    • 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 ...
    • Solid state transformers: concepts, classification, and control 
      Shamshuddin, Mohammed Azharuddin; Rojas, Félix; Cárdenas Dobson, Jesús; Pereda, Javier; Díaz, Matías; Kennel, Ralph (MDPI, 2020)
      Increase in global energy demand and constraints from fossil fuels have encouraged a growing share of renewable energy resources in the utility grid. Accordingly, an increased penetration of direct current (DC) power sources ...
