Development of a Generalized Multilevel SVM and Capacitor Voltage Balancing Strategy for Multiphase Three-Level NPC Converters
This paper proposes a generalized space vector modulation (SVM) strategy for 3-level neutral-point-clamped (NPC) converters.The proposed strategy, here referred to as multiphase 3-level SVM (MP3L-SVM), is developed as a generic modulation technique applicable for 3-level NPC converters with any number of phases, while for showcasing in this paper t
