Fault detection method for modular multilevel converters based on Luenberger observer

Modular multilevel converter (MMC), which is composed of a large number of submodules (SM) connected in series, is one of the most promising converters in high voltage field. The open-circuit fault and short-circuit fault of the SM's power switch seriously affect the reliability of the MMC, and...
