    • Capacitor voltage balancing in a three-level-converter-based energy storage system 

      Burusteta, Sendoa; Pou Félix, Josep; Ceballos Recio, Salvador; Marino, Iker; Anzola, Jose Angel; Agelidis, Vassilios (2013-10-01)
      Article
      Accés restringit per política de l'editorial
      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 ...

    • Energy balancing with wide range of operation in the isolated multi-modular converter 

      Verdugo Retamal, Cristian Andrés; Candela García, José Ignacio; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2020-05-04)
      Article
      Accés obert
      The series-connection of modules in multilevel converters are prone to energy imbalances in the dc capacitor due to the differences between the power absorbed and consumed. In renewable energy applications where the primary ...

    • Fault-tolerance capacity of the multilevel active-clamped topology 

      Nicolás Apruzzese, Joan; Busquets Monge, Sergio; Bordonau Farrerons, José; Alepuz Menéndez, Salvador; Calle Prado, Alejandro (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Thanks to the inherent redundancy to generate the different output voltage levels, the multilevel active clamped (MAC) topology presents an important fault-tolerance ability which makes it interesting for several applications. ...

    • Multilevel two quadrant DC/DC converter for regenerative braking in mobile applications 

      Massot Campos, Miquel; Montesinos Miracle, Daniel; Galceran Arellano, Samuel; Rufer, Alfred (2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper different cascaded and multilevel topologies are compared for regenerative braking systems using supercapacitors (SC). It shows that the multilevel buck derived topology can beneficiate from both reduced ...

    • On the roles and interactions of the MMC internal energy balancing degrees of freedom for three-wire three-phase connections 

      Westerman Spier, Daniel; Prieto Araujo, Eduardo; López Mestre, Joaquim; Mehrjerdi, Hasan; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2022-10-10)
      Article
      Accés obert
      This paper proposes a comprehensive analysis of the Modular Multilevel Converter (MMC) focusing on the different arm applied voltage components, that this paper will refer as degrees of freedom (DOFs), which must be ...

    • Optimization-based reference calculation for Modular Multilevel Converters in balanced and unbalanced network conditions 

      Westerman Spier, Daniel; Prieto-Araujo, E.; López Mestre, Joaquim; Gomis-Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Comunicació de congrés
      Accés obert
      The paper addresses an optimization-based algorithm to calculate the references of the Modular Multilevel Converter (MMC) during normal and constrained scenarios (when the prioritization of quantities is required). The ...
