Abstract:
Direct current (DC) power systems are becoming very popular due to better control ability and equipment reliability thanks to the continuous development of power electronics. A DC circuit breaker (DCCB) used for current interruption in a DC network is a major part of the system. It plays the vital role of isolating networks during fault clearing as well as during normal load switching. Breaking the DC current is a major challenge as it does not have any natural zero crossing points like the AC current has. In addition, energy stored in the network inductances during normal operation opposes the instantaneous current breaking. Hence, all the conventional DC circuit breaker topologies use lossy elements to dissipate this stored energy as heat during the current breaking operation. However, it is possible to store this energy and reuse it later by developing an improvised topology. In this paper, the prospects of energy recovery and reuse in DC circuit breakers have been studied, and a new topology with regenerative current breaking capability has been proposed. This new topology can feed the stored energy of the network back into the same network after breaking the current and thus can improve the overall system efficiency.

Abstract:
Intégrées aux niveaux des interconnexions en technologies CMOS et BiCMOS, les inductances doivent répondre aux critères de fortes performances électriques, faible surface et/ou forts courants. Mais le défi n'est pas simple à relever. En effet, l'évolution du Back-End Of Line (BEOL) des technologies CMOS avancées et l'utilisation d'un substrat silicium à pertes tendent à dégrader fortement leurs performances. Ainsi, le développement de BEOL optimisés pour les inductances intégrées apparaît comme indispensable si on veut pouvoir répondre aux spécifications des circuits RF visés. Le principal objectif de cette thèse est de fournir des choix technologiques pour l'optimisation des inductances intégrées sur silicium, visant les applications dans la bande de fréquences de 1 à 5 GHz. Tout d'abord, une stratégie de gestion des inserts métalliques à l'échelle de l'inductance a été évaluée, afin de satisfaire les règles de densité imposées dans les technologies avancées (jusqu'au nœud technologique 32 nm). La volonté actuelle d'intégrer le module dédié à l'amplificateur de puissance en technologie CMOS a soulevé récemment la problématique de la gestion de forts courants (jusqu'à 1 A à 125°C) qui ne peut être adressée avec un BEOL standard. Un BEOL innovant utilisant deux niveaux de cuivre épais a été étudié en technologie CMOS 65 nm. Ce même BEOL a été évalué en technologie SOI. Cette dernière commence à émerger pour l'intégration du module d'émission complet en technologie CMOS de part sa compatibilité avec des substrats silicium Hautement Résistifs. L'optimisation d'inductances utilisant ce module double cuivre épais a été menée en technologie CMOS HR SOI 130 nm
Integrated in BEOL metallizations of CMOS or BiCMOS technologies, inductors have to meet requirements in terms of high electrical performances, low area and/or high current capability. However, this challenge is tricky to address. Actually, BEOL evolution and silicon substrate losses in Advanced CMOS technologies greatly decrease inductors' performances. Thus, the evaluation of optimized BEOL dedicated to the integration of inductors is essential if we want to target RF applications' specifications. The main objective of this thesis is to provide optimized technological solutions for inductors integrated in silicon technologies, and targeting RF applications in the 1 - 5 GHz frequency range. A dummy fill strategy has been evaluated at the scale of the device (without impacting its electrical performances) in order to fulfil metal density required in advanced technologies (down to the 32 nm node). Then, we have focused our attention on the evaluation of an optimized BEOL using a Double Thick Copper module in a 65 nm CMOS bulk technology. Actually, the wish to integrate the module dedicated to the power amplifier in CMOS technology has raised high current issues (up to 1 A @ 125°C), which is impossible to target with a standard BEOL. In the same trend, this optimized BEOL has been evaluated in SOI technology. Actually, this technology is starting to come up for the complete integration of the RF Front End module in CMOS technology thanks to its compatibility with HR silicon substrates which enables to integrate even more functions (antennas, diplexer, balun). Thus, inductor's optimization using a Double Thick Copper module has been performed in a 130 nm HR SOI CMOS technology

Abstract:
Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode.
Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.

For the development of the Internet of Things (IoT), wearable devices, and implantable medical devices, the wireless power transmission is receiving significant attention. In these applications, the external power from a transmitter is transmitted by the coils / antennas, and an AC voltage will be received in a wireless device. In the traditional wireless power transfer systems, the AC-DC conversion systems followed by the DC-DC conversion systems are used to generate an accurate voltage to safely charge a battery. Recently, the current-mode wireless power receivers are presented. By charging the battery with inductor current, the current-mode wireless power systems avoid rectification and voltage regulation. Therefore, the DC-DC conversion systems are spared and the PCE is improved. Also, the chip area and the off-chip components are reduced. This thesis presents a 13.56MHz current-mode wireless power receiver with energy-investment capability. When the system is in the charging mode, this work does not charge the output battery with all the power in the LC tank as the state-of-the-art systems do, this work reserves a fraction of energy stored as an investing voltage in the resonate capacitor instead. The investing voltage gives an initial voltage of the coil when this work finishes charging and starts to accumulate energy. The investing voltage increases the ability to grab energy from electromotive force (EMF). This work employs sample and holds circuits (SAHs) with low-frequency clocks to sample voltage and digital controlled delay lines (DCDLs) to control the switching timing of the power MOS. By this way, the operation frequency can be raised to 13.56MHz. High bandwidth circuits are avoided in the control circuits and power is saved. This work is fabricated in a 0.18-µm CMOS process and the active area is 0.341mm2. It achieves a peak PCE of 67.1% when the input power is 6mW.

Abstract:
Due to increasing penetration levels of renewable energy in the power system, it is essential to keep renewable energy resources connected to the power grid during a fault considering the grid code requirements. In this thesis, the Fault Ride Through (FRT) capability of wind turbines is taken into account. All types of wind turbines are considered and for each one, the proposed methods will be discussed and studied. In the first approach for Fixed Speed Wind Turbines (FSWTs), to achieve maximum FRT capability, this thesis proposes a single-phase Optimum Resistive Type Fault Current Limiter (OR-FCL) as an efficient solution during various grid faults. A dedicated control circuit is designed for the OR-FCL that enables it to insert an optimum value of resistance in the FSWT’s fault current path for improving transient behaviour of the FSWT. The optimum resistance value depends on fault location and pre-fault active power. The control circuit of the proposed OR-FCL is capable of calculating the optimum resistance value for all the pre-fault conditions. By using the proposed control circuit, the FSWT can achieve its maximum FRT capability during symmetrical and asymmetrical faults, even at zero grid voltage. In the second approach for the FSWTs, to reduce the number of components, a three-phase Controllable Resistive Type Fault Current Limiter (CR-FCL), with the same operation of the OR-FCL, is investigated to improve the FRT capability of the FSWT. Fully and partially rated converter wind turbines and solar power systems utilise an inverter to connect to the grid. The inverters are vulnerable due to their damaging effects of voltage sags in their terminals on semi-conductor self-turnoff switches. In this thesis, a Bridge Type Fault Current Limiter (B-FCL) is proposed with simple control system for the FRT improvement of the inverters during different types of faults. The proposed B-FCL located, in Point of Common Coupling (PCC), is also capable of compensating for the voltage sag in the PCC and creates safe conditions not only for the inverter but also for any equipment which has been connected to the PCC in the power system. In the second approach, to analyse the FRT capability of inverter interfaced distributed generation, and to reduce the number of components, an FCL is placed in the DC link. This thesis proposes a DC Link Resistive Type Fault Current Limiter (DC-RFCL) based-voltage source inverter (VSI) for the FRT capability improvement, which is a new approach in the use of FCLs. Instead of using three-phase FCLs in the AC side of the VSI as in the first approach, just one single-phase proposed DC-RFCL is connected in series with the DC side of the VSI. Doubly fed induction generator (DFIG)-based wind turbines employ small-scale voltage sourced converters with a limited over-current withstand capability, which makes the DFIG-based wind turbines very vulnerable to grid faults. Often, modern DFIG systems employ a crowbar protection at the rotor circuit to protect the rotor side converter (RSC) during the grid faults. This method converts the DFIG to a squirrel cage induction generator, which does not comply with the new grid codes. The recent grid codes require wind turbines to stay connected to the utility grid during and after the power system faults, especially under high penetration levels of wind power. Furthermore, the crowbar switch is expensive. Therefore, in this thesis, the FRT capabilities of DFIG-based wind turbines are studied. To improve the FRT capability of the DFIG-based wind turbines, three approaches are proposed: a modified DC chopper, a non-controlled FCL and a DC link resistive type fault current limiter. In the first approach, the modified DC-link chopper is proposed in order to maintain both the DC link voltage and the high current level in the stator and the rotor sides in a permissible level, without incorporating any extra fault current limiting strategies. In the second approach for the FRT improvement of the DFIG-based wind turbine, a non-controlled fault current limiter is proposed. Co-operative operation of the chopper circuit and the non-controlled FCL, which is located in the rotor side of the DFIG, are studied. It is demonstrated that locating the proposed topology on the rotor side is effective from the leakage coefficient point of view, limiting transient over-currents rather than on the stator side. Furthermore, it is shown that, by obtaining an optimum non-superconducting inductance value, the rate of the fault current change is limited to lower than the maximum rates of current change in the semi-conductor switches of the DFIG’s converters during the fault. In the third approach for the FRT improvement of the DFIG-based wind turbine, this thesis proposes the application of the DC Link Resistive Type Fault Current Limiter (DC-RFCL) to improve the FRT capability of the DFIG. The proposed DC-RFCL is employed on the DC side of the RSC. The DC-RFCL solves crowbar protection activation problems and eliminates subsequent complications in the DFIG system. The proposed DC-RFCL does not have any significant impact on the overall performance of the DFIG during normal operation. The proposed approach is compared with the crowbar-based protection method. Simulation studies are carried out using PSCAD/EMTDC software. In addition, a prototype is provided to demonstrate the main concept of the proposed approach.

In this paper, we present a [novel sentinel voltage control method] of external compensating driving circuit which could mainly be applied to the active-matrix organic light-emitting diode displays (AMOLED). The pixel driving current is gradually increased by the ramp voltage at gate and converted to voltage in real time. When the sensed voltage is equal to the sentinel voltage, the gate voltage stops changing. Thus, the gate voltage is pinched at the value corresponding to the target driving current. The pixel contains only three thin-film transistors (TFTs) and one capacitor, which is suitable for high PPI display. Owing to the small area of the high PPI pixel, the operation current of driving TFT may drop down to an extremely low level. However, this compensation circuit can work for low current level, even when the TFT is operated in the subthreshold where the current exponentially varies III with its gate voltage. Although the compensation circuit can be successfully operated, there are still some issue needs to solve when it works. Hence, we proposed an advanced version of this external compensation circuit in the following chapter. Regarding to different issue, we present multiply approaches to overcome them and make the circuit design complete. Thus, using these compensation circuit can conquer the operation difficulty of high PPI AMOLED and make external driver IC work simple by pinching off signal at expected value. Along with display panels in mobile devices, wearable devices, Augmented Reality (AR) products and Virtual Reality (VR) products being indispensable tools in recent years, these techniques are sure to be widely used.

Abstract:
This article examines capability deprivation as the basis for analyzing poverty. The capability approach, developed initially by Amartya Sen, questions the “informational space” on which considerations of poverty, inequality, justice, and so forth, should be based. According to the capability approach, the appropriate “space” for analyzing poverty is not what people have, nor how they feel, but what they can do and be. After providing an overview of the concepts that comprise the capability approach, this article discusses three key questions within the literature regarding the nature of the approach, namely: the question of functioning and/or capabilities, the question of a capability list, and the question of aggregation. It also describes some prominent empirical applications that have been inspired by the capability approach and concludes with an assessment of the current state-of-the-art literature on the capability approach.

Abstract:
This chapter presents Sen’s capability approach as a framework for well-being measurement with powerful and ongoing relevance to current work on measuring well-being in order to guide public policy. It discusses how preferences and values inform the relative weights across capabilities, then draws readers’ attention to measurement properties of multidimensional measures that have proven to be policy relevant in poverty reduction. It presents a dual-cutoff counting methodology that satisfies these properties and outlines the assumptions that must be fulfilled in order to interpret ensuing indices as measuring capability poverty. It then discusses Bhutan’s innovative extension of this methodology in the Gross National Happiness Index and reflects upon whether it might be suited to other contexts. It closes by responding at some length to relevant material in other Handbook chapters.

Abstract:
This final report provides a comprehensive and in-depth review of the current status of in-line inspection technologies including, but not limited to, Magnetic (Axial MFL, Circumferential MFL), and Geometrical (Caliper) methods in terms of their capabilities, limitations and potentials in detection, discrimination and characterization of various forms of pipeline mechanical damage, such as dents, dents with corrosion, and dents with cracks, gouges and dents with gouges. Capabilities of current technologies presented herein are based on validation data supplied by PRCI members. This report reviews and summarizes research regarding the capabilities of current in-line inspection (ILI) based technologies for the detection and discrimination of mechanical damage conducted by Blade Energy Partners in cooperation with participating ILI vendors and PRCI member pipeline operators. This research was conducted in two phases. The first identified the current deployed ILI technologies, vendor claims for capability and performance determination with validation data provided by the ILI vendors. Standardized performance measures were also developed and applied. The Phase I research was presented in an incomplete report, PR-328-063502-R01.

Full text
Abstract:
Stress-corrosion cracking (SCC) can occur in gas transmission pipelines. These cracks initiate on the exterior of the bulk pipe material and grow in the axial and radial direction. Access for comprehensive nondestructive inspection systems is generally limited to inside the pipe itself. Since these defects can lead to leaks and failures, a need of the gas pipeline industry is the in-line detection and characterization of stress-corrosion cracks. Previous research has shown the remote field eddy current (RFEC) technique can detect SCC in gas transmission lines. The objective of this program is to quantify the SCC detection and characterization capability of this technique. The internal nature of the RFEC technique identifies it as a potential candidate for in-line inspection. The through-transmission nature of RFEC technique is a major advantage over other nondestructive tests since it ensures the complete inspection of the entire pipe wall. This electromagnetic inspection technique requires no coupling agent to transmit inspection energy from a source, to the defect, and then to the sensor. If it can be shown that the RFEC technique is effective in detecting, identifying, and sizing SCC and other defects, the technique is a candidate for in-line inspection implementation.
