    • Reduction of electromagnetic interference susceptibility in small-signal analog circuits using complementary split-ring resonators 

      Pérez Robles, Daniel; Gil Galí, Ignacio; Gago Barrio, Javier; Fernández García, Raúl; Balcells Sendra, Josep; González Díez, David; Berbel Artal, Néstor; Mon González, Juan (IEEE, 2012-02-10)
      Article
      Accés obert
      Low-frequency analog and digital electronic circuits are susceptible to electromagnetic interference in the radiofrequency (RF) range. This disturbance is produced when the coupled RF signal is rectified by the nonlinear ...

    • Reduction of EMI by Combining Interleaving and Modulation Techniques in Multiconverter Topology 

      Mon González, Juan; Gago Barrio, Javier; González Díez, David; Balcells Sendra, Josep; Fernández García, Raúl; Gil Galí, Ignacio (2009)
      Text en actes de congrés
      Accés obert
      In this paper an evaluation of different modulations techniques that combine switching frequency modulation and interleaving is presented. The objective of these modulations is to cancel certain harmonics of EMI and to ...

    • Técnicas de reducción EMI en sistemas multiconvertidor con conexión en paralelo 

      Mon González, Juan; Gago Barrio, Javier; González Díez, David; Balcells Sendra, Josep (Universitat Politècnica de Catalunya. Departament d'Enginyeria Electrònica (EEL), 2009)
      Text en actes de congrés
      Accés obert
      En el presente artículo se analizan diferentes técnicas para la reducción de las EMI generadas por sistemas multiconvertidor con conexión en paralelo. La reducción de las perturbaciones generadas se logra por medio de la ...

    • Validation of EMI model for matrix converters 

      Espina Masramon, Jorge; Balcells Sendra, Josep; Arias Pujol, Antoni; Ortega García, Carlos; González Díez, David; Gago Barrio, Javier (IEEEXPLORE, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper is focused on the validation of a previously presented method to obtain conducted EMI in direct matrix converters (MC). Such model is based on a frequency domain equivalent circuit, which is applied to two ...

    • Wavelet-based approach to evaluation of signal integrity 

      Bialasiewicz, Jan T.; González Díez, David; Balcells Sendra, Josep; Gago Barrio, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2013-10-07)
      Article
      Accés obert
      In this paper, we present a new approach to evaluation of signal integrity that is based on signal energy density as a function of time and frequency, represented by its wavelet scalogram. Using signal integrity ratio and ...
