    Nescolarde Selva, Lexa Digna; Yanguas Leyes, Javier; Terricabras, Joaquim; Lukaski, Henry; Alomar, Xavier; Rosell Ferrer, Francisco Javier; Rodas Font, Gil (Institute of Physics (IOP), 2017-07-01)
    Article
    Accés obert
    Sport-related muscle injury classifications are based basically on imaging criteria such as ultrasound (US) and magnetic resonance imaging (MRI) without consensus because of a lack of clinical prognostics for return-to-play ...

  • Influence of data resolution in nonlinear loads model for harmonics prediction 

    Balcells Sendra, Josep; Lamich Arocas, Manuel; Griful Ponsati, Eulàlia; Corbalán Fuertes, Montserrat (2016)
    Article
    Accés obert
    This paper describes the influence of data resolution in the agreement of models to predict harmonics generated by nonlinear loads (NLL), basically formed by single phase and three phase rectifiers, eventually combined ...
  • Variable structure control for three-phase LCL-filtered inverters using a reduced converter model 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Hoz Casas, Jordi de la (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-16)
    Article
    Accés obert
    This paper presents a new concept in active damping techniques using a reduced model of a LCL-filtered grid connected inverter. The presence of the LCL filter complicates the design of the inverter control scheme, particularly ...
  • Variable structure control in natural frame for three-phase grid-connected inverters with LCL filter 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Martín Cañadas, María Elena (2017-07-05)
    Article
    Accés obert
    This paper presents a variable structure control in natural frame for a three-phase voltage source inverter. The proposed control method is based on modifying the converter model in natural reference frame, preserving the ...
  • MOSFET degradation dependence on input signal power in a RF power amplifier 

    Crespo Yepes, Albert; Barajas Ojeda, Enrique; Martin Martínez, Javier; Mateo Peña, Diego; Aragonès Cervera, Xavier; Rodríguez Martínez, Rosana; Nafría Maqueda, Montserrat (2017-06-25)
    Article
    Accés obert
    Aging produced by RF stress is experimentally analyzed on a RF CMOS power amplifier (PA), as a function of the stress power level. The selected circuit topology allows observing individual NMOS and PMOS transistors ...
