    This study presents the analysis and design of a sliding-mode control of a buck converter operating in continuous conduction mode that minimises the energy during start-up and provides output voltage regulation in front ...
  • Control digital basado en AFC de un rectificador trifásico PWM 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (2013)
    Text en actes de congrés
    Accés obert
    La operación de los convertidores de potencia conectados a la red eléctrica está sometida cada vez a más condicionantes (reducción de armónicos, funcionamiento en presencia de sags y swells, altas impedancias de red, etc.). ...
  • Design of discrete-time finite-gain resonators in AFC control 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The control technique based on infinite-gain resonators also called Adaptive Feedforward Cancellation (AFC) has been used for some years, mainly in continuous time. In this article, finite-gain resonators in discrete time ...
  • Digital AFC control of a three-phase three-wire unity-power-factor PWM rectifier 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (IEEE, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Nowadays, ac/dc power converters must fulfill more and more design constraints with respect to the electrical grid: harmonics reduction, operation with sags and swells and/or high grid impedances, etc. This is a challenge ...
  • Discrete-time AFC control of a single-phase full-bridge LCL PWM rectifier 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Controllers for ac/dc power converters are subject to many constraints: first, they must be reliable when working conditions are not ideal, i.e., when the grid voltages present sags or swells, big impedances, changes in ...
  • On the stability of discrete-time active damping methods for VSI converters with a LCL input filter 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (2012)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The use of LCL filters with VSI converters is interesting since they present good attenuation of current ripple at high frequencies. Nevertheless, they also present a high resonance peak which can cause undesired oscillations, ...
  • Power flow limitations for LCL grid-connected power converters 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (2014)
    Text en actes de congrés
    Accés obert
    The controllers of VSI Power Converters connected to the electrical grid can produce line currents in phase (or not) with respect to the phase-to-neutral voltages. The amplitude of the currents and the phase difference are ...
  • Some considerations about discrete-time AFC controllers 

    Orellana Barceló, Marcos; Griñó Cubero, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2013)
