Senturk, Osman S.; Helle, Lars; Munk-Nielsen, Stig; Rodríguez Cortés, Pedro; Teodorescu, Remus (2009)
Open AccessThree-level (3L) neutral point clamped (NPC), flying capacitor (FC), and H-bridge (HB) voltage source converters (VSCs) as a grid-side full-scale medium voltage (MV) converter are modeled, controlled, and simulated for ...
Miranda, Hernan; Teodorescu, Remus; Rodríguez Cortés, Pedro; Helle, Lars (2009)
Open AccessA model predictive control strategy for a highpower, grid connected 3-level neutral clamped point converter is presented. Power losses constraints set a limit on commutation losses so reduced switching frequency is ...
Power capability investigation based on electrothermal models of press-pack IGBT three-level NPC and ANPC VSCs for multimegawatt wind turbines Senturk, Osman S.; Helle, Lars; Rodríguez Cortés, Pedro; Munk-Nielsen, Stig; Teodorescu, Remus (2012-07)
Restricted access - publisher's policyWind turbine power capability is an essential set of data for both wind turbine manufacturers/operators and transmission system operators since the power capability determines whether a wind turbine is able to fulfill ...
