      Conference report
      Open Access
      This paper presents a comprehensive analysis of SVPWM for a five-phase VSI based on SiC devices applied to motor drives. The modulation techniques analyzed use medium and large vectors to reach the reference vector. The ...

    • Study of modulation techniques applied to full bridge single-phase inverters based on wide-bandgap semiconductors 

      Ferrer Arnau, Luis Jorge; Berbel Artal, Néstor; Capellá Frau, Gabriel José; Zaragoza Bertomeu, Jordi (2019)
      Conference lecture
      Open Access
      Wide-band gap (WBG) devices are gradually replacing standard Si semiconductors in power converters. This is due to the fact that WBG devices exhibit lower capacitance and on-resistance and besides, as they can switch at ...

    • Efficiency analysis of wide band-gap semiconductors for two-level and three-level power converters 

      Lumbreras Carrasco, David; Zaragoza Bertomeu, Jordi; Mon González, Juan; Gálvez, Eduardo; Collado Escolano, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      Power devices based on wide band-gap materials are emerging as alternatives to silicon-based devices. These new devices allow designing and building converters with fewer power losses, and are thus more highly efficient ...

    • Study and comparison of discontinuous modulation for modular multilevel converters in motor drive applications 

      Picas Prat, Ricard; Zaragoza Bertomeu, Jordi; Pou Félix, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Capellá Frau, Gabriel José (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
      Article
      Open Access
      Discontinuous modulation applied to modular multilevel converters is an effective method for reducing the capacitor voltage ripples. In this paper, the discontinuous modulation is adapted and used in a motor drive application. ...

    • Single-carrier phase-disposition PWM techniques for multiple interleaved voltage-source converter legs 

      Konstantinou, Georgios; Capellá Frau, Gabriel José; Pou, Josep; Ceballos Recio, Salvador (Institute of Electrical and Electronics Engineers (IEEE), 2017-10-26)
      Article
      Open Access
      Interleaved converter legs are typically modulated with individual carriers per leg and phase-shifted PWM (PS-PWM) as it facilitates current balancing amongst the legs. Phase-disposition PWM (PD-PWM), despite the better ...

    • Nonlinear loads model for harmonics flow prediction, using multivariate regression 

      Lamich Arocas, Manuel; Balcells Sendra, Josep; Corbalán Fuertes, Montserrat; Griful Ponsati, Eulàlia (Institute of Electrical and Electronics Engineers (IEEE), 2017-06)
      Article
      Open Access
      This paper describes a method for obtaining a model of a single or a set of nonlinear loads (NLL) connected to a certain point of an electrical network. The basic assumption is that the network supplying the NLL has ...
