title = "Universal Neutral Point Balancing Algorithm for Three-phase Three-level Converters with Hybrid of Zero-sequence Signal Injection and Virtual Zero-level Modulation",
abstract = "This paper presents a new carrier-based voltage balancing scheme for three-phase, three-level converters. The proposed scheme utilizes two available degrees of freedom, Zero-sequence Signal Injection (ZSI) and Virtual Zero-level Modulation (VZM), to eliminate the low-frequency neutral point voltage oscillation. It is universally effective over the full power factor and modulation index range and easy to implement in digital controllers. The main drawback of VZM, increased switching loss due to additional switching transitions, is minimized in this scheme. Extra controllability is gained in the proposed hybrid scheme by utilizing two degrees of freedom at the same time. The performance of proposed scheme is evaluated through simulation models and an experimental test rig.",
