A carrier-based PWM strategy with zero-sequence voltage injection for a three-level neutral-point-clamped converter Pou Félix, Josep; Zaragoza Bertomeu, Jordi; Ceballos Recio, Salvador; Saeedifard, Maryam; Boroyevich, Dushan (Institute of Electrical and Electronics Engineers (IEEE), 2012-01-09)
Restricted access - publisher's policyPerformance of a carrier-based pulsewidth modulation (CB-PWM) strategy can be improved by the inclusion of a zero-sequence voltage in the modulation-reference signal. This paper proposes a new CB-PWM strategy for a three-level ...
Analysis of voltage balancing limits in modular multilevel converters Ceballos Recio, Salvador; Pou Félix, Josep; Choi, Sanghun; Saeedifard, Maryam; Agelidis, Vassilios (IEEE, 2011)
Open AccessThe modular multilevel converter (MMC) is one of the most promising converter topologies for high-voltage applications, especially for high-voltage direct-current (HVDC) transmission systems. One of the most challenging ...
Minimization of the capacitor voltage fluctuations of a modular multilevel converter by circulating current control Picas Prat, Ricard; Pou Félix, Josep; Ceballos Recio, Salvador; Agelidis, Vassilios; Saeedifard, Maryam (2012)
Open AccessThe modular multilevel converter (MMC) is one of the most potential converter topologies for medium/high power/voltage applications. One of the main technical challenges of an MMC is to eliminate/minimize the circulating ...
Steady-state and dynamic performance of front-end diode rectifier loads as predicted by dynamic average-value models Chiniforoosh, Sina; Atighechi, Hamid; Jatskevich, Juri; Davoudi, Ali; Martínez Velasco, Juan Antonio; Saeedifard, Maryam; Aliprantis, D. C.; Sood, V.K. (2013-07)
Restricted access - publisher's policyThe detailed switch-level models of front-end diode recti fi er loads can be readily implemented using a number of transient simulation programs, such as PSCAD/EMTDC, and the toolboxes in Matlab/Simulink. To improve ...
