Abstract:
This paper introduces a reference-free, scalable, and energy-efficient dynamic voltage scaler (DVS) that can be reconfigured for multiple outputs. The proposed DVS employs a novel swapping switched-capacitor (SSC) technique, which can generate target output voltages with higher resolution and smaller ripple voltages than the conventional voltage scalers based on switched-capacitors. The proposed DVS consists of a cascaded 2:1 converter based on swapping capacitors, which is essential to achieve both very small voltage ripple and fine-grain conversion ratios. One of the serious drawbacks of the conventional voltage scalers is the need for external reference voltages to maintain the target output voltage. The proposed SSC; however, eliminates the needs for any reference voltages. This significant benefit is achieved by the self-charging ability of the SSC, which can recharge all its capacitors to the configured voltage by simply swapping the two capacitors in each stage. The proposed SSC-DVS was designed with a resolution of 16 output levels and implemented using a 130 nm CMOS (Complementary Metal Oxide semiconductor) process. We conducted measured results and post-layout simulations with an input voltage of 1.5 V to produce an output voltage range of 0.085–1.4 V, which demonstrated a power efficiency of 85% for a load current of 550 µA with a voltage ripple of as low as 2.656 mV for a 2 KΩ resistor load.

Abstract:
Introduction. Nowadays, power quality issues are of considerable interest to both utilities and end users as they cause significant financial losses to the industrial customers. Due to this, power quality assurance in power distribution systems is very important, when considering commercial and industrial applications. Problem Statement. Unfortunately, sudden faults such as sag, transients, harmonics distortion and notching in the power system create disturbances and affect the load voltages. Out of these, voltage sag and harmonics seriously affect sensitive devices. Harmonics in the power system cause increased heating of equipment and conductors, misfires in variable speed drives, and torque pulsations in motors. Harmonics reduction is considered desirable. Methodology. This paper presents an efficient and robust solution to this problem by using dynamic voltage restorer in series with distribution system. Dynamic voltage restorer is economical and effective solution for protecting sensitive loads from harmonics and sag. Control strategy is adopted with dynamic voltage restorer topology and the performance with the proposed controller is analyzed. Novelty. In this research work modelling, analysis and simulation of dynamic voltage restorer with proportional integral controller and dynamic voltage restorer with sliding-mode controller at optimal voltage is used to improve the dynamic voltage restorer performance by reducing total harmonic distortion. Results. The simulation is performed in MATLAB / Simulink software package and comparative analysis of dynamic voltage restorer with different controllers for distribution system is presented. The proposed scheme successfully reduced percentage total harmonics distortion and voltage sag using dynamic voltage restorer with sliding mode controller at optimal voltage which is found to be 0.38 %.

Abstract:
Quality of the output power delivered from the utilities has become a major concern of the modern industries for the last decade. These power quality associated problems are voltage sag, surge, flicker, voltage imbalance, interruptions and harmonic problems. These power quality issues may cause problems to the industries ranging from malfunctioning of equipments to complete plant shut downs. Those power quality problems affect the microprocessor based loads, process equipments, sensitive electric components which are highly sensitive to voltage level fluctuations. It has been identified that power quality can be degraded both due to utility side abnormalities as well as the customer side abnormalities. To overcome the problems caused by customer side abnormalities so called custom power devices are connected closer to the load end. One such reliable customer power device used to address the voltage sag, swell problem is the Dynamic Voltage Restorer (DVR). It is a series connected custom power device, which is considered to be a cost effective alternative when compared with other commercially available voltage sag compensation devices. The main function of the DVR is to monitor the load voltage waveform constantly and if any sag or surge occurs, the balance (or excess) voltage is injected to (or absorbed from) the load voltage. To achieve the above functionality a reference voltage waveform has to be created which is similar in magnitude and phase angle to that of the supply voltage. Thereby during any abnormality of the voltage waveform it can be detected by comparing the reference and the actual voltage waveforms. A new control technique to detect and compensate for the single phase voltage sags is designed in this project. The simulation was checked in the EMTDC/PSCAD simulation software and has shown reliable results.

Abstract:
<p>Embedded computing systems in portable devices need to be energy efficient, yet they have to deliver adequate performance to the often computationally expensive applications. Dynamic voltage scaling is a technique that offers a speed versus power trade-off, allowing the application to achieve considerable energy savings and, at the same time, to meet the imposed time constraints.</p><p>In this thesis, we explore the possibility of using optimal voltage scaling algorithms based on nonlinear programming at the system level, for a complex multiprocessor scheduling problem. We present an optimization approach to the modeled nonlinear programming formulation of the continuous voltage selection problem excluding the consideration of transition overheads. Our approach achieves the same optimal results as the previous work using the same model, but due to its speed, can be efficiently used for design space exploration. We validate our results using numerous automatically generated benchmarks.</p>

Abstract:
CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO<br>O problema tratado nesta dissertação é a relação oposta entre a tensão de excitação de geradores e compensadores síncronos e a tensão controlada, quando o sistema de transmissão da área encontra-se muito carregado. Neste caso, a capacidade nominal de um gerador / compensador não seria útil para manter a tensão controlada. Devido à relação oposta, uma maior excitação da máquina iria abaixar a tensão controlada. O controle automático iria continuar agindo, abaixando ainda mais a tensão. Este mecanismo pode levar o sistema ao colapso e foi verificado em ponto de operação real do sistema brasileiro. Esse fenômeno ocorre quando a injeção de potência na rede de transmissão ou distribuição é elevada. Com o advento da geração distribuída, co-geração e produtores independentes, usualmente conectados à rede existente em níveis de tensão mais baixas, têm-se observado ocorrências do fenômeno. O objetivo do trabalho é então entender melhor as situações operativas reais que levam à ocorrência do fenômeno, principalmente quando existem vários equipamentos de controle de tensão ao redor do gerador em análise. A abordagem do problema baseou-se na verificação do comportamento do gerador / compensador como dispositivo de controle de tensão, no domínio do tempo e em regime permanente. Avaliaram-se as ações de controle do mesmo a partir de sete tipos de análise distintas para pontos de operação na região normal e anormal da curva SV. A real existência do fenômeno foi comprovada através de algumas destas análises. Porém, conclui-se que nem todas as formas de análise no domínio do tempo fazem uma avaliação completa do fenômeno. Dentre essas, estão a análise dinâmica agregada e a análise dinâmica agregada sob influência dos equipamentos de controle de tensão, que para pontos de operação na região anormal da curva SV não responderam em concordância com os outros tipos de análise.<br>The problem addressed in this research is the opposite relationship between the , synchronous generator / compensator excitation voltage and the controlled voltage when nearby network is heavily loaded. In this situation, the nominal capacity of a generator / compensator would not keep the voltage controlled. Due to the opposite relationship, the higher the excitation voltage the lower is the controlled voltage. So, the automatic control would continue acting lowering the voltage. This mechanism, verified in a real operational point of the Brazilian Electric System, can lead the system to collapse. This phenomenon occurs when the power injection into the network is high. It is prone to occur in the new scenario of distributed generation connected to already existing low voltage networks. The objective of this work is to understand the actual operative situations that lead to the occurrence of the phenomenon, mainly when there are several voltage control devices nearby the generator. The analysis of the problem was based on the verification of the generator behaviour as a voltage control device, in time domain simulation and in steady state. The control actions were evaluated from seven different ways for operating points in the normal and the abnormal region of the SV curve. The actual existence of the phenomenon was proven through some of these analyses. However, some of the time domain simulations did not evaluated the phenomenon completely. Among them, the aggregated dynamic analysis and the aggregated dynamic analysis under influence of other voltage control devices have not got the expected responses for the abnormal region of the SV curve, in comparison with other analysis.

Abstract:
Increased government funding and incentives in recent years has led to an increase in the number of grid-tied renewable energy sources as their economic benefits become more renowned. Unfortunately, the outputs of these renewable resources are often highly variable, resulting in undesirable voltage disruptions that are harmful to sensitive loads. In addition to the energy variability of renewable energy sources, random voltage sags, swells and disruptions are already a major issue in power systems. Recent advances in power electronic devices have provided a platform for new solutions to the voltage support problem in power systems. One promising solution is the Dynamic Voltage Regulator (DVR), a series compensating device used to protect a sensitive load that is connected downstream from voltage sag or swell. For this thesis, the design, modeling, and analysis of a DVR system were performed using PSCAD software. Results from simulation demonstrate the DVR’s effectiveness in protecting a sensitive load from load and source side voltage disturbances as well as regulate the load bus voltage to its rated value.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO<br>O tema abordado neste trabalho é a observação e análise, em regime permanente e dinâmico, da ocorrência de um fenômeno que já foi observado em condições reais de operação do sistema elétrico brasileiro, que é a relação oposta à usual entre a grandeza controlada e a grandeza controladora. Nestes caso, mesmo que haja margem de recursos para manter a tensão controlada, ela não é útil. Por exemplo, uma diminuição na relação de transformação num transformador de tapes variáveis, com intuito de aumentar a tensão controlada acaba por reduzí-la, até que os limites de troca de tapes sejam atingidos ou o sistema entre em colapso. Para demonstrar a existência do problema, foram executadas simulações, em regime permanente e dinâmico, e verificado o efeito do controle de tensão por um transformador com tapes variáveis e por compensadores estáticos de potência reativa, situações corriqueiras de um sistema de potência. Foram demonstradas situações em que foi possível verificar a mudança da região de operação. Para a análise em regime permanente foi utilizado um algoritmo de fluxo de carga, e para a análise dinâmica, uma simulação no domínio do tempo. Nas simulações envolvendo transformadores de tapes variáveis, foi possível verificar a existência o efeito reverso da ação de controle de tensão nas análises estática e dinâmica. Nas simulações utilizando o compensador estático de potência reativa houve divergência entre os resultados das duas análises.<br>This work presents the observation and analysis, in steady state and dynamic performance, of the phenomenon already observed in real operation conditions of the Brazilian Electric System, which is the opposite relationship between the controlled value and the target value. In this case, even if the resources have margin to keep the voltage controlled, this is not useful. For example, the reduction in the turn ratio on load tap changer transformer, with the aim of increase in the controlled voltage, result in its reduction, until the tap changer limit is reached or the system is led to the collapse. To demonstrate the existence of this problem, steady state and dynamic performance simulations were done, and the voltage control effect by on load tap changer transformer and static var compensator , current situations in a power system. Several situations where is possible verify the operation region changing was demonstrated. For steady state analysis was used a load flow algorithm and, for the dynamic analysis, a time domain simulation. In the simulations with on load tap changer transformer, it was possible to verify the existence of the reverse effect of the voltage control action in the static and dynamic analysis. In the simulations using static var compensator, a divergence was found between the results in the two analyses.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2008.<br>Includes bibliographical references (leaves 73-78).<br>With the continuous scaling down of transistor feature sizes, the semiconductor industry faces new challenges. One of these challenges is the incessant increase of power consumption in integrated circuits. This problem has motivated the industry and academia to pay significant attention to low-power circuit design for the past two decades. Operating digital circuits at lower voltage levels was shown to increase energy efficiency and lower power consumption. Being an integral part of the digital systems, Static Random Access Memories (SRAMs), dominate the power consumption and area of modern integrated circuits. Consequently, designing low-power high density SRAMs operational at low voltage levels is an important research problem. This thesis focuses on and makes several contributions to low-power SRAM design. The trade-offs and potential overheads associated with designing SRAMs for a very large voltage range are analyzed. An 8T SRAM cell is designed and optimized for both sub-threshold and above-threshold operation. Hardware reconfigurability is proposed as a solution to power and area overheads due to peripheral assist circuitry which are necessary for low voltage operation. A 64kbit SRAM has been designed in 65nm CMOS process and the fabricated chip has been tested, demonstrating operation at power supply levels from 0.25V to 1.2V. This is the largest operating voltage range reported in 65nm semiconductor technology node. Additionally, another low voltage SRAM has been designed for the on-chip caches of a low-power H.264 video decoder. Power and performance models of the memories have been developed along with a configurable interface circuit. This custom memory implemented with the low-power architecture of the decoder provides nearly 10X power savings.<br>by Mahmut E. Sinangil.<br>S.M.

Abstract:
Abstract This work deals with the voltage response of parametric resonance of electrostatically actuated microelectromechanical (MEMS) circular plates under hard excitations. Method of Multiple Scales (MMS) and Reduced Order Model (ROM) method using two modes of vibration are used to predict the voltage-amplitude response of the MEMS circular plates. ROM is solved using AUTO 07p, a software package for continuation and bifurcation. MMS used in this paper has one term in the electrostatic force being considered significant. This is the way MMS is used to model hard excitations. MMS shows results similar to those of ROM at lower amplitudes and lower voltages. The differences between the two methods, MMS and ROM, are significant in high amplitudes for all voltages, and the differences are significant in all amplitudes for larger voltages. Significant differences can be noted in the effect of different parameters such as the detuning frequency and damping on the voltage response. ROM AUTO 07p is calibrated using ROM time responses in which the ROM is solved using the solver ode15s in Matlab.

Abstract:
This paper deals with electrostatically actuated microelectromechanical (MEMS) cantilever resonators under soft AC double actuation. The cantilever is between two parallel ground plates. The two AC frequencies are one near half natural frequency, and the other near natural frequency. There is a phase difference between the two voltages. The system undergoes a simultaneous resonance. The voltage-amplitude response is investigated. The effects of the second voltage, phase difference between voltages, and frequency on the response are reported. The method of multiple scales is used in this paper.

Full text
Abstract:
This work investigates the voltage response of superharmonic resonance of second order of electrostatically actuated Micro-Electro-Mechanical Systems (MEMS) resonator cantilevers. The results of this work can be used for mass sensors design. The MEMS device consists of MEMS resonator cantilever over a parallel ground plate (electrode) under Alternating Current (AC) voltage. The AC voltage is of frequency near one fourth of the natural frequency of the resonator which leads to the superharmonic resonance of second order. The AC voltage produces an electrostatic force in the category of hard excitations, i.e. for small voltages the resonance is not present while for large voltages resonance occurs and bifurcation points are born. The forces acting on the resonator are electrostatic and damping. The damping force is assumed linear. The Casimir effect and van der Waals effect are negligible for a gap, i.e. the distance between the undeformed resonator and the ground plate, greater than one micrometer and 50 nanometers, respectively, which is the case in this research. The dimensional equation of motion is nondimensionalized by choosing the gap as reference length for deflections, the length of the resonator for the axial coordinate, and reference time based on the characteristics of the structure. The resulting dimensionless equation includes dimensionless parameters (coefficients) such as voltage parameter and damping parameter very important in characterizing the voltage-amplitude response of the structure. The Method of Multiple Scales (MMS) is used to find a solution of the differential equation of motion. MMS transforms the nonlinear partial differential equation of motion into two simpler problems, namely zero-order and first-order. In this work, since the structure is under hard excitations the electrostatic force must be in the zero-order problem. The assumption made in this investigation is that the dimensionless amplitudes are under 0.4 of the gap, and therefore all the terms in the Taylor expansion of the electrostatic force proportional to the deflection or its powers are small enough to be in the first-order problem. This way the zero-order problem solution includes the mode of vibration of the structure, i.e. natural frequency and mode shape, resulting from the homogeneous differential equation, as well as particular solutions due to the nonhomogeneous terms. This solution is then used in the first-order problem to find the voltage-amplitude response of the structure. The influences of frequency and damping on the response are investigated. This work opens the door of using smaller AC frequencies for MEMS resonator sensors.

Abstract:
Abstract This work studies the estimation of internal states and voltages in a battery pack composed by lithium-ion cells subject to limited voltage and temperature measurements. A reduced-order electrochemical model for each cell is used. The considered cells are heterogeneous. They are electrically interconnected in series and thermally coupled. The resulting model is linearized and reformulated as a descriptor system. Such a model provides a unified modeling framework accounting for both battery cell dynamics and algebraic states arising from standard Kirchhoff’s laws. An observability study is exploited to design an observable descriptor system that requires the measurement of the surface temperature of one cell together with the total voltage. We resort to Lyapunov theory and the algebraic relationship between the descriptor system states and the measurements to derive a state observer that meets the following conditions. The error system is input-to-state stable and the effect of cell-to-cell variations on a specified performance variable is minimized. The state observer is obtained by solving a set of LMIs. The proposed scheme is able to estimate the state of each individual cell, including state of charge and inner temperature, as well as the unmeasured voltages. The effectiveness of the approach is tested in simulation.

Abstract:
Design objectives in capacitive type radio frequency micro electro mechanical switches (RF-MEMS) are to reduce actuation voltages and to obtain low insertion losses with high isolation. In this study, we report design, modeling and simulation of three new structural configurations using ANSYS to obtain the optimum geometry; further high frequency simulations are performed using HFSS to obtain low insertion losses and high isolation. The designed switches require only 3.9 to 5 V as pull-in voltage for actuation. The mechanical resonant frequency and quality factor are in the range of 6.5 to 8.7 kHz and 1.1 to 1.2, respectively. Switching times for all the designs are 32 to 38 μs at their respective pull-in voltages. Two of the switch designs have insertion loss of less than 0.25 to 0.8 dB at 60 and 50 GHz, and isolation greater than 58 dB for all three designs.

Abstract:
Currently, to evaluate the dynamic characteristics of objects, quite a large number of devices are used in the form of chronographs, which consist of various optical, thermal and laser sensors. Among the problems of these devices, the following can be distinguished: the lack of recording of the received data; the inaccessibility of taking into account the trajectory of the object flying in the sensor area, as well as taking into consideration the trajectory of the object during the approach to the device frame. The signal received from the infrared sensors is recorded in a separate document in txt format, in the form of a table. When you turn to the document, data is read from the current position of the input data stream in the specified list by an argument in accordance with the given condition. As a result of reading the data, it forms an array that includes N number of columns. The array is constructed in a such way that the first column includes time values, and columns 2...N- the value of voltage . The algorithm uses cycles that perform the function of deleting array rows where there is a fact of exceeding the threshold value in more than two columns, as well as rows where the threshold level was not exceeded. The modified array is converted into two new arrays, each of which includes data from different sensor frames. An array with the coordinates of the centers of the sensor operation zones was created to apply the Pythagorean theorem in three-dimensional space, which is necessary for calculating the exact distance between the zones. The time is determined by the difference in the response of the first and second sensor frames. Knowing the path and time, we are able to calculate the exact speed of the object. For visualization, the oscillograms of each sensor channel were displayed, and a chronograph model was created. The chronograph model highlights in purple the area where the threshold has been exceeded.

Abstract:
Children work throughout the Lake Volta fisheries value chain. It is commonly assumed most have been trafficked. Research and advocacy has focused on dangers to young boys harvesting fish, and poverty as a driver, precluding attention to harms experienced by non-trafficked children, girls’ experiences and work-education dynamics. More work is needed on the proportions of children who fish and perform harmful work; structural, ecological and historical contexts; young people’s agency in pursuing fishing work; and why attention to trafficking dominates.

Abstract:
Energy from pavements can be harvested in multiple ways to produce clean energy. One of the techniques is electromagnetic energy harvesting, in which mechanical energy from vehicles is captured in the form of input displacement to produce electricity. In this study, a rack-and-pinion electromagnetic energy harvester proposed in the literature as a speed bump is optimized for highway-speed vehicles. A displacement transfer plate is also proposed, with a minimum depth of embedment in the pavement to carry input displacements from passing vehicles and excite the energy harvester. The energy harvester was designed, and kinematic modeling was carried out to establish power–output relations as a function of rack velocity. Sensitivity analysis of various parameters indicated that, for high-speed applications where rack velocities are relatively high, small input excitations could be harnessed to achieve the rated revolutions per minute (RPM) of the generator. A set of laboratory tests was conducted to validate the kinematic model, and a good correlation was observed between measured and predicted voltages. Dynamic modeling of the plate was done for both recovery and compression to obtain the plate and rack velocities. Using Monte Carlo simulation, the plate was designed for a class-9 truck with wide-base tires moving at 128 km/h. Design and layout of the energy harvester with a displacement transfer plate was proposed for field validation. The energy harvester with the displacement plate could be integrated with transverse rumble strips in construction zones and near diversions. Hence, it could be used as a standalone system to power roadside applications such as safety signs, road lights, speed cameras, and vehicle-to-infrastructure (V2I) systems.

Abstract:
This paper presents a comprehensive evaluation of the performance of an interior permanent magnet (IPM) traction motor drive, and analyses the impact of different modulation techniques. The most widely used modulation methods in traction motor drives are Space vector modulation (SVPWM), over-modulation, and six-step modulation have been implemented. A two-dimensional electromagnetic finite element model of the motor is co-simulated with a dynamic model of a field-oriented control (FOC) circuit. For accurate tuning of the current controllers, extended complex vector synchronous frame current regulators are employed. The DC-link voltage utilization, harmonics in the output waveforms, torque ripple, iron losses, and AC copper losses are calculated and compared with sinusoidal excitation. Overall, it is concluded that the selection of modulation technique is related to the operating condition and motor speed, and a smooth transition between different modulation techniques is essential to achieve a better performance.
