Open‐switch fault diagnosis in three‐level rectifiers based on selective calculation method for instant voltage deviation

Abstract This paper presents an open‐switch fault detection, and identification method for a neutral‐point clamped rectifier system. A new calculation method for phase‐to‐phase pole voltage deviations is proposed for reducing calculation errors. In this way, the more accurate diagnosis can be achiev...
