Abstract:

Recent research activities focused on improving the steady-state as well as the dynamic behavior of DC-DC converters for proper system performance, by proposing different design methods and control approaches with growing tendency to using digital implementation over analog practices. Because of the rapid advancement in semiconductors and microprocessor industry, digital control grew in popularity among PWM converters and is taking over analog techniques due to availability of fast speed microprocessors, flexibility and immunity to noise and environmental variations. Furthermore, increased int

Abstract:

This work demonstrates the design and implementation of a digitally encoded Sinusoidal Pulse Width Modulation strategy for the switching of bi-directional secondary side power switches of an AC-link. Through this method, high frequency (200 kHz) half sinusoid or haversine voltage pulses produced by the Parallel Loaded Resonant converter working in discontinuous mode at primary side are converted to low frequency (400/60/50 Hz) waveforms at the output. This control strategy allows the converter to operate at high power density, as soft switching (ZCS/ZVS) is possible at both the turn-on and tur

Multilevel inverters have attracted wide interest in both the academic community and the industry for the past decades. Therefore, the investigation and development of modulation strategies in multilevel inverters emerges as a necessity for the industry and researchers.

This work investigates modifications to the existing digital sampling methods for pulse width modulation of power electronic amplifiers so that faster and more accurate control can be achieved. It proposes resampled PWM as a generalisation of the existing methods and presents simulations and experiments that demonstrate its superior performance. Power hardware in the loop experiments are also presented as a demonstration of an application which demands both high bandwidth and high amplifier power levels and which benefits from the improved controllable bandwidth of resampled PWM.

Abstract:

Power electronics have a significant role in modern electrical devices, for instance, hybrid electric vehicles. Power electronics are the technology in between the source and the load circuits and can convert the power from dc to ac or from dc to ac. There are also many types of dc-dc converters, like such as boost and buck converters, which exhibit switching ripple behavior. A boost converter increases the output voltage (with respect to the input voltage) and reduces the output current. A buck converter decreases the output voltage and increases the output current.

Control of a low voltage ac/dc/ac converter for high-speed induction machine drive applications has been investigated.

Indirect rotor-flux-oriented control and direct torque control are designed and compared for the control of an exemplary high-speed induction machine drive.

Abstract:

The emergence of silicon-carbide (SiC) devices has been a 'game changer' in the field of power electronics. With desirable material properties such as low-loss characteristics, high blocking voltage, and high junction temperature operation, they are expected to drastically increase the power density of power electronics systems. Recent state-of-the-art designs show the power density over 17 ; however, certain factors limit the power density to increase beyond this limit. In this dissertation, three key factors are selected to increase the power density of SiC-based grid-connected three-phase

Abstract:

The continuous conduction mode (CCM) boost, buck-boost and buck-boost derived pulse-width modulation dc-dc converters suffer from the large-signal control-to-output nonlinearity. Without feedback control, the large-signal control-to-output nonlinearity would lead to output overregulation and even damage the components. The control gain is defined as the ratio of output voltage to control signal. The small-signal control gain is defined as differentiating output voltage with respect to control signal. Feedback control helps to make the output trace the reference signal. A large-signal control

Abstract:

AC/DC adapters mostly employ two-stage topology: Power Factor Correction (PFC) pre-regulation stage followed by an isolated DC/DC converter stage. Low power AC/DC adapters require a small size to be competitive. Among their components, the bulk DC-link capacitor is one of the largest because it should keep the output voltage with low ripple. Also, the size of this capacitor is penalized due to the universal line voltage application. Synchronization through employing leading edge modulation for the first PFC stage and trailing edge modulation for the second DC/DC converter stage can significant

Abstract:

L’impact des stratégies Modulation de Largeur d'Impulsion (MLI) sur les sollicitations des condensateurs de découplage en entrée d’un onduleur triphasé est bien connu à l’heure actuelle au même titre que le comportement de la charge alimentée (facteur de puissance). On dispose à l’heure actuelle d’un large panel de techniques de modulation applicables en fonction des diverses contraintes d’environnement (stress des condensateurs mais aussi qualité des courants dans la charge ou pertes par commutation dans les semi-conducteurs). Toutefois, dans de nombreux contextes applicatifs, le bus continu

Abstract:

La problématique de recherche abordée dans ce mémoire de thèse découle de l’étude approfondie d’une association convertisseur-machine dédiée aux modes traction et recharge d’un véhicule électrique. Il s’agit d’un onduleur triphasé constitué de trois onduleurs monophasés connectés à une machine triphasée à phases indépendantes.Dans le chapitre II, une étude comparative entre deux solutions industrielles montre que l’architecture étudiée offre des caractéristiques compétitives notamment en termes de rendement global du convertisseur, performances mécaniques, et surface de silicium nécessaire.Par

Abstract:

<p>With an increasing number of transistors integrated on a single die, the need for global on-chip interconnectivity is growing. Long interconnects, in turn, have very large capacitances which consume a large share of a chip’s total power budget.</p><p>Power consumption can be lowered in several ways, mainly by reduction of switching activity, reduction of total capacitance and by using low voltage swing. In this project, the issue is addressed by proposing a new encoding based on Pulse Width Modulation (PWM). The implementation of this encoding will both lower the switching activity and decr

Abstract:

Experimental research on high-power converters, particularly in an academic environment, faces severe infrastructural constraints. Usually, power source and loads of required ratings are not available. Further, more importantly, the energy consumption is huge. One possibility is to establish an experimental research platform, comprising of a network of high-power converters, through which power is circulated and which draws only the losses from the mains. This work deals with the establishment of a circulating power test set-up, comprising of two line-side PWM converters, inclusive of contro
