    • A Design Methodology of Multiresonant Controllers for High Performance 400 Hz Ground Power Units 
      Rojas, Félix; Cárdenas, Roberto; Clare, Jon; Díaz, Matías; Pereda, Javier; Kennel, Ralph (Institute of Electrical and Electronics Engineers, 2019)
      In aerospace applications, a ground power unit has to provide balanced and sinusoidal 400 Hz phase-to-neutral voltages to unbalanced and nonlinear single-phase loads. Compensation of high-order harmonics is complex, as the ...
    • 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 simplified Space-Vector modulation algorithm for four-leg NPC converters 
      Rojas, Felix; Cárdenas Dobson, Jesús; Kennel, Ralph; Clare, Jon C.; Díaz, Matías (IEEE Inst Electrical and Electronic Engineering Inc., 2017)
      To interface generation sources and loads to fourwire distribution networks it is important to use power converters and modulation methods, which provide high performance, flexibility, and reliability. To achieve these ...
    • 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 ...
    • Vector control of a modular multilevel matrix converter operating over the full output-frequency range 
      Diaz, Matias; Cardenas, Roberto; Espinoza, Mauricio; Hackl, Christoph M.; Rojas, Felix; Clare, Jon C.; Wheeler, Patrick (Institute of Electrical and Electronics Engineers Inc., 2019)
      © 1982-2012 IEEE. The modular multilevel matrix converter (M 3 C) is an ac-to-ac converter topology suitable for the control of high-power variable-speed drives. The control of this converter is complex, particularly when ...
