Streszczenie:
Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.

Streszczenie:
The advent of CubeSats has provided a platform for relatively low-budget programmes to realise space missions. In South Africa, Stellenbosch University and the Cape Peninsula University of Technology have impressive space programmes and have been involved in numerous successful satellite launches. A number of CubeSat projects are currently in progress and commercial-grade Attitude Determination and Control Systems (ADCS), and communications modules, are being developed by the respective universities. The development of a CubeSat-compatible Electrical Power System remains absent, and would be beneficial to future satellite activity here in South Africa. In this thesis, some fundamental aspects of electronic design for space applications is looked at, including but not limited to radiation effects on MOSFET devices; this poses one of the greatest challenges to space-based power systems. To this extent, the different radiation-induced effects and their implications are looked at, and mitigation strategies are discussed. A review of current commercial modules is performed and their design and performance evaluated. A few shortcomings of current systems are noted and corresponding design changes are suggested; in some instances these changes add complexity, but they are shown to introduce appreciable system reliability. A single Li-Ion cell configuration is proposed that uses a 3.7 V nominal bus voltage. Individual battery charge regulation introduces minor inefficiencies, but allows isolation of cells from the pack in the case of cell failure or degradation. A further advantage is the possibility for multiple energy storage media on the same power bus, allowing for EPS-related technology demonstrations, with an assurance of minimum system capabilities. The design of each subsystem is discussed and its respective failure modes identified. A limited number of single points of failure are noted and the mitigation strategies taken are discussed. An initial hardware prototype is developed that is used to test and characterise system performance. Although a few minor modifications are needed, the overall system is shown to function as designed and the concepts used are proven.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.
Includes bibliographical references (p. 321-323).
This thesis presents the modeling, design, and characterization of microfabricated, surface-wound, permanent-magnet (PM) generators, and their power electronics, for use in Watt-level Power MEMS applications such as a microscale gas turbine engine. The generators are three-phase, axial-flux, synchronous machines, comprising a rotor with an annular PM and ferromagnetic core, and a stator with multi-turn surface windings on a soft magnetic substrate. The fabrication of the PM generators, as well as the development of their high-speed spinning rotor test stand, was carried out by collaborators at the Georgia Institute of Technology. The machines are modeled by analytically solving 2D magneto-quasistatic Maxwell's Equations as a function of radius and then integrating the field solutions over the radial span of the machine to determine the open-circuit voltage, torque and losses in the stator core. The model provides a computationally fast method to determine power and efficiency of an axial-air-gap PM machine as a function of geometry, speed and material properties. Both passive and active power electronics have been built and tested. The passive power electronics consist of a three-phase transformer and diode bridge rectifier.
(cont.) The active power electronics consist of a switch-mode rectifier based on the boost semi-bridge topology which is used to convert the unregulated AC generator voltages to a regulated 12 V DC without the need for rotor position/speed or stator terminal current/voltage sensing. At the rotational speed of 300,000 rpm, one generator converts 16.2 W of mechanical power to electrical power. Coupled to the transformer and diode bridge rectifier, it delivers 8 W DC to a resistive load. This is the highest output power ever delivered by a microscale electric generator to date. The corresponding power and current densities of 57.8 MW/m3 and 6x 108 A/m2, respectively, are much higher than those of a macroscale electric generator. At the rotational speed of 300,000 rpm, the generator and switch-mode rectifier delivered 5.5 W DC to a resistive load at a power density three times that of the passive electronics. This Watt-scale electrical power generation demonstrates the viability of scaled PM machines and power electronics for practical Power MEMS applications.

Streszczenie:
The research work presented in this thesis is concerned with the modelling of this new generation of power electronics controllers with a view to conduct comprehensive power systems harmonic analyses. An issue of paramount importance in this research is the representation of the self-commutated valves used by the controllers addressed in this work. Such a representation is based on switching functions that enable the realization of flexible and comprehensive harmonic models. Modularity is another key issue of great importance in this research, and the model of the voltage source converter is used as the basic building block with which to assemble harmonic models of actual power systems controllers. In this research the complex Fourier series in the form of operational matrices was used to derive the harmonic models. Also, a novel methodology is presented in this thesis for conducting transient analysis of electric networks containing non-linearities and power electronic components. The methodology is termed the extended harmonic domain. This method is based on the use of time-dependent Fourier series, operational matrices, state-space representation and averaging methods. With this method, state-space equations for linear circuit, non-linear circuits, and power electronics controllers models are obtained. The state variables are the harmonic coefficients of x(t) instead of x(t) itself. The solution of the state-space equations gives the dynamic response of the harmonic coefficients of x(t). Moreover, a new harmonic power flow methodology, based on the instantaneous power flow balance concept, the harmonic domain, and Newton-Raphson method, is developed and explained in the thesis. This method is based on the instantaneous power balance as opposed to the active and reactive power balance, followed by traditional harmonic power flow methods. The power system and the power electronics controllers are modelled entirely in the harmonic domain.

This thesis investigates the operation of the current transfonner (CT) when sensing retum-to-zero current pulses in power electronic circuitry. The CT's output signal is nonnally rectified when sensing current pulses and the effects of the different rectification techniques on peak current and average current droop are evaluated. Initially, the various current sensing techniques and their application in power electronics circuits are reviewed. The CT and both diode and synchronous rectification are then reviewed in more detail. Operation of the CT with diode rectification (DR) and natural resetting is investigated. Three operating modes are identified. These are the discontinuous magnetizing current, continuous magnetizing current and discontinuous secondary current modes. The error (droop) in the average output signal obtained is found to be predominantly defined by CT core losses. Coefficients are given for correcting the error due to droop, provided that the discontinuous secondary current mode is avoided. Diode rectification with the dual CT arrangement is also investigated. Operation of the CT with synchronous rectification (SR) and natural resetting is then investigated. The SR topologies possible using a discrete MOSFET are categorized. During experimentation the arrangement used to drive the MOSFET's gate is found to be important if distortion is to be minimized. It also is found that the average current droop is dependent on the oscillatory behaviour of the resetting circuit and has an effectively random component. The magnitude of this component is defined by the voltage drop exhibited by the SR MOSFET's intrinsic anti-parallel diode. SR is then implemented using a commercially available analogue switch. The problems detailed with the use of a discrete MOSFET are largely alleviated. Another benefit is that the increased restriction on maximum duty factor imposed by introducing a discrete MOSFET is also eased. However, whichever SR technique is implemented, an operational amplifier is used and the transient response of this circuit element is important. A method of minimizing droop by indirect sensing of the CT's peak core flux excursion is then presented. A corresponding correcting voltage is applied in series with the CT's output terminals during a current pulse. The magnitude of this voltage is based on the magnitude of the resetting voltage sensed during previous switching cycles. A circuit is implemented and simulated. Experimental results are presented. A switched-mode circuit operating at a frequency higher than that of the main power circuit is then used to apply the correcting voltage with the objective of reducing the power drawn. Again, the circuit is implemented and simulated and experimental results are presented.

Streszczenie:
This thesis analyzes generator reactive power dispatch under restructured power systems from two different perspectives.
The first follows the two-step approach adopted by some electricity markets where first, the generators' real powers are dispatched in the energy market, followed by the dispatching of the generator reactive power support services in the ancillary services market.
Once the generators' real power has been dispatched in the energy market, the generators' reactive power is dispatched according to the minimization of a combination of multiple objectives: network MW loss cost, generator opportunity cost, and generator MW shift cost. The MW loss cost is represented as a function of bus voltage magnitudes and angles as well as the nodal prices in $/MWh found in the first step. Opportunity cost is represented as a function of the generator reactive powers, whose cost parameters are derived in terms of the MW dispatch, the MW nodal prices and the generators' capabilities. The generator shift cost is represented as a function of the generator real powers and the MW shift weighting factor. As these three objectives may conflict, compromises are needed to arrive at an optimum solution.
The second reactive power dispatch approach unifies real and reactive power dispatch by minimizing both MW and MVAr generation costs while enforcing the MW and MVAr/voltage constraints simultaneously. This unified dispatch avoids a disadvantage of the two-step MVAr dispatch, that is, that the MW price signal determined in the energy market may be distorted by the subsequent MVAr dispatch in the ancillary services market.
Several numerical examples under different conditions are presented to examine and compare the effectiveness of these two methods.

Power electronics represent a key technology for improving the functionality and performance, and reducing the energy consumption of many systems. However, the size, cost, and performance constraints of conventional power electronics currently limit their use. This is especially true in relatively high-voltage, low-power applications such as off-line power supplies, light-emitting diode (LED) drivers, converters and inverters for photovoltaic panels, and battery interface converters; a LED driver application serves as a motivation example throughout the thesis. Advances in the miniaturization and integration of energy-conversion circuitry in this voltage and power range would have a tremendous impact on many such applications. Magnetic components are often the largest and most expensive components in power electronic circuits and are responsible for a large portion of the power loss. As operating frequencies are increased, the physical size of the passives can, in theory, be reduced while maintaining or improving efficiency. Realizing this reduction in size and the simultaneous improvement in efficiency and power density of power electronic circuits requires improvements in magnetics technology. This thesis focuses on the challenge of improving magnetics through the analysis, optimization, and design of air-core toroidal inductors for integration into high-efficiency, high-frequency power electronic circuits. The first part of the thesis presents the derivation of models for stored energy, resistance and parasitic capacitance of microfabricated toroidal inductors developed for use in integrated power electronics. The models are then reduced to a sinusoidal-steady-state equivalent-circuit model. Two types of toroidal MEMS inductors are considered: in-silicon inductors (with or without silicon core) and in-insulator inductors. These inductors have low profiles and a single-layer winding fabricated via high-aspect-ratio molding and electroplating. Such inductors inevitably have a significant gap between winding turns. This makes the equivalent resistance more difficult to model. The low profile increases the significance of energy stored in the winding which, together with the winding gap, makes the equivalent inductance more difficult to model as well. The models presented in this thesis account for these effects. In the case of in-silicon inductors, magnetically and electrically driven losses in different regions of silicon are modeled analytically as well. The second part of the thesis focuses on the optimized design of microfabricated toroidal inductors for a LED driver. The models developed in the first part of the thesis allow optimization of inductor designs based on objectives such as minimizing substrate area, maximizing efficiency, and simplifying the fabrication process by maximizing minimum feature size. Because the magnetics size and loss depend strongly on the driver design parameters, and the driver performance depends strongly on the inductance value and loss, the simultaneous optimization of driver components and magnetics parameters is used in the design process. The use of computationally efficient models for both magnetics and other circuit components permits numerical optimization using the general co-optimization approach. Finally, a multi-dimensional Pareto-optimal filtering is applied to reduce the feasible design set to those on the multi-objective optimality frontier. For the case of LED drivers, the current state of the art efficiencies range from 65% to 90%. The co-optimization process results in efficiencies greater than 90% while reducing the size of the LED driver by 10 to 100 times compared to the commercially available LED drivers. This is a significant improvement in both the efficiency and the size of the LED drivers. In the resulting designs, the magnetics are no longer the largest part of the circuit. In the third part of the thesis several numerical and experimental tests are presented. The models developed in this thesis, are verified against results from 2D FEA, 3D FEA, direct measurement of MEMS fabricated devices (for both in-insulator devices for flip-chip bonding and in-silicon devices for direct integration), and in-circuit experimentation of the fabricated devices. These tests show that the equivalent-circuit models presented in this thesis have greater accuracy than existing models. The results also show that these models are good enough to support the LED driver optimization.

Cataloged from student-submitted PDF of thesis.
Includes bibliographical references (pages 77-80).
The quest for a suitable wide-bandgap semiconductor for high-power and high-frequency applications is well motivated; wide-bandgap semiconductors generally exhibit a high breakdown field and can therefore support a high voltage over short distances. Diamond (Bandgap of 5.5 eV) in particular is an attractive prospect since its thermal conductivity and radiation hardness well surpass other wide-bandgap semiconductors. However, practical transistors require the ability to engineer the charge density through substitutional doping which has proven to be difficult considering the strong covalent bonds that make up bulk diamond. In this work, we utilize hydrogen-passivated diamond surface along with surface acceptors to generate a highly conductive 2D hole sheet at the surface with carrier densities going up to 10¹⁴ cm⁻². Surface transfer doping using stable high electron affinity transition-metal oxides (TMO) such as WO₃ in conjunction with the novel contact-first process explored in this work shows great promise on advancing process stability while attaining the high current densities desired in the future of power diamond transistors. We closely examine the H-terminated diamond/TMO interface using a numerical approach based on a Schrödinger-Poisson solver package. We identify key inconsistencies in the generic valence-to-conduction transfer model for both shallow and deep TMO electron affinity regimes. We report that introducing deep level impurities in the TMO have shown improvements to the effect of bias modulation and agreement with experiments for low TMO affinities. A solution for engineering a preexisting TMO with fixed affinity and trap level is presented through TMO thickness engineering. The methods explored in this work show promise towards the enhancement of diamond conductivity and reproducibility.

Streszczenie:
The coupled effects of mechanical stress and thermal expansion on the electrical function of power electronic circuits are explored within a new analytical framework called thermomechatronics. The problem of interest is the progressive performance degradation of the power electronics owing to the growth of thermomechanically induced fatigue cracks within the die-attach interlayer between power devices and substrates. Building on previous efforts, the present analysis focuses on experimentally confirming the system-level degradation of a simple power electronics circuit subject to variations in junction temperature of the electronics that would result from variations in interlayer damage.

Streszczenie:
Power electronics are used in wind turbines to convert variable voltages and frequencies produced by the generator to fixed voltages and frequencies compliant with an electrical grid with minimal losses. The power electronic system is based on a series of three-phase pulse width modulated (PWM) power modules consisting of insulated-gate bipolar transistor (IGBT) power switches and associated diodes that are soldered to a ceramic substrate and interconnected with wirebonds. Power electronics can generate thermal loads in the hundreds of watts/cm2, therefore the design of the packaging and cooling of the electronics is crucial for enhancing their energy efficiency and reliability. Without adequate heat removal, the increase in device temperature will reduce the efficiency of power electronic devices, leading to thermal runaway and eventual failure of the entire power electronic system. Furthermore, the increased temperatures can lead to failure of the packaging elements. Turbines utilizing these power electronics are often placed in harsh and inaccessible offshore environments; power electronic failures causing unscheduled maintenance lead to costly repairs. This paper will provide an overview of the fundamental package level mechanisms that can cause failures in the power electronic system. These include wirebond and lead fatigue, die attach fatigue, substrate cracking, and lead micro-voids. Attention will then be given to the reliability of a plastic-insert liquid cold plate used to manage the thermal loads from the power electronics.
