Severity Estimation of Interturn Short Circuit Fault for PMSM

IEEE Transactions on Industrial Electronics, 2019
This paper presents a novel method to estimate the number of shorted turns in a permanent magnet synchronous machine (PMSM) following the detection of interturn short-circuit (ITSC) fault and its location. In this proposed method, PMSM is excited through a low sinusoidal voltage at standstill condition to obtain the winding resistance and synchronous ...

A Comprehensive Analysis of Short-Circuit Current Behavior in PMSM Interturn Short-Circuit Faults

IEEE Transactions on Power Electronics, 2018
This 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 ...

Diagnosis of Short-Circuit Faults in Combinational Circuits

IEEE Transactions on Computers, 1974
Most 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.

Fault modelisation of external shorts in CMOS circuits

Proceedings of 1993 IEEE 2nd Asian Test Symposium (ATS), 2002
As the density of VLSI CMOS circuits increases, external shorts are expected to become a very important failure. This paper analyzes the electrical behavior of static CMOS gates with external shorts. The fault modelization of such shorts is then considered in the context of functional testing.

A Comprehensive Analysis of Short-Circuit Fault in Wound-Rotor Resolvers

IEEE Transactions on Vehicular Technology, 2020
This 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.

Test calculation for logic and short-circuit faults in digital circuits

2012 IEEE 16th International Conference on Intelligent Engineering Systems (INES), 2012
In the first part, the paper presents a test calculation principle which serves for producing tests of logic faults in digital circuits. The name of the principle is composite justification. The considered fault model includes stuck-at-0/1 logic faults. Both single and multiple faults are included.

Short circuit faults in state-of-the-art ADCs - are they hard or soft?

Proceedings 10th Asian Test Symposium, 2002
For 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, 1995
IGBTs 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.
