Fault-Tolerant Operation of an Open-End Winding Five-Phase PMSM Drive with Inverter Faults [PDF]

, 2013
The authors would like to thank the ADEME for the funding of the MHYGALE project.Multi-phase machines are known for their fault-tolerant capability. However, star-connected machines have no fault tolerance to inverter switch short-circuit fault.

A Combined Method for Line Selection of Single Phase to Ground Fault in Compensated Distributions Based on Evidence Theory

IEEE Access, 2023
In order to improve reliability of distributions, the neutrals are usually insulated or compensated with Peterson coil. Thus, the currents of single-phase to ground fault are weak, leading to difficulty in fault line selection problem.
