Fault-Tolerant Control Strategies and Capability without Redundant Sub-Modules in Modular Multilevel Converters
Sub-module (SM) faults in modular multilevel converters (MMCs) without redundancies result in unbalanced converter output voltages and improper control of modulation due to an unequal number of SMs inserted between the different phase-legs. The derived mathematics model of the MMC demonstrates the i...
