In critical industrial applications fault diagnosis and fault tolerance are considered key
features, in order to ensure the required reliability and availability levels. In this context, this …

A simultaneous diagnosis method for power switch open-circuit faults and current sensor
faults of grid-connected three-level neutral point clamped (NPC) inverters is proposed …

To increase the reliability of motor drive system, many fault diagnosis approaches have
been reported with regard to three-phase Pulse Width Modulation Voltage Source Inverter …

To combine the advantages of both model-driven and data-driven methods, this article
proposes a model-data-hybrid-driven method to diagnose open-switch faults in power …

This article considers fault detection in the case of a three-phase three-wire (3P3W) inverter,
when only two current sensors are used to save cost or due to a faulty current sensor. With …

This paper proposes a voltage difference residual-based fault diagnosis approach for three-
level converters in electric traction systems. Compared to the existing open-circuit fault …

Traditional open-switch fault diagnosis methods suffer from poor rapidity or robustness. To
solve this issue, a new differential current observer-based fault diagnosis method is …

Open-phase fault (OPF) and open-switch fault (OSF) are two common electrical faults in the
permanent magnet synchronous machine (PMSM) drives. To locate the faults rapidly and …

With the ever-increasing application of permanent magnet synchronous machine (PMSM)
drives, the requirements for safety and reliability are raised. This article presents a detailed …

This article presents a open-circuit fault diagnosis method for a sensorless vector control
system based on the voltage–current hybrid model flux observer. The error voltage, which is …
