    • 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 ...
    • An overview of four-leg converters: topologies, modulations, control and applications 
      Rojas, Félix; Cárdenas Dobson, Jesús Roberto; Burgos Mellado, Claudio; Espina, Enrique; Pineda, Cristian; Díaz, Matías (IEEE, 2022)
      In three-phase unbalanced systems, where the circulation of zero sequence current is necessary, four-leg converters provide a neutral connection for single-phase or other unbalanced loads typically utilized in three-phase ...
    • Cooperative regulation of imbalances in three-phase four-wire microgrids using single-phase droop control ... 
      Espina González, Enrique; Cárdenas Dobson, Roberto; Espinoza-B, Mauricio; Burgos Mellado, Claudio; Sáez Hueichapan, Doris (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Collaborative control of power converters operating in microgrids with unbalanced single-phase loads is difficult to achieve, considering that the voltages and currents have positive-, negative-, and zero-sequence components. ...
