(PDF) Submodule Fault-Tolerant Strategy For Modular Multilevel Converter With Scalable Control ... Fault tolerant control strategy for sub module faults of modular multilevel converters published in: 2019 ieee 12th international symposium on diagnostics for electrical machines, power electronics and drives (sdemped). In this paper, the open circuit fault characteristics of an insulated gate bipolar transistor (igbt) in a sub module are analyzed, and a fault tolerant optimal control strategy is proposed for the redundant hot reserved mmc based on nearest level modulation (nlm). Based on this, a neutral point dc side shift control method is proposed to further improve the fault tolerance capability of the modular multilevel converter (mmc) system by compensating the fault phase voltage with non fault phase voltage. To strengthen the performances of mmcs under submodule (sm) faults, a fault tolerant strategy based on the nearest level modulation (nlm) is proposed in this paper.
