Abstract: Recently, Power quality is one of major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. To improve the power quality, custom power devices are used. The device considered in this work is Dynamic Voltage Restorer. Thispresents modelling, analysis and simulation of a Dynamic Voltage Restorer (DVR) constructed in Simulink environment. Here, different supply voltage conditions are considered for linear loads. The major problems dealt here are voltage sag, voltage swell, and voltages unbalances. The role of DVR to compensate load voltage is investigated during the different supply conditions like voltage sag, voltage swell, and supply voltage unbalance. Therefore, it is a highly prospective branch of energy, which would play a significant role in the future.

Streszczenie:

Developments in automotive (particularly hybrid-electric vehicles), aerospace, and energy production industries have led to expanding research interest in integrated circuit (IC) design toward high-temperature applications. A high-voltage, high-temperature silicon-on-insulator (SOI) process allows for circuit design to expand into these extreme environment applications. Nearly all electronic devices require a reliable supply voltage capable of operating under various supply voltages and load currents. These supply voltages and load currents can be either DC or time-varying signals. In this work, a stable supply voltage for embedded circuits is generated on chip via a voltage regulator producing a stable 5-V output voltage. Although applications of this voltage regulator are not limited to gate driver circuits, this regulator has been developed to meet the demands of a gate driver IC. The voltage regulator must be able to provide reliable output voltage over an input range from 10 V to 30 V, a temperature range of −25°C to 200°C, and output loads from 0 mA to 200 mA. Additionally, low power stand-by operation is provided to help reduce heat generation resulting in lower operating junction temperature. The designed voltage regulator has been successfully tested from −50°C to 200°C while demonstrating an output voltage variation of less than 10 mV under the full range of input voltage. Additionally, line regulation tests from 10 V to 30 V show a 12-ppm/V supply sensitivity. Full temperature and input voltage range tests reveal that the no-load supply current draw is within 17 mA while still providing in excess of 200-mA load current upon demand. Modifications to the existing design or off-chip biasing can widen the range of attainable output voltages and drive capabilities.

Streszczenie:

A DC/DC voltage booster circuit is essential to design for the high-pressure (H.P.) injector driving circuit since the power supply voltages for various H.P. injectors are DC 60~90 V rather than DC 12~14V battery voltages. The DC 12~14V battery voltages have to be boosted up to the stable DC 60~90 V voltages supply for being able to drive various H.P. injectors. The new H.P. injector driving circuit consists of a voltage booster circuit and an originally designed three-stage power MOSFETs injector driving circuit to control the dc-link power supply voltage. The dynamic performance of a H.P. injector driven by the designed electrical driving circuit with the voltage booster are simulated and analyzed. The stability and electrical characteristics for the voltage booster under various injection pulse durations and engine speeds are investigated. The fuel injection quantities, supply voltages and injector driving currents of the H.P. injector fed by the new injector driving circuit is illustrated and analyzed in the paper. The experimental results show that this injector driving circuit with a newly designed voltage booster is capable of operating stably to drive the H.P. injector and obtain the accurate fuel injection quantities in the air-fuel ratio control of engines.

Streszczenie:

In this paper, a low-voltage low-dropout analog regulator (ALDO) based on a native n-channel MOS transistor is proposed. Application of the native transistor with the threshold voltage close to zero allows elimination of the charge pump in low-voltage regulators using the pass element in a common drain configuration. Such a native pass transistor configuration allows simplification of regulator design and improved performance, with supply voltages below 1 V, compared to commonly used regulators with p-channel MOS transistors. In the presented design of ALDO regulator in 180 nm CMOS X-FAB technology, an output voltage of 0.7 V was achieved with an output current of 10 mA and a supply voltage of 0.8 V. Simulation results show that despite the low supply voltage, output voltage spikes do not exceed 70 mV at the worst technology corner when output current transients from 100 µA to 10 mA. Under such conditions, stable operation and power supply rejection PSR = 35 dB were achieved with an output capacitance of 0–500 pF. The proposed regulator allows to push the limit of ALDO regulator applications to voltages below 1 V with only slight degradation of its performance.

Abstract. With the shrinking of the device dimensions, the power supply voltage value is continuously decreasing. Since the threshold voltage value does not decrease as much as the power supply and the drain source saturation voltage becomes an important fraction of the power supply, many amplifier architectures are no more suitable for modern processes. A transconductance amplifier based on current mirrors is analyzed highlighting the main challenges of a low-voltage analog design. Among the many proposed amplifier architectures, a topology based on current mirrors has been chosen as the most promising to operate with low voltages. Simulations with 90nm CMOS prove the feasibility of circuit operation with satisfactory performance at an operating power supply voltage as low as 0.6V.

Scaling supply voltage is an efficient approach to achieve low energy. Scaling supply voltage to sub-threshold region can reach minimum energy consumption but only suits for ultra-low operation frequencies. In order to attain more extensive application, scaling supply voltage to medium-voltage region is an attractive approach especially suiting for mid performances. This paper investigates performances of conventional SRAMs in near-threshold and super-threshold regions in terms of energy dissipation and max operating frequency. All circuits are simulated with HSPICE at PTM 45nm CMOS technology by varying supply voltages from 0.4V to 1.1V with 0.1V steps. The simulation results demonstrate that the conventional SRAMs operate on medium-voltage region can not only keep reasonable speed but also reduce greatly energy consumptions.

The paper describes major issues related to the design of a portable SiC-based DC supply developed for evaluation of a high-voltage Marx generator. This generator is developed to be a part of an electromagnetic cannon providing very high voltage and current pulses aiming at the destruction of electronics equipment in a specific area. The portable DC supply offers a very high voltage gain: input voltage is 24 V, while the generator requires supply voltages up to 50 kV. Thus, the system contains two stages designed on the basis of SiC power devices operating with frequencies up to 100 kHz. At first, the input voltage is boosted up to 400 V by a non-isolated double-boost converter, and then a resonant DC-DC converter with a special transformer elevates the voltage to the required level. In the paper, the main components of the laboratory setup are presented, and experimental results of the DC supply and whole system are also shown.

Lowering supply voltage of FinFET circuits is an effective way to achieve low power dissipations. In this paper, the super-threshold adiabatic FinFET circuits based on PAL-2N operating on medium strong inversion regions are addressed in terms of energy consumption and operating frequency. The supply voltage of the super-threshold circuits is much larger than the threshold voltage of the transistors, but it is lower than the normal standard supply voltage. The performance of a mode-10 FinFET PAL-2N counter is investigated with different source voltages ranging from 0.2V to 1.0V. All circuits are simulated with HSPICE at a PTM (Predictive Technology Model) 32nm FinFET technology. The simulation results show that the adiabatic FinFET circuits based on PAL-2N achieve the minimum EDP in the supply voltages of about 700mV - 800mV, the devices of which operate in medium strong inversion regions. The super-threshold adiabatic FinFET logic circuits can attain low energy consumption with favorable performance, since FinFET devices can provide better drive strength than bulk CMOS ones.

The provision of electricity has become a global necessity. In the developing world, residential electrification has become a tool for poverty alleviation. Unfortunately connecting residential customers to the grid, particularly in the low income communities, is more of a social task as the expected returns from the investment are unlikely to cover the costs to electrify and supply the communities. In such cases it is necessary to not over- or under-design a low voltage (LV) distribution network as this leads to unnecessary capital expenditure. The main source of uncertainty in designing LV residential distribution networks has been found to be the mode used to model the residential load. Residential electricity demand is a stochastic parameter dependant on the behaviour and occupancy patterns of household occupants. Traditionally the After Diversity Maximum Demand (ADMD), which is in essence and average value of load per household, was used to model load. However, using a singular value to describe the complex random nature of load is misleading. Probabilistic methods have been adopted to model residential load behaviour as these methods are better suited to representing the stochastic nature of the load. The Beta probability function was found to be the best representative function of residential load as its characteristics were reflective of the attributes of residential load. Studies on pre-existing LV networks in South Africa have found that these networks are operating outside of Quality of Suppy (QoS) regulation. The current QoS guideline of South Africa NRS 048-2 stipulates that 5% of measured supply voltage levels measured during a certain period are allowed to be outside the QoS compliance limits. This means that 95% QoS compliance of supply voltage levels is required for all LV networks. This QoS condition has not currently been worked into the design parameters. If a network is operating out of QoS guidelines a network upgrade is necessary. This research showed that the main source of the QoS violations of these networks was due to the risk levels used to calculate the expected voltage drops during the design stage of the networks. Typically, 10% risk is used for voltage drop calculations. This means that a best case of 90% compliance is expected which is outside the 95% compliance limit required by NRS 048- This study focused on two objectives. The first was to derive design parameters that are representative of residential load and can be used to design LV networks that comply with QoS specifications. The second was to define a means or develop a model for LV network designers to distinguish the parameters appropriate for a design, based on the customer class to be electrified. In this investigation new design parameters were derived that incorporate the 95% compliance limit of NRS 048-2 allowing LV networks built based on the new parameters, to operate within QoS limits. The parameters were derived using residential load data collected in South Africa since the early 1990's. An equation was also derived which allows countries with only ADMD data available to calculate QoS design parameters suitable for their situation.

This thesis presents techniques to implement analog-to-digital converters (ADCs) under an ultra-low-supply-voltage of 0.2 V to reduce the power consumption. The thesis proposes a dynamic bulk biasing circuit to adjust the PMOS bulk voltage to balance the NMOS and PMOS drain currents to guarantee functionality in the presence of process, voltage, and temperature variations. The dynamic bulk bias circuit is analyzed rigorously to show its functionality. This thesis also describes a new comparator suitable for a 0.2-V supply using ac-coupling, stacked input pairs, and voltage-boosted load capacitor. A 10-bit 5-kS/s successive-approximation-register (SAR) ADC in a 180-nm CMOS process with a supply voltage of 0.2 V demonstrates these ideas. The ADC exhibits a differential nonlinearity (DNL) and integral nonlinearity (INL) within +0.42/-0.45 and +0.62/-0.67 LSB, respectively. The measured SFDR and SNDR at 5 kS/s with a Nyquist-frequency input are 65.9 dB and 52.1 dB, respectively. The entire ADC and dynamic bulk biasing circuitry consume 22 nW including leakage power to yield a figure-of-meirt (FoM) of 8.8 fJ/conv.-step. Measurements of multiple chips show the proposed dynamic bulk biasing fully recovers the ADC performance when the supply voltage is varied. The nW power consumption makes the design well suited for wireless sensor node and energy harvester applications.

A switching power supply to drive magnetrons for microwave heating has been designed, prototyped and tested. The magnetron has an rf power output of 6000 watts and requires a DC voltage of 7200 volts at a current of approximately 1.1 amps for a power input to the magnetron of 8000 watts. Six magnetrons are to be connected per railway tanker for heating the tankers at a railway terminus. The power supply has been designed for small size, efficiency and reliability. Current technology has been used. Insulated Gate Bipolar Transistors (IGBT) and power MOSFETs, both of moderately high current and voltage ratings, have been used at 25 kHz and 50 kHz switching frequencies respectively. MOSFETs of 20 amps and 500 volts and IGBT's of 40 amps and 600 volts ratings have been used. Ferrites for use at high switching frequencies have been used for transformers and iron powder material has been used for energy storage inductors. High quality insulating materials have been used to achieve the high voltage insulation requirements. Kapton, PTFE, mylar and nylon have been used where appropriate. Special features of the power supply include the power factor correction first stage, the use of the higher than normal leakage inductance of the power converter second stage transformer to make a resonant converter and the ripple cancelling effect of the series connection of the units on each phase. The power factor correction meets I EC 555 and AS2279 standards for harmonic content on the power supply source. The resonant converter yields zero load current switching of the converter transistors. The output 100 Hz ripple on the 7200 volt supply is negligible because of the series connection of the three outputs.

In this thesis, algorithms are proposed to improve electricity distribution network supply restoration. The practical implementation of such algorithms relies on the presence of fully automated switches located at a certain number of network substations. The algorithm has the capability to restore a maximum number of customers if an outage occurs on any section of the test network. Since a very high cost is usually involved in the implementation of the fully automated system, a second algorithm was introduced with the aim of reducing the number and location of required switches. Discrete Particle Swarm Optimisation (DPSO) was employed to identify optimal placement of a limited number of remotely operable protective devices as well as the optimal sequence of reconfiguration and restoration of the supply. The reliability of the network was determined by calculating the number of possible post-outage restored customers, considering both upstream and downstream restorations. In the selection of optimal switching sequences, network voltage and current constraints were also considered to ensure that the identified restoration was viable. Further, the proposed algorithm considered the failure rate on each section of the network in arriving at the proposed optimal locations of switches. The developed DPSO-based algorithm and Brute Force is described and applied to real 11kV urban, semi-urban and rural distribution networks each with a different number of feeders and substations. These proposed algorithms have the capability to search for an unlimited number and locations of switches pairs or clusters for all networks (urban, semi-urban and rural) with optimal locations and number of Remotely Operable Switch Pairs (ROS). It was demonstrated that less than half of fully automated switches are needed to restore more than 95% of customers for each case study network. A significant reduction in investment cost of protective devices could be achieved by applying the proposed algorithm and at the same time improving and optimising the reliability of 11kV distribution networks.

Streszczenie:

Demands for delivering high instantaneous power in a compressed form (pulse shape) have widely increased during recent decades. The flexible shapes with variable pulse specifications offered by pulsed power have made it a practical and effective supply method for an extensive range of applications. In particular, the release of basic subatomic particles (i.e. electron, proton and neutron) in an atom (ionization process) and the synthesizing of molecules to form ions or other molecules are among those reactions that necessitate large amount of instantaneous power. In addition to the decomposition process, there have recently been requests for pulsed power in other areas such as in the combination of molecules (i.e. fusion, material joining), gessoes radiations (i.e. electron beams, laser, and radar), explosions (i.e. concrete recycling), wastewater, exhausted gas, and material surface treatments. These pulses are widely employed in the silent discharge process in all types of materials (including gas, fluid and solid); in some cases, to form the plasma and consequently accelerate the associated process. Due to this fast growing demand for pulsed power in industrial and environmental applications, the exigency of having more efficient and flexible pulse modulators is now receiving greater consideration. Sensitive applications, such as plasma fusion and laser guns also require more precisely produced repetitive pulses with a higher quality. Many research studies are being conducted in different areas that need a flexible pulse modulator to vary pulse features to investigate the influence of these variations on the application. In addition, there is the need to prevent the waste of a considerable amount of energy caused by the arc phenomena that frequently occur after the plasma process. The control over power flow during the supply process is a critical skill that enables the pulse supply to halt the supply process at any stage. Different pulse modulators which utilise different accumulation techniques including Marx Generators (MG), Magnetic Pulse Compressors (MPC), Pulse Forming Networks (PFN) and Multistage Blumlein Lines (MBL) are currently employed to supply a wide range of applications. Gas/Magnetic switching technologies (such as spark gap and hydrogen thyratron) have conventionally been used as switching devices in pulse modulator structures because of their high voltage ratings and considerably low rising times. However, they also suffer from serious drawbacks such as, their low efficiency, reliability and repetition rate, and also their short life span. Being bulky, heavy and expensive are the other disadvantages associated with these devices. Recently developed solid-state switching technology is an appropriate substitution for these switching devices due to the benefits they bring to the pulse supplies. Besides being compact, efficient, reasonable and reliable, and having a long life span, their high frequency switching skill allows repetitive operation of pulsed power supply. The main concerns in using solid-state transistors are the voltage rating and the rising time of available switches that, in some cases, cannot satisfy the application’s requirements. However, there are several power electronics configurations and techniques that make solid-state utilisation feasible for high voltage pulse generation. Therefore, the design and development of novel methods and topologies with higher efficiency and flexibility for pulsed power generators have been considered as the main scope of this research work. This aim is pursued through several innovative proposals that can be classified under the following two principal objectives. • To innovate and develop novel solid-state based topologies for pulsed power generation • To improve available technologies that have the potential to accommodate solid-state technology by revising, reconfiguring and adjusting their structure and control algorithms. The quest to distinguish novel topologies for a proper pulsed power production was begun with a deep and through review of conventional pulse generators and useful power electronics topologies. As a result of this study, it appears that efficiency and flexibility are the most significant demands of plasma applications that have not been met by state-of-the-art methods. Many solid-state based configurations were considered and simulated in order to evaluate their potential to be utilised in the pulsed power area. Parts of this literature review are documented in Chapter 1 of this thesis. Current source topologies demonstrate valuable advantages in supplying the loads with capacitive characteristics such as plasma applications. To investigate the influence of switching transients associated with solid-state devices on rise time of pulses, simulation based studies have been undertaken. A variable current source is considered to pump different current levels to a capacitive load, and it was evident that dissimilar dv/dts are produced at the output. Thereby, transient effects on pulse rising time are denied regarding the evidence acquired from this examination. A detailed report of this study is given in Chapter 6 of this thesis. This study inspired the design of a solid-state based topology that take advantage of both current and voltage sources. A series of switch-resistor-capacitor units at the output splits the produced voltage to lower levels, so it can be shared by the switches. A smart but complicated switching strategy is also designed to discharge the residual energy after each supply cycle. To prevent reverse power flow and to reduce the complexity of the control algorithm in this system, the resistors in common paths of units are substituted with diode rectifiers (switch-diode-capacitor). This modification not only gives the feasibility of stopping the load supply process to the supplier at any stage (and consequently saving energy), but also enables the converter to operate in a two-stroke mode with asymmetrical capacitors. The components’ determination and exchanging energy calculations are accomplished with respect to application specifications and demands. Both topologies were simply modelled and simulation studies have been carried out with the simplified models. Experimental assessments were also executed on implemented hardware and the approaches verified the initial analysis. Reports on details of both converters are thoroughly discussed in Chapters 2 and 3 of the thesis. Conventional MGs have been recently modified to use solid-state transistors (i.e. Insulated gate bipolar transistors) instead of magnetic/gas switching devices. Resistive insulators previously used in their structures are substituted by diode rectifiers to adjust MGs for a proper voltage sharing. However, despite utilizing solid-state technology in MGs configurations, further design and control amendments can still be made to achieve an improved performance with fewer components. Considering a number of charging techniques, resonant phenomenon is adopted in a proposal to charge the capacitors. In addition to charging the capacitors at twice the input voltage, triggering switches at the moment at which the conducted current through switches is zero significantly reduces the switching losses. Another configuration is also introduced in this research for Marx topology based on commutation circuits that use a current source to charge the capacitors. According to this design, diode-capacitor units, each including two Marx stages, are connected in cascade through solid-state devices and aggregate the voltages across the capacitors to produce a high voltage pulse. The polarity of voltage across one capacitor in each unit is reversed in an intermediate mode by connecting the commutation circuit to the capacitor. The insulation of input side from load side is provided in this topology by disconnecting the load from the current source during the supply process. Furthermore, the number of required fast switching devices in both designs is reduced to half of the number used in a conventional MG; they are replaced with slower switches (such as Thyristors) that need simpler driving modules. In addition, the contributing switches in discharging paths are decreased to half; this decrease leads to a reduction in conduction losses. Associated models are simulated, and hardware tests are performed to verify the validity of proposed topologies. Chapters 4, 5 and 7 of the thesis present all relevant analysis and approaches according to these topologies.

Streszczenie:

The economics of high voltage direct current for long-distance transmission of electrical energy have been reported as very attractive, to the extent that several projects are in the making. Several reasons other than the savings in transmission costs, for example the exchange of peak power between time zones and seasonal zones, would permit utilities to save on plant investment for generating capacity while maintaining a high level of service. This report summarizes work on the initial phase of a study to determine the effects of high-voltage direct-current (H.V.D.C.) electric transmission lines on buried pipeline systems. Pipeline Research Council International, Inc. initiated this work in response to an anticipated threat posed by the Pacific Northwest-Southwest Intertie H.V.D.C. system now being designed (and other possible H.V.D.C. lines in the future) because of the announced plans to pass direct current through the earth. The objectives of the overall program are:(1) To determine the nature and magnitude of problems that will be created by the earth current from H.V.D.C. systems, and(2) To devise means of protecting pipelines from the effects of such currents. A computer program was written based on a mathematical model of a buried pipeline in the environment created by an H.V.D.C. system. Excellent agreement was obtained between computed soil potential gradients and measurements obtained during a field test of H.V.D.C. in Oregon. Reasonably good agreement was also obtained between measured pipe-to-soil potentials on the Pacific Lighting Gas Supply Company pipeline near Camino, California, and computed values during a field test of H.V.D.C. power transmission.
