Abstract:
Network on chip (NoC) is a design space covered by the manifold combinations of network topology options, routing algorithms, switch architectures, fault tolerant mechanisms and so on. In NoC structures, switches and links are important components on network layers and the effect of faults on links and switches in NoC leads to disturbance in internal communication and low reliability. The performance reduction of many-core NoC architectures depend strongly on the number of faulty switches. This bottleneck motivates us to propose a fault tolerant switch in which the ring roads help the switch to tolerate the faulty ports and also faulty cores. In the proposed scheme, switch ports are connected via redundant ring roads and so the connection with adjacent nodes is not limited to one port. Moreover, if the switch core is defected, the node stays active and cooperates in packet forwarding process. The main advantages of the proposed scheme are tolerating the permanent faults on core and ports of a switch and handling the input traffic of a faulty switch by preventing the congestion around the faulty region. The simulation results verify the robustness of the proposed intelligent switch against various kinds of permanent faults in NoC architectures.

Abstract:
Introduction. Cascaded H-bridge multilevel inverters (CHB-MLI) are becoming increasingly used in applications such as distribution systems, electrical traction systems, high voltage direct conversion systems, and many others. Despite the fact that multilevel inverters contain a large number of control switches, detecting a malfunction takes a significant amount of time. In the fault switch configurations diode included for freewheeling operation during open-fault condition. During short circuit fault conditions are carried out by the fuse, which can reveal the freewheeling current direction. The fault category can be identified independently and also failure of power switches harmed by the functioning and reliability of CHB-MLI. This paper investigates the effects and performance of open and short switching faults of multilevel inverters. Output voltage characteristics of 5 level MLI are frequently determined from distinctive switch faults with modulation index value of 0.85 is used during simulation analysis. In the simulation experiment for the modulation index value of 0.85, one second open and short circuit faults are created for the place of faulty switch. Fault is identified automatically by means of artificial neural network (ANN) technique using sinusoidal pulse width modulation based on distorted total harmonic distortion (THD) and managed by its own. The novelty of the proposed work consists of a fast Fourier transform (FFT) and ANN to identify faulty switch. Purpose. The proposed architecture is to identify faulty switch during open and short failures, which has to be reduced THD and make the system in reliable operation. Methods. The proposed topology is to be design and evaluate using MATLAB/Simulink platform. Results. Using the FFT and ANN approaches, the normal and faulty conditions of the MLI are explored, and the faulty switch is detected based on voltage changing patterns in the output. Practical value. The proposed topology has been very supportive for implementing non-conventional energy sources based multilevel inverter, which is connected to large demand in grid.

Abstract:
This paper proposes a fault-detection method for open-switch failures in hybrid active neutral-point-clamped (HANPC) rectifiers. The basic HANPC topology comprises two SiC-based metal-oxide-semiconductor field-effect transistors (MOSFETs) and four Si insulated-gate bipolar transistors (IGBTs). A three-phase rectifier system using the HANPC topology can produce higher efficiency and lower current harmonics. An open-switch fault in a HANPC rectifier can be a MOSFET or IGBT fault. In this work, faulty cases of six different switches are analyzed based on the current distortion in the stationary reference frame. Open faults in MOSFET switches cause immediate and remarkable current distortions, whereas, open faults in IGBT switches are difficult to detect using conventional methods. To detect an IGBT fault, the proposed detection method utilizes some of the reactive power in a certain period to make an important difference, using the direct-quadrant (dq)-axis current information derived from the three-phase current. Thus, the proposed detection method is based on three-phase current measurements and does not use additional hardware. By analyzing the individual characteristics of each switch failure, the failed switch can be located exactly. The effectiveness and feasibility of the proposed fault-detection method are verified through PSIM simulations and experimental results.

Abstract:
Due to numerous advantages, a neutral point clamped (NPC) inverter is a preferred choice for high-power applications and renewable technology. The reliability of the NPC inverter is a major concerning factor during the assessment of system performance as power semiconductor switches are vulnerable to abnormal conditions. Open-circuit (OC) switch faults are not as dangerous as short circuit (SC) faults but eventually have enough potential to cause cascaded failure to other components in the system and thus need to be supervised carefully. The OC faults result in a distortion of voltage and current signals in the NPC converter. Based on these signals, over the past few years, many efforts have been made to identify and localize the OC switch fault to the switch level in the NPC topology. In this paper, a review of different OC switch fault diagnostic methods is provided. Starting from the NPC inverter operation under healthy and faulty conditions, the various possible and unavailable switching states along with the deviation in pole voltage under different switch fault conditions is discussed. Then, based on the approach used for system-based fault detection, the OC fault detection methods are classified. The various OC methods are further discussed on the basis of signal, i.e., current, voltage or a combination of both signals used as a signature for fault detection. Emphasis is given to the principle involved, diagnostic variables utilized, the implementation approach and the diagnostic time required. Finally, the approaches are tabulated so as to provide a quick reference for NPC fault diagnostics.

Abstract:
A new open-switch fault diagnosis method is proposed in this paper for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The single and multiple open-switch faults are detected without any additional equipment and complicated calculations since the proposed fault detection method is integrated with the hysteresis controller. The proposed fault-tolerant technique reduces the value of overcurrent and total harmonic distortion on the side phases of the faulty one, by changing the switching signal of one switch in its opposite phase in some regions. This technique is performed without adding any legs, switches, or triode for alternating currents to the circuit. Finally, the proposed fault-tolerant technique is evaluated by MATLAB simulation and the results show its effectiveness.

Abstract:
The risk of danger in industries is increasing due to the unexpected shutdowns owing to the unwanted faults in the components. These faults can also lead to a complete failure of the system causing costly production losses and safety issues. Therefore, Fault-Tolerant Control (FTC) techniques are used for such systems to get better reliability, and safety to prevent faults. This paper presents a Modified Triple Modular Redundancy (MTMR) based fault-tolerant system for a separately excited Direct Current (DC) motor with a Fault Detection and Isolation (FDI) unit that can detect, isolate, and replace the faulty switch with the standby switches to prevent the unwanted shut down of the system and support the process continuity thereby increasing reliability. The proposed MTMR will still be able to provide output with only one healthy switch with the other two in the faulty conditions. MATLAB/Simulink software was used for the experimentation process to check the performance of the system. The presented work establishes that the MTMR-based fault-tolerant H-bridge with the FDI unit is a highly reliable solution for the speed control of a separately excited DC motor. The comparison of the proposed work with existing works also demonstrates its superior performance.

Abstract:
Efficiency is turning into more and more necessary in power electronics. New applications are developed to reduce the consumption of en-ergy. Inverters that supply continuous quality power have vast use in solar energy based applications. For a Wind Turbine Generation sys-tem with neutral-point-clamped (NPC) topology in a back to back converter , good efficiency is provided when operated at high power. In NPC topology totally twelve switches are present. Input current distortion, torsion vibration and output current distortion is caused by open switch fault within NPC inverter and rectifier of the consecutive converter. Wind Turbine Generation systems will be erroneous due to such faults. Open-switch fault detection methodology is necessary for consecutive converters for enhancing the output of Wind Turbine Genera-tion systems. Our proposed work checks NPC rectifier and inverter for outer and inner open switch faults. Additionally for all the possible open-switch faults , a novel open-switch fault detection methodology within the back to back converter has been presented in this paper.

Abstract:
The multilevel inverter-based drive system is greatly affected by several faults occurring on switching elements. A faulty switch in the inverter can potentially lead to more losses, extensive downtime and reduced reliability. In this paper, a novel fault identification and reconfiguration process is proposed by using discrete wavelet transform and auxiliary switching cells. Here, the discrete wavelet transform exploits a multiresolution analysis with a feature extraction methodology for fault identification and subsequently for reconfiguration. For increasing the reliability, auxiliary switching cells are integrated to replace faulty cells in a proposed reduced-switch 5-level multilevel inverter topology. The novel reconfiguration scheme compensates open circuit and short circuit faults. The complexity of the proposed system is lower relative to existing methods. This proposed technique effectively identifies and classifies faults using the multiresolution analysis. Furthermore, the measured current and voltage values during fault reconfiguration are close to those under healthy conditions. The performance is verified using the MATLAB/Simulink platform and a hardware model.

Abstract:
Artificial intelligence (AI) techniques are widely used in fault diagnosis because they are superior in detection and prediction. The detection of faults in power systems containing electronic components is critical. The switch faults of the voltage source inverter (VSI) have a severe impact on the driving system. Short-circuit switches increase the thermal stress due to their fast and high stator currents. Additionally, open-circuit switches cause unstable motor operation. However, these issues are not sufficiently addressed or accurately predicted for VSI switch faults in the literature. Thus, this paper investigates the use of different AI classifiers for three-phase VSI fault diagnosis. Various AI methods are used, such as naïve Bayes, support vector machine (SVM), artificial neural network (ANN), and decision tree (DT) techniques. These methods are applied to a VSI-fed permanent magnet synchronous motor (PMSM) to detect the faults in the inverter switches. These methods use the drain–source voltage and PWM signals to decide whether the switch is healthy or unhealthy. In addition, they are compared in terms of their detection accuracy. In this regard, the comparative results show that the DT method has the highest accuracy as compared to other methods in the fault diagnosis process. Moreover, this paper proposes a novel and universal voltage compensation loop to compensate for the absence of the voltage portion due to the open switch fault. Thus, the driving system is assisted in operating under its normal operating conditions. The universal term is used because the proposed voltage compensation loop can be implemented in any type of inverter. To validate the results, the proposed system is implemented using two software programs, LTSPICE XVII-USA, WEKA 3.9-New Zealand.

Abstract:
A new switch-level fault simulation method for MOS circuits is presented that combines compiled switch-level simulation techniques and functional fault modeling of transistor faults with the new fault simulation algorithm of differential fault simulation. The fault simulator models both node stuck-at-0, stuck-at-1 faults and transistor stuck-on, stuck-open faults. Prior to simulation, the switch-level circuit components are compiled into functional models. The effect of transistor faults on the function of the circuit components is modeled by functional fault models that execute very fast during simulation. Every compiled circuit component is assigned a dominance attribute, which abstracts relative strength information in the circuit. Dominance is used during simulation to resolve the X-state due to fighting pull-up and pull-down transistor paths and also to deduce transistor fault detectability and fault equivalencies prior to simulation. The differential fault simulation algorithm developed for gate-level circuits is adapted for use at the switch-level. Differential fault simulation provides excellent performance with minimum memory requirements, although it incurs a higher overhead at the switch-level than at the gate-level due to the dynamic memory properties of MOS circuits.

Abstract:
In the future, the performance of the railway system must be improved to accommodate increasing passenger volumes and service quality demands. Track switches are a vital part of the rail infrastructure, enabling traffic to take different routes. All modern switch designs have evolved from a design first patented in 1832. However, switches present single points of failure, require frequent and costly maintenance interventions, and restrict network capacity. Fault tolerance is the practice of preventing subsystem faults propagating to whole-system failures. Existing switches are not considered fault tolerant. This thesis describes the development and potential performance of fault-tolerant railway track switching solutions. The work first presents a requirements definition and evaluation framework which can be used to select candidate designs from a range of novel switching solutions. A candidate design with the potential to exceed the performance of existing designs is selected. This design is then modelled to ascertain its practical feasibility alongside potential reliability, availability, maintainability and capacity performance. The design and construction of a laboratory scale demonstrator of the design is described. The modelling results show that the performance of the fault tolerant design may exceed that of traditional switches. Reliability and availability performance increases significantly, whilst capacity gains are present but more marginal without the associated relaxation of rules regarding junction control. However, the work also identifies significant areas of future work before such an approach could be adopted in practice.

Abstract:
La pile à combustible, en raison de son faible niveau de tension de fonctionnement et de sa caractéristique volt-ampèremétrique non linéaire, nécessite la présence d’un convertisseur statique de type DC-DC pour la relier à la charge dans le but d’augmenter le niveau de tension et de réguler cette dernière à une valeur constante. Le convertisseur DC-DC du type hacheur élévateur à phases parallèles et à commandes entrelacées est un choix intéressant de part une conception assez simple, une bonne fiabilité, une faible ondulation du courant d'entrée, ce qui est bénéfique pour le fonctionnement à long terme de la pile à combustible. Cependant, le contrôle de cette topologie de convertisseur doit prendre en compte certains critères comme les incertitudes de valeurs au niveau des composants passifs (résistance parasite et tolérance d'inductance / capacité) et des perturbations de l’association pile à combustible – convertisseur – charge (variations du courant de charge et de la tension de la pile à combustible selon le point de fonctionnement envisagé et prise en compte des défauts électriques internes au convertisseur). Dans le but d'améliorer les performances statique et dynamique du système pile à combustible en modes de fonctionnement sain et défaillant, la commande du convertisseur à phases parallèles et à commandes entrelacées avec prise en compte de la robustesse face aux perturbations internes et externes est étudiée dans cette thèse.Pour mieux gérer les incertitudes liées aux paramètres électriques du convertisseur et les perturbations externes (pile à combustible ou charge), un contrôleur de tension robuste basé sur un observateur d'état étendu (ESO) dans le cadre de l'algorithme de contrôle actif du rejet de perturbation (ADRC) est proposé et appliqué à la topologie de convertisseur envisagée pour une application pile à combustible. La comparaison avec le contrôleur du type PI montre que la méthode proposée peut obtenir une meilleure capacité de rejet des perturbations sans dépassement de la réponse à la suite d’un échelon du courant de charge ou à une variation du niveau de tension d’entrée. Le contrôleur proposé est également validé sur une seconde topologie de convertisseur qui est une variante de la première et permettant un gain d’élévation en tension plus élevé.L’apparition d’un défaut électrique sur les interrupteurs de puissance du convertisseur entraîne généralement la perte d’une phase de celui-ci. Ceci occasionne des effets néfastes considérables sur les performances du contrôleur. Par conséquent, un contrôleur adaptatif amélioré, avec la prise en compte des défauts électriques sur les interrupteurs est proposé sur la base du contrôleur développé précédemment. Le contrôleur proposé peut maintenir un fonctionnement continu et obtenir de bonnes performances en cas de défauts. De plus, une méthode de diagnostic basé-modèle de défauts d’interrupteurs de puissance en s’appuyant sur un observateur de mode glissant est proposée et appliquée au système pile à combustible étudié. L'approche proposée dans ce manuscrit permet de diagnostiquer efficacement un défaut d’interrupteur de puissance et de montrer une forte robustesse à l'incertitude des paramètres du convertisseur et aux perturbations externes. Enfin, pour optimiser l'ondulation du courant d'entrée élevée à la suite de la perte d’une phase du convertisseur provoquée par un défaut sur l’un des interrupteurs, une nouvelle méthode de reconfiguration de la commande en appliquant une adaptation du déphasage entre les phases restantes est proposé. En comparaison avec une reconfiguration classique par un déphasage uniforme entre les phases, celle proposée permet une réduction significative de l'ondulation du courant d’entrée après l’apparition, la détection et la reconfiguration d’un défaut. Les différentes méthodes proposées sont toutes validées par des résultats de simulation et expérimentaux
The relatively low voltage and the nonlinear volt-ampere curve of the fuel cell (FC) stack necessitate the interface with the DC-DC power converter, in order to boost and regulate a constant DC bus voltage to satisfy the load requirement. The multi-phase interleaved converter by associating basic converter units via parallel structure is an attractive choice. It features high reliability, and it enables a low input current ripple via phase interleaving, which is beneficial for the long-time operation of the FC stack. The converter for FC application suffers from the converter uncertainties (parasitic resistance and inductance / capacitance tolerance), the external disturbances (dynamic load demand on the output side and variable source voltage on the input side), and the device fault (e.g., switch fault) uncertainty. Aiming to improve the steady-state and dynamic performance under healthy and switch fault mode of the system, the control of the interleaved converter with switch fault consideration for FC application is studied in this thesis.To better deal with the converter uncertainty and external disturbance, a robust voltage controller based on extended state observer (ESO) within the framework of active disturbance rejection control (ADRC) algorithm is proposed and applied to an interleaved boost converter for FC application. The comparison with PI control shows that the proposed method can achieve better disturbance rejection ability without overshoot in step response. The application of the proposed method to another interleaved converter (i.e., floating interleaved boost converter, FIBC) validates again its feasibility.The switch fault generally leads to the loss of the phase of the interleaved converter, which has considerable adverse effects on the controller performance. Therefore, an improved adaptive controller is proposed and applied to a FIBC with switch fault consideration, based on the previously developed controller. The proposed controller adapts the parameter in real-time. It can maintain continuous operation and achieve good performance in both healthy and switch fault mode. Furthermore, a switch fault diagnosis method based on sliding mode observer is proposed and applied to the FIBC for FC application. The proposed approach can diagnose the switch fault effectively, and it shows strong robustness to the converter uncertainties and external disturbances. Finally, to optimize the undesired high input current ripple of the FIBC caused by the switch fault, a novel post-fault control method by applying uneven phase shift reconfiguration is proposed. In comparison with the even phase shift reconfiguration, the proposed one can achieve significant improvement in reducing the post-fault current ripple. The effectiveness of the proposed methods is validated by the simulation and experimental results

Abstract:
The present thesis deals with fault impact mitigation in grid connected converters used for High Voltage Direct Current transmission. Certain critical fault cases require additional obstructing protection actions to ease the impact on the converter valves. DC sided faults drives high fault currents through the converters. Single phase to ground faults at the converter AC bus results in overvoltages across the converter valve arms. The phenomenon of these faults are described both for symmetric and asymmetric configurations. Different available solutions are explained and evaluated. Simulations in PSCAD/EMTDC show the impact of the protection measures. A three phase short circuit introduced on the tertiary winding of the transformer is an effective temporary measure against the destructive fault cases. It is shown in this report that a tertiary shortcircuit will greatly reduce the overvoltages after converter bus faults and redirect a large part of the fault currents after DC faults. With the lower voltage on the tertiary winding, it is a suitable connection point for short circuit devices.

Abstract:
Large-scale changes are common in genomes, and are often associated with pathological disorders. In the work presented in this dissertation, I provide insights into how inverted repeat sequences in budding yeast fuse during replication. Fusion leads to the formation of dicentric chromosomes, a translocation, and other chromosomal rearrangements.Using extensive genetics and some molecular analyses, I demonstrate that dicentric chromosomes are key intermediates in genome instability of a specific chromosome in budding yeast. I provide three pieces of evidence that is consistent with this conclusion. First, I detect a recombination fusion junction that is diagnostic of a dicentric chromosome (using a PCR technique). Second, I show a strong correlation between the amount of the dicentric fragment and the frequency of instability of the entire chromosome. Third, I demonstrate that a mutant known to stabilize dicentric chromosomes suppress instability. Based on these observations, I conclude that dicentric chromosomes are intermediates in causing genome instability in this system.Next, we demonstrate that fusion of inverted repeats is general. Both endogenous and synthetic nearby inverted repeats can fuse. Using genetics, I also show that many DNA repair and checkpoint pathways suppress fusion of nearby inverted repeats and genome instability. Based on our analysis, we propose a novel mechanism for fusion of inverted repeats that we term `faulty template switching.'Lastly, I discuss two genes that are necessary for fusion of nearby inverted repeats. I identified a mutant of the Exonuclease 1 (Exo1) and a mutant of anaphase inhibitor securin (Pds1) that suppress nearby inverted repeat fusion and genome instability. Studies of Exo1 and Pds1 provide us with insights into the molecular mechanisms of fusion.Our finding that nearby inverted repeats can fuse to form dicentric chromosomes that lead to genome instability may have great implications. The generality of this fusion reaction raises the possibility that dicentric chromosomes formed by inverted repeats can lead to genome instability in mammalian cells, and thereby contribute to a cancer phenotype.

Abstract:
As the core equipment to control the running direction of railway vehicle, the turnout switch machine, its failure will lead to a series of problems. At present, more and more researchers conduct intelligent re-search on its fault diagnosis. In this paper, aiming at different types of faults during the operation of turnout switch machines, a spiking neural networks model based on apoptosis mechanism (BASNNs) is established as a classifier for fault diagnosis. The model uses neuron competition rules and intelligent unsupervised learning algorithms to update the network. The system uses the non-contact measurement of the sound signal as the input, and uses the combination of empirical mode decomposition (EMD) and wavelet packet decomposition energy entropy (WPDE) to extract features of the sound data. Experimental results show that the proposed method has better data recognition ability than traditional ANNs with the same number of layers.

Abstract:
A novel fault adaptive control methodology for a mobile robot is presented in this paper. A bond-graph based modeling technique is used for fault detection and isolation. A hierarchical control accommodation framework is developed for a supervisory controller that determines a suitable control strategy to accommodate the isolated fault. It is shown in the paper that for small degradations, a robust controller achieves fault accommodation without significant loss of performance. However, for large faults, the supervisor needs to switch among several controllers to maintain acceptable performance. Simulation results verify the proposed fault adaptive control technique for a mobile robot.
