Nonsuperconducting Fault Current Limiter With Controlling the Magnitudes of Fault Currents
IEEE Transactions on Power Electronics, 2009In this paper, a diode-bridge-type nonsuperconductor fault current limiter (NSFCL) is proposed. The structure has the capability of controlling the DC reactor current that yields to control the magnitude of fault current. In order to control the magnitude of DC reactor current, a discharging resistor is used in the proposed structure.

CURRENTS in excess of normal, or fault currents, flow in rectifier circuits under conditions of arc-back or d-c short circuit. In normal service, faults are imposed on rectifiers by both the arc-backs that occur in the rectifier itself and the short circuits that occur in the external d-c system.

Employing Fault Currents in the Reliability Analysis of Motor Drives
IEEE transactions on industry applications, 2020This article presents a method to include fault currents in the reliability analysis of motor drives. The presented method is based on formulating a fault current matrix (FCM), the elements of which are values of the currents flowing in all parts of a ...

A comprehensive procedure for the analysis of fault currents in power rectifiers has been developed and some of the more usual cases have been analyzed for the 6-phase double-Y circuit. However, further analyses are still required to cover all the conditions which may be encountered in practice and provide a ready means for determining fault currents.

Adaptive Fault-Tolerant Control for Open-Circuit Faults in Dual Three-Phase PMSM Drives
IEEE transactions on power electronics, 2023The traditional fault-tolerant procedure usually comprises fault detection and fault tolerance. Fault detection is adopted to locate the specific fault, which increases the complexity and misdiagnosis risk of fault-tolerant systems.

Voltage-controlled three-phase three-leg inverters are widely applied in various occasions. The inverters are generally switched to the current-controlled mode to limit the fault currents when short-circuit faults happen.
