
