Short-Circuit Fault Detection Observer Design in a PMSM
IEEE Transactions on Aerospace and Electronic Systems, 2018This paper explores detecting interturn short-circuit (ITSC) faults in surface permanent magnet synchronous machines (SPMSM) while simultaneously estimating the (typically large) fault current to determine if operation is within thermal limits. ITSC faults are caused by electrical insulation failures in the stator windings and can lead to shorts to ...

A novel fault detection circuit for short-circuit faults of IGBT
2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011This paper proposed a novel fault detection circuit comparing the gate voltage of IGBT. The proposed scheme is operated to protect IGBT under short-circuit faults such as hard switch-fault (HSF). The proposed circuit consists of two parts. One is the difference generator which generates a difference between a gate voltage and an input voltage.

A Comprehensive Analysis of Short-Circuit Current Behavior in PMSM Interturn Short-Circuit Faults
IEEE Transactions on Power Electronics, 2018This paper presents a detailed analysis of short-circuit current behavior during interturn short-circuit faults in permanent magnet synchronous machines (PMSMs) by considering the short-circuit contact resistance. For this purpose, an finite element analysis (FEA)-based equivalent circuit model is developed to understand the circulating current ...

A Comprehensive Analysis of Short-Circuit Fault in Wound-Rotor Resolvers
IEEE Transactions on Vehicular Technology, 2020This paper presents a detailed analysis of short circuit fault (SCF) in wound rotor (WR) resolvers. For this purpose, an analytical model based on winding function (WF) method is developed considering the stator and rotor windings’ fault, the severity of the fault, the phase of the stator faulty winding, and the tooth of shorted turns.

Diagnosis of Short-Circuit Faults in Combinational Circuits
IEEE Transactions on Computers, 1974Most work on diagnosis of digital circuits has concentrated on the model of stuck-type faults. Although these faults are probably the most important class of faults, other types of faults do occur in practice and the occurrence of these other faults may affect the diagnosis of stuck-type faults.

Short circuit faults in state-of-the-art ADCs - are they hard or soft?
Proceedings 10th Asian Test Symposium, 2002For next generation deep sub-micron (DSM) analogue and mixed signal ICs, the integration of Design-for-Test (DfT), Design for-Manufacturability (DfM), Defect-Oriented Test (DOT) approaches, and Built-In Self-Test (BIST) techniques into the design and manufacturing cycle will gain increasing importance to the context of implementing a structural IC test

A discussion on IGBT short-circuit behavior and fault protection schemes
IEEE Transactions on Industry Applications, 1995IGBTs are available with short-circuit withstand times approaching those of bipolar transistors. These IGBTs can therefore be protected by the same relatively slow-acting circuitry. The more efficient IGBTs, however, have lower short-circuit withstand times.

Hierarchical Agglomerative Clustering of Short-Circuit Faults in Transmission Lines
2008 10th Brazilian Symposium on Neural Networks, 2008Data mining can play a fundamental role in modern power systems. However, a major problem is to extract useful information from the currently available non-labeled digitized time series. This work proposes a new methodology based on hierarchical clustering for labeling faults that occurred in transmission lines.

Simulation of Short-Circuit Fault Occurring on Subway Train
2018Recently, with the large-scale development of subway, the safety of subway operation is attracting universal attention of the society. A short-circuit fault is a serious accident that threatens the safety of subway operation. The existing research focuses on the short-circuit fault occurring on the overhead line, but research on the short-circuit fault
