    • 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 ...
    • A vector control strategy to eliminate active power oscillations in four-leg grid-connected converters under ... 
      Mora, Andrés; Cárdenas Dobson, Jesús; Urrutia, Matías; Rettig Espinoza, Mauricio Alfredo; Díaz, Matías (IEEE, 2020)
      The problems associated with active power oscillations (APOs) in grid-connected converters are well-known. Imbalances in the grid usually produce double-frequency oscillations in the dc-link voltage and current which could ...
    • 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 ...
    • An Overview of Modelling Techniques and Control Strategies for Modular Multilevel Matrix Converters 
      Díaz, Matías; Cárdenas, Roberto; Ibaceta, Efraín; Mora, Andrés; Urrutia, Matías; Rettig Espinoza, Mauricio Alfredo; Rojas, Félix; Wheeler, Patrick (MDPI, 2020)
      The Modular Multilevel Matrix Converter is a relatively new power converter topology appropriate for high-power Alternating Current (AC) to AC purposes. Several publications in the literature have highlighted the converter ...
    • Control of wind energy conversion systems based on the modular multilevel matrix converter 
      Díaz, Matías; Cárdenas Dobson, Jesús; Espinoza, Mauricio; Rojas, Felix; Mora, Andrés; Clare, Jon C.; Wheeler, Pat (IEEE Institute of Electrical and Electronics Engineers, 2017)
      The nominal power of single wind energy conversion systems (WECS) has been steadily increasing, now reaching power ratings close to 10 MW. In the power conversion stage, medium-voltage power converters are replacing the ...
    • Finite-set model-predictive control strategies for a 3L-NPC inverter operating with fixed switching frequency 
      Donoso, Felipe; Mora, Andrés; Cárdenas Dobson, Jesús; Angulo, Alejandro; Sáez Hueichapán, Doris; Rivera, Marco (IEEE Institute of Electrical and Electronics Engineers, 2018)
      In this paper, finite-set model-predictive control (FS-MPC) methodologies for a grid-connected three-level neutral-point-clamped converter are investigated. The proposed control strategies produce fixed switching frequency, ...
    • Late cretaceous to cenozoic deformation and exhumation of the chilean frontal cordillera (28°–29°S), Central Andes 
      Martínez, Fernando; Parra, Mauricio; Arriagada Ortega, César; Mora, Andrés; Bascuñan, Sebastián; Peña, Matías (Elsevier, 2017)
      The Frontal Cordillera in northern Chile is located over the flat-slab subduction segment of the Central Andes. This tectonic province is characterized by a thick-skinned structural style showing evidence of tectonic ...
    • Model Predictive Torque Control for Torque Ripple Compensation in Variable-Speed PMSMs 
      Mora, Andrés; Orellana, Álvaro; Juliet, Jorge; Cárdenas Dobson, Jesús (IEEE-Inst Electrical Electronics Engineers, 2016)
      This paper presents a new and simple finite-control set model predictive control strategy to reduce the torque ripple in permanent-magnet synchronous machines (PMSMs). The method is based on minimizing a cost function that ...
