    • A New Space-Vector-Modulation Algorithm for a Three-Level Four-Leg NPC Inverter 
      Rojas, Félix; Kennel, Ralph; Cárdenas Dobson, Jesús Roberto; Repenning, Ricardo; Clare, Jon C.; Díaz, Matías (IEEE, 2017)
      For power conversion systems interfaced to four-wire supplies, four-leg converters have become a standard solution. A four-leg converter allows good compensation of zero-sequence harmonics and full utilisation of the dc-link ...
    • A novel Capacitor Voltage Balancing strategy for Modular Multilevel Converters 
      Urrutia, Matías; Mora, Andrés; Angulo, Alejandro; Lezana, Pablo; Cárdenas Dobson, Roberto; Díaz, Matías (IEEE, 2018)
      This paper presents a simple and innovative Capacitor Voltage Balancing (CVB) strategy for Modular Multilevel Converters (MMC) based on full H-bridge cell topologies. The method computes specific modulation indexes for ...
    • An integrated converter and machine control system for MMC-based high-power drives 
      Espinoza-B, Mauricio; Cárdenas Dobson, Jesús Roberto; Clare, Jon; Soto Sánchez, Diego; Díaz, Matías; Espina, Enrique; Hackl, Christoph M. (IEEE, 2019)
      The modular multilevel converter (MMC) is a promising topology for high-power drive applications. However, large voltage fluctuations can be produced in the floating capacitors when the machine operates with high stator ...
    • An overview of applications of the modular multilevel matrix converter 
      Diaz, Matías; Cárdenas Dobson, Roberto; Ibaceta, Efraín; Mora, Andrés; Urrutia, Matías; Espinoza, Mauricio; Rojas, Félix; Wheeler, Patrick (MDPI, 2020)
      The modular multilevel matrix converter is a relatively new power converter topology suitable for high-power alternating current (AC)-to-AC applications. Several publications in the literature have highlighted the converter ...
    • Model-predictive-control-based capacitor voltage balancing strategies for modular multilevel converters 
      Mora, Andrés; Urrutia, Matías; Cárdenas Dobson, Jesús Roberto; Angulo, Alejandro; Cerda Espinoza, Mauricio Alexis; Díaz, Matías; Lezana, Pablo (IEEE, 2019)
      This paper presents two capacitor voltage balancing (CVB) strategies for modular multilevel converter (MMC) applications. Both balancing schemes are based on model predictive control and are designed to efficiently solve ...
    • Modular Multilevel Converter Based Topology for High-Speed, Low-Voltage Electric Drives 
      Tarisciotti, Luca; Costabeber, Alessandro; Tardelli, Francesco; Cárdenas Dobson, Jesús Roberto (IEEE-Inst. Electrical Electronics Engineers, 2020)
      The increasing demand for higher power density and more efficient electric drives, in particular, from the automotive industry, has pushed engineers investigating new solutions. Recently, wide bandgap devices have been ...
