Abstract:
Interleaved zero-voltage switching boost converters have been known for over 20 years. However, the influence of parasitic capacitance of transistors has not been described. In this paper the converter is analyzed and the equation for voltage ratio is derived for any number of converter phases. First a general description of the topology, including main voltage and current waveforms, is provided. Subsequently the converter is analyzed and conditions for soft switching are derived. Next the analysis results are compared to measurements of an experimental converter setup. Discrepancies are identified and the influence of parasitic capacitance is analyzed. By considering the parasitic capacitance the difference between experimental and analytical results of voltage ratio is reduced from 0.2 to less than 0.05.

Abstract:
This paper presents an analysis of the influence of parasitic inter-electrode capacitances of the components of logarithmic analogue-to-digital converters with successive approximation with a variable logarithm base. Mathematical models of converter errors were developed and analyzed taking into account the parameters of modern components. It has been shown that to achieve satisfactory accuracy for the 16 bit LADC, the capacitance of the capacitor cell must not be less than 10 nF; for the 12 bit LADC, 1 nF is sufficient.

Abstract:
To achieve various conversion ratios with high power efficiency, a symmetrical digital selecting type switched-capacitor (SC) DC-DC converter with power saving techniques is proposed in this paper. Unlike conventional SC DC-DC converters, the voltage ratio of capacitors is expressed as the ratio of a power of two. By combining some of these capacitors in series, the proposed converter can achieve a larger number of conversion ratios than conventional converters. Furthermore, by employing a symmetrical structure with power saving techniques, the proposed converter can alleviate energy loss due to stray parasitic capacitance. The theoretical analysis and SPICE simulations show the effectiveness of the proposed converter.

This paper introduces three methods to increase the output power of the vibration based electrostatic MEMS energy converters. This will be done by taking the effect of the parallel capacitance of the converter in the output power equation. In addition the output power of the converter will be increased by two other ways: Firstly, by depositing dielectric materials on the sidewalls of the converter fingers, secondly, by increasing the converter thickness. In addition the output power will be increased to an optimum value by combining the effect of increasing the device thickness and depositing dielectric materials on the sidewalls of the converter fingers.

Abstract:
In this paper three embedded switched capacitor based DC–DC converters targeting Vdd/2, 2Vdd/3, and Vdd/3 output voltages have been designed with improved power efficiency and output voltage ripple. The performance of each of the converter is improved by nonoverlapped rotational time interleaving (NRTI) switching scheme. Current regulation scheme is included with each of the above NRTI switched capacitor converter to achieve better load and line regulation. The proposed converters are designed and simulated in a 0.18 μm n-well CMOS process with the total flying capacitance of 330 pF and load capacitor of 50 pF. The capacitance values are kept within on-chip implementable range. The maximum power efficiency and the output voltage ripple of the integrated NRTI DC–DC converters targeted for Vdd/2, 2Vdd/3 and Vdd/3 output generation are 71.5% and 5 mV, 69.23% and 13.27 mV and 58.09% and 10.5 mV, respectively.

Abstract:
Power Factor Correction (PFC) converters are widely used in engineering. A classical PFC control circuit employs two complicated feedback control loops and a multiplier, while the One-Cycle-Controlled (OCC) PFC converter has a simple control circuit. In OCC PFC converters, the voltage loop is implemented with a PID control and the multiplier is not needed. Although linear theory is used in designing the OCC PFC converter control circuit, it cannot be used in predicting non-linear phenomena in the converter. In this paper, a non-linear model of the OCC PFC Boost converter is proposed based on the double averaging method. The line frequency instability of the converter is predicted by studying the DC component, the first harmonic component and the second harmonic component of the main circuit and the control circuit. The effect of the input voltage and the output capacitance on the stability of the converter is studied. The correctness of the proposed model is verified with numerical simulations and experimental measurements.

Abstract:
This thesis presents the simulation, design, and hardware implementation of a modified multiphase boost converter. Converter design must consider noise imposed on input and output nodes which connect to and influence the operation of other devices. Excessive noise introduces EMI which can damage sensitive circuits or impede their operation. High ripple current degrades battery lifetime and reduces operating efficiency in connected systems such as PV arrays. Converters with high ripple current also experience greater peak conduction loss and require larger components. A two-phase implementation of a modified boost converter demonstrates the input current filtering benefits of the modified topology with increased power capacity. In a 12V to 19V 95W design, the modified multiphase design exhibits a reduced input current ripple of 1.103% compared to the 9.096% of the standard multiphase design while imposing minimal detriment to overall converter efficiency. The modified topology uses two inductors and one feedback capacitance per phase. Larger value inductors generally exhibit lower current ratings as well as larger size. The split inductance of the modified multiphase topology can be designed for occupation of less total volume than the single inductance of the standard multiphase topology.

Abstract:
Switched reluctance motor (SRM) has become a competitive selection for many applications of electric machine drive systems recently due to its relative simple construction and its robustness. The advantages of those motors are high reliability, easy maintenance and good performance. The absence of permanent magnets and windings in rotor gives possibility to achieve very high speeds (over 10000 rpm) and turned SRM into perfect solution for operation in hard conditions like presence of vibrations or impacts. Such simple mechanical structure greatly reduces its price. Due to these features, SRM drives are used more and more into aerospace, automotive and home applications. The major drawbacks of the SRM are the complicated algorithm to control it due to the high degree of nonlinearity, also the SRM has always to be electronically commutated and the need of a shaft position sensor to detect the shaft position, the other limitations are strong torque ripple and acoustic noise effects.

Este documento apresenta uma nova técnica para a minimização da ondulação de baixa frequência, típica de conversores para o acionamento de LEDs alimentados a partir da rede elétrica. Esta estratégia baseia-se na modulação em baixa frequência da razão cíclica do conversor de modo que a ondulação de corrente possa ser reduzida e, consequentemente, as capacitâncias de filtragem do conversor possam ser minimizadas. Esta técnica foi desenvolvida para a aplicação em conversores de malha única, como é o caso de conversores de estágio único ou mesmo dois estágios integrados. A modulação da razão cíclica é projetada de maneira que o comportamento de baixa frequência das principais variáveis do conversor seja alterado, permitindo uma redução da ondulação da corrente de saída ao custo de um incremento cotrolado no conteúdo harmônico da corrente de entrada. Duas possíveis metodologias para a implementação da técnica proposta são discutidas ao longo do trabalho. A primeira envolve a injeção de harmônicas específicas no sinal da razão cíclica do conversor através de ramos adicionais na estrutura de controle. Esta abordagem foi aplicada para projetar um controlador de LEDs baseado em um conversor flyback e também em uma topologia integrada baseada na conexão cascata de dois conversores Buck-boost. Este estudo inicial foi expandido para outros conversores e uma análise generalizada acerca da influência da modulação da razão cíclica no comportamento de controladores de LED alimentados a partir da rede elétrica é apresentada. A segunda metodologia para a implementação da compensação ativa da ondulação de baixa frequência do conversor é baseada na otimização de um controlador proporcional-integral a fim de que tal elemento influencie não só no comportamento dinâmico do circuito, mas também na característica de baixa frequência do conversor. Por fim são discutidas as principais contribuições da tese e algumas propostas para trabalhos futuros são apresentadas
This document presents a novel approach for low-frequency output current ripple minimization in off-line light-emitting diode (LED) drivers. This strategy is based on the large-signal modulation of the duty-cycle so that the output ripple can be reduced and, consequently, the required filtering capacitances of the converter can be somehow decreased. This technique is devised to be used on converters in which a single control loop is employed, such as off-line single-stage or integrated converters. The duty-cycle modulation is used to change the shape of the main waveforms of the converter, especially the input and output currents. This allows for a reduction of the output current peak-to-peak ripple while the harmonic content of the input current is increased but kept within the limits imposed by the IEC standard. Two methodologies for implementing the proposed technique are discussed along the text. The first one is related to the injection of harmonic components to the duty cycle signal by means of additional branches inserted in the conventional control structure. This approach was applied to design an off-line flyback-based LED driver and also a circuit based on the Integrated Double Buck-boost converter. This first study was expanded to other topologies and a generalized analysis regarding the impact of the duty cycle modulation on off-line converters is then presented. The second methodology for implementing the ripple compensation is based on the optimization of a proportional-integral controller so that this element is designed to influence not only in the dynamic behavior of the circuit, but also in its low-frequency characteristic. Finally, the main contributions of this work are discussed and the proposals for future works are presented.

Abstract:
Frequency reference oscillator is a critical component of modern radio transceivers. Currently, most reference oscillators are based on low-frequency quartz crystals that are inherently bulky and incompatible with standard micro-fabrication processes. Moreover, their frequency limitation (<200MHz) requires large up-conversion ratio in multigigahertz frequency synthesizers, which in turn, degrades the phase-noise. Recent advances in MEMS technology have made realization of high-frequency on-chip low phase-noise MEMS oscillators possible. Although significant research has been directed toward replacing quartz crystal oscillators with integrated micromechanical oscillators, their phase-noise performance is not well modeled. In addition, little attention has been paid to developing electronic frequency tuning techniques to compensate for temperature/process variation and improve the absolute frequency accuracy. The objective of this dissertation was to realize high-frequency temperature-compensated high-frequency (>100MHz) micromechanical oscillators and study their phase-noise performance. To this end, low-power low-noise CMOS transimpedance amplifiers (TIA) that employ novel gain and bandwidth enhancement techniques are interfaced with high frequency (>100MHz) micromechanical resonators. The oscillation frequency is varied by a tuning network that uses frequency tuning enhancement techniques to increase the tuning range with minimal effect on the phase-noise performance. Taking advantage of extended frequency tuning range, and on-chip temperature-compensation circuitry is embedded with the sustaining circuitry to electronically temperature-compensate the oscillator. Finally, detailed study of the phase-noise in micromechanical oscillators is performed and analytical phase-noise models are derived.

Abstract:
Les dispositifs DBD se répandent dans un grand nombre d’applications industrielles. Utilisés depuis plus de 150 ans pour la production d’ozone afin de décontaminer l’eau à grande échelle, ils ont depuis la fin du XXème siècle investi les domaines du traitement de surface polymère, du dépôt de couche mince sur substrat et de l’émission lumineuse pour la décontamination ainsi que la médecine. Ces dispositifs sont mis en oeuvre avec un générateur électrique dont les caractéristiques impactent fortement la qualité de la décharge. Ce travail s’inscrit en partie dans le cadre du développement d’une application de traitement de surface à pression atmosphérique. Il aborde la problématique de l’augmentation de la vitesse de dépôt de couche mince au travers des paramètres de l’alimentation électrique. Plus précisément, ce travail s’intéresse aux apports d’une alimentation en courant rectangulaire et aborde également les problématiques liées à la conception et à la fabrication de ce convertisseur. En particulier, une grande attention est portée sur l’étude du transformateur élévateur, car au travers de ses éléments parasites capacitifs, ce dernier peut limiter le transfert de puissance entre la source électrique et le dispositif DBD. Un deuxième aspect de cette étude consiste à entrevoir l’intérêt que revêtent deux convertisseurs statiques dédiés à l’alimentation de dispositifs DBD. Le premier consiste en une alimentation résonante en régime de conduction discontinue dont la particularité est de posséder trois degrés de liberté (fréquence, tension d’entrée et largeur d’impulsion), ce qui lui confère un intérêt exploratoire. Le second convertisseur consiste en une alimentation résonante haute tension et haute fréquence permettant l’éviction du transformateur élévateur, et mettant en oeuvre des interrupteurs au nitrure de gallium (GaN) afin d’atteindre une fréquence de fonctionnement supérieure au mega-Hertz avec un faible niveau de pertes.

De nos jours, les capteurs capacitifs sont largement utilisés dans la mesure de grandeurs physiques telles que le déplacement, l’humidité, la pression, etc. Cette large diffusion est principalement due au développement des technologies MEMS qui ont permis de réduire leur coût, leur taille et leur consommation. Pour mesurer ces variations de capacité, des interfaces de conditionnement électronique ont été développées afin d’obtenir un signal électrique exploitable tel qu’une tension, un courant, un temps, une fréquence ou directement une sortie numérique. C’est dans ce cadre que se positionne l’objectif de cette thèse ; étudier la faisabilité d’une mesure capacitive à sortie numérique à partir d’un pont actif, une architecture développée et brevetée par l’équipe Conception et Test de Microsystèmes du LIRMM pour le conditionnement de capteurs résistifs basse consommation. La conversion numérique utilisée est une modulation Sigma-Delta 1 bit du 1er ordre, relativement facile à implémenter, et donc bien adaptée à l’intégration, à la faible consommation et à la réalisation d’interfaces génériques. Pour le retour 1 bit, deux structures de contre réaction ont été proposées : une contre-réaction résistive et une capacitive. Les résultats théoriques sont comparés à des résultats de simulations et à des mesures obtenues à partir des prototypes fabriqués en technologie CMOS 0,35μm d’Austria MicroSystem (AMS)
Nowadays, capacitive sensors are widely used in the measurement of physical quantities such as displacement, humidity, pressure, etc. This wide dissemination is mainly due to the development of MEMS technologies that have reduced their cost, size and consumption. To measure these capacitance changes, sensor electronic interfaces have been developed to obtain an exploitable electrical signal such as voltage, current, time, frequency or directly a digital output. It is in this framework that the aim of this thesis is positioned ; to study the feasibility of a capacitive measurement with digital output from an active bridge, an architecture developed and patented by the Design and Test Microsystems team of LIRMM for conditioning low power resistive sensors. The digital conversion used is a one-bit first-order Sigma-Delta modulation that is relatively easy to implement, and is well adapted to integration, low power consumption and realization of generic sensor interfaces. Two feedback architectures have been proposed: a resistive feedback and a capacitive. The theoretical results are compared with the results of simulations and measurements obtained from prototypes fabricated using a 0.35μm CMOS technology from Austria MicroSystem (AMS)

Abstract:
It is essential to always track maximum power from photovoltaic (PV) sources. Failure to track the global maximum power point under partial shading conditions is one of the major reasons that lead to significant power losses. Several maximum power point tracking methods have been proposed to deal with this problem. However, none of them were able to effectively identify the occurrence of partial shading. With the facility of Matlab modelling and simulation as well as the aid of a constructed solar emulator, the power-voltage characteristics of a PV panel under uniform and non-uniform irradiance conditions have been studied and some useful conclusions have been identified from observation. Based on these conclusions, a novel maximum power point tracking algorithm has been proposed, which is capable of identifying the occurrence of partial shading hence determining the need for a global scan over the operation range of PV panels for the true maximum power point. In the meantime, the effect of PV dynamics, due to the capacitance of PV cells, on maximum power point trackers has been investigated and some initial results and suggestions have been presented in this work.

Abstract:
This master thesis presents the development of a 100 W LED driver, suitable for outdoor and street lighting. In order to match the driver and LED features, special functionalities are added to the electronic system. To obtain a long lifetime, electrolytic capacitor are exchanged by film capacitor, with longer useful lifetime. However, this practice outcome in higher bus voltage ripple, which have to be compensated in the LED current control stage, named as power control stage. To achieve special functionalities, the proposed driver is designed to operate with universal input voltage and dimming capability, being the entire driver control implement in a digital way, increasing significantly the LED driver flexibility. After the literature review, which aimed to evaluate the characteristics of the LED driver topology structure, the two independent stage topology is selected. The buckboost converter operating in discontinuous conduction mode is employed on the power factor correction stage. The power control stage is composed by the DC/DC LLC resonant converter. Once the LED driver topology is defined, each converter is designed, following by the small signal modeling and the control system design. Experimental results of the driver operating with a reduced bus voltage capacitance (25 μF), are presented for a universal input voltage (85 – 265 VRMS) and different dimming levels (100% − 30%). A high power factor (> 0,94) and a medium to high efficiency (> 82%) is noticed in whole operation points, as well as, a reduced flicker (< 10%), being in accordance with the recent released IEEE Std 1789-2015 and IEC61000-3-2 Class C.
Este trabalho apresenta o desenvolvimento de um driver para o acionamento de um módulo de LEDs de 100 W, destinado a iluminação de exteriores ou iluminação pública. De forma a compatibilizar as características do LED com o driver, diferentes funcionalidades e condições de operação são adicionadas ao sistema eletrônico desenvolvido. Para alcançar longa vida útil, o driver desenvolvido substituiu os capacitores eletrolíticos por capacitores de filme. No entanto, essa prática resulta em maiores ondulações da tensão de barramento, as quais são compensadas pelo estágio de controle da corrente dos LEDs. De modo a aumentar as funcionalidades do driver, o mesmo opera com tensão de entrada universal e controle da intensidade luminosa, sendo o sistema de controle do driver implementado de forma digital, aumentando consideravelmente sua flexibilidade. Após revisão da literatura, a qual objetivou avaliar as características das estruturas e topologias empregadas em drivers para LEDs, seleciona-se a estrutura de dois estágios independentes. O conversor buck-boost operando no modo de condução descontínuo de corrente é empregado no estágio de correção do fator de potência. Para o estágio de controle da corrente dos LEDs, utiliza-se o conversor CC/CC meia ponte ressonante LLC. Definida a estrutura topológica, bem como os conversores utilizados, o projeto dos elementos é desenvolvido, seguido da modelagem dinâmica e do projeto do sistema de controle de cada estágio. Resultados experimentais do driver com reduzida capacitância de barramento (25 μF) mostram a sua operação com tensão de entrada universal (85 – 265 VRMS) e controle de intensidade luminosa (100% − 30%). Verificou-se um alto fator de potência (> 0,94) em toda a faixa de operação, rendimento média-alto (> 82%), bem como reduzida modulação de intensidade luminosa (< 10%), estando em conformidade com a IEEE Std 1789-2015 e a IEC61000-3-2 Classe C.

Abstract:
This chapter presents state-of-the-art and major developments in wireless power transfer using solar energy. The brief state-of-the-art is presented for solar photovoltaic technologies which can be combined with wireless power transfer (WPT) to interact with the ambient solar energy. The main purpose of the solar photovoltaic system is to distribute the collected electrical energy in various small-scale power applications wirelessly. These recent developments give technology based on how to transmit electrical power without any wires, with a small-scale by using solar energy. The power can also be transferred wirelessly through an inductive coupling as an antenna. With this wireless electricity we can charge and make wireless electricity as an input source to electronic equipment such as cellphone, MP3 Player etc. In harvesting energy, technologies of ambient solar radiation like solar photovoltaic, kinetic, thermal or electro-magnetic (EM) energy can be used to recharge the batteries. Radio frequency (RF) harvesting technologies are also popular as they are enormously available in the atmosphere. The energy converted to useful DC energy which can be used to charge electrical devices which need low power consumption. The chapter has also presented a parallel plate photovoltaic amplifier connected to a potentiometer as a Resistance-Capacitance (RC) circuit power amplifier. The effect of inductance and resulting power transfer has been theoretically determined in the RC amplifier circuit. The electrical and thermal properties and measurements from a parallel plate photovoltaic amplifier were collected to analyze the unbalanced power transfer and inductance in a nonlinear RC circuit amplifier using equivalent transfer functions. The concept of Wireless Information and Power Transfer using Electromagnetic and Radio Waves of Solar Energy Spectrum is also briefly outlined.
