    This paper discusses a grid-connected energy storage system based on two three-level (3L) converters: a DC-DC one and a neutral-point-clamped inverter. When compared to a system using standard two-level converters, the ...
  • Circulating current injection methods based on instantaneous information for the modular multilevel converter 

    Pou Félix, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Agelidis, Vassilios; Picas Prat, Ricard; Zaragoza Bertomeu, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2015-02-01)
    Article
    Open Access
    This paper studies different circulating current references for the modular multilevel converter. The circulating current references are obtained from the instantaneous values of the output current and modulation signal ...
  • Current-balancing technique for interleaved voltage source inverters with magnetically coupled legs connected in parallel 

    Capellá Frau, Gabriel José; Pou Félix, Josep; Ceballos Recio, Salvador; Zaragoza Bertomeu, Jordi; Agelidis, Vassilios (Institute of Electrical and Electronics Engineers (IEEE), 2015-03-01)
    Article
    Open Access
    Connecting legs in parallel in a voltage source inverter is a way to increase the output current and, thus, its rated power. The connection can be made using either coupled or uncoupled inductors, and achieving an even ...
  • Enhanced phase-shifted PWM carrier disposition for interleaved voltage-source inverters 

    Capellá Frau, Gabriel José; Pou Félix, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Zaragoza Bertomeu, Jordi; Agelidis, Vassilios (2014-03-01)
    Article
    Open Access
    This letter presents a novel implementation of pulse width modulation that improves the quality of the line-to-line output voltages in interleaved multiphase voltage-source inverters (VSIs). In multiphase VSIs with n ...
