      Phase-locked loop schemes are widely used in induction heating applications for controlling the converters. Most authors use total or partial analog solutions to implement the control schemes, which are less sturdy and ...

    • Design, management and comissioning of a utility connected microgrid based on IEC 61850 

      Ruiz Alvarez, A.; Colet Subirachs, A.; Gomis Bellmunt, Oriol; Fernández Mola, José María; Alvarez Cuevas, F.; López Mestre, Joaquim; Sudrià Andreu, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Conference lecture
      Open Access
      This paper presents an approach to microgrid automation. The microgrid is composed of three different nodes connected to the public electric grid, which are hardware emulated with back-to-back converters. The microgrid ...

    • Improved current reference calculation for MMCs internal energy balancing control 

      Westerman Spier, Daniel; Prieto-Araujo, E.; López Mestre, Joaquim; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2021-06-22)
      Article
      Open Access
      The paper addresses an improved inner current reference calculation to be employed in the control of modular multilevel converters operating during either balanced or unbalanced conditions. The suggested reference calculation ...

    • Multichannel high-power high-frequency converters for induction heating 

      Martín Segura, Guillermo; Sala Pérez, Pau; Montesinos Miracle, Daniel; Ferrater Simón, María Misericordia; López Mestre, Joaquim (2013)
      Conference lecture
      Restricted access - publisher's policy
      This paper studies a converter structure based on the connection of basic topologies to form a multichannel converter for induction heating applications. The aim of using basic topologies is to provide a reduction of ...

    • 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
      Open Access
      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 ...

    • Optimal current reference calculation for MMCs considering converter limitations 

      Westerman Spier, Daniel; Prieto-Araujo, E.; López Mestre, Joaquim; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2020-08-31)
      Article
      Open Access
      The paper addresses an optimization-based reference calculation method for Modular Multilevel Converters (MMC) operating in normal and constrained situations (when the converter needs to prioritize its quantities as it has ...
