▼ GaN and related materials have become one of the most promising material systems for high efficiency power electronics due to their unique material properties, such as a high critical electrical field, large band gap, high electron saturation velocity, large electron mobility, and high thermal conductivity compared with alternatives, such as Si, GaAs and SiC. However, the actual performance of many lateral GaN devices has fallen short of expectations, including large ideality factors, the inability to achieve avalanche breakdown, dynamic on-state resistance, current collapse, and hysteresis in FETs. Unlike other power device options, most GaN devices are built on lattice-mismatched non-native substrates such as sapphire or SiC because of the high cost and limited availability of bulk GaN substrates. These foreign substrates result not only in large dislocation densities, but also limited thermal conductance for heat removal. This work focuses on the development of several GaN power device concepts, such as Schottky diodes and p-n diodes for high efficiency power switching applications, made possible by vertical device architectures. The prospects for, and benefits of fabrication processing using epitaxial lift-off (ELO) using band gap selective photoelectrochemical (PEC) etching techniques are also examined. Vertical devices are advantageous for power applications because they can utilize thick low-doped drift layers to achieve higher breakdown voltages. This leads to smaller die sizes than comparable lateral devices. On the other hand, vertical devices are more sensitive to the presence of threading dislocations and thus must be made on high quality bulk GaN substrates for best performance. ELO technology has the potential to allow cost-effective device production using native GaN substrates through substrate re-use, as well as to improve thermal performance of devices by eliminating the thermal resistance associated with conventional substrates by enabling direct thermal and electrical bonding. To investigate vertical GaN devices and the potential benefits of ELO processing, Schottky diodes and p-n junction diodes have been fabricated and tested. The Schottky device results suggests that ELO processing could potentially improve device performance for devices on non-native substrates. In addition, to realize high-voltage, high-current vertical GaN-on-GaN power diodes and surmount the limitations of mesa-isolated power diodes, we developed a new vertical p-n diode design with ion-implantation edge termination (ET), sputtered SiNx passivation and back-side cathode contacts. The measured devices exhibit a breakdown voltage exceeding 1.68 kV, with differential specific on resistances of 0.15 mOmega-cm2. A Baliga’s figure-of-merit (BFOM) of 18.8 GW/cm2 is obtained; this is among the highest reported BFOMs for GaN homoepitaxial p-n diodes. These devices also exhibit near-ideal scaling with area, enabling currents as high as 12 A for a 1 mm diameter device. To investigate the effect of ELO processing on devices on… Advisors/Committee Members: Patrick Fay, Research Director, Anthony Hoffman, Committee Member, Alan Seabaugh, Committee Member, Douglas Hall, Committee Member.

M.Ing. (Electrical & Electronic Engineering)

The technology of the use of electronic devices as power switches is still being developed. Because of the increasing demand for low mass and cost, the switching frequency must be as high as possible. The limiting factor for the frequency is the energy loss which is dissipated in the semiconductor crystal during each switching-transient. If tllis switching loss can be reduced, a higher frequency can be obtained. The switching loss is due to the non-instantaneous switching process of the semiconductor device. For the reduction of this switching loss, the device must be switched as fast as possible via its control-electrode. Further improvement can be obtained through the use of snubber networks. This thesis considers the bipolar high-voltage transistor as a power switch. The unfavourable switching loci of the transistor- switch is discussed in chapter 1. In chapter 2 the basedrive during transistor turn-off is investigated, in order to reduce the turn-off time. The following chapters de;al with the use of snubber circuits, which relieve the transistor during turn-on and turn-off. The advantages, as well as the disadvantages and limitations of snubbers are discussed. After the linear turn-off and turn-on snubbers have been treated, the non-linear turn-on snubber, which uses a saturable inductor, will be considered from an experimental point of view. The results show that this snubber is very effective in relieving the transistor during turn-on. In chapter 7 the non-linear turn-off snubber is treated on an experimental as well as on a mathematical bas e . Cri teria, which must be satisfied for realisation of a practical nonlinear capacitor, is also laid down. Because of the fact that a first order snubber is always loading the transistor during the complimentary switchin,]-transient, chapter 8 deals with a second order snubber, which consists of both a capacitor and an inductor. Experimentally it was found that the turn-on time is reduced with the use of a turn-on snubber, while the turn-off time is increased with the use of a turn-off snubber. In chapter 9 the physical behaviour of the switching processes is investigated, after which the influences of the snubbers on the switching times is explained qualitatively...

▼ Currently there is a push for higher switching frequency DC-DC converters, especially in mobile and computer applications. Higher frequency operation allows for better transient performance and a reduction in the size of magnetic components. This leads to converters with a higher power density. However, certain challenges arise from operating at higher switching frequencies. Focusing on the Synchronous Buck Converter, efficiency may be degraded due to higher switching loss, higher diode conduction loss, and higher gate drive loss. To increase efficiency, different gate drive configurations have been designed with the goal of minimizing losses for MOSFETs being switched at high frequencies. Higher efficiency operation at higher frequencies can be accomplished with resonant gate drives, which include an inductor in the gate drive. The advantages may include: a high, constant gate current that enables faster switching and the possibility to return gate drive current to the source as opposed to ground. However, few gate drives are able to capture both these advantages – the ones that do suffer from other disadvantages such as high component counts, high complexity, and high conduction loss in the gate drive. An Asymmetric Complementary Dual Channel Current Source Driver is proposed in this thesis specifically designed for a Synchronous Buck Converter. Merits include: a constant, high gate current used to switch the Control MOSFET and Synchronous MOSFET; discharging the MOSFETs to the source, reducing gate drive losses; lower component count than other designs; and lower conduction loss due to reduced precharge and discharge intervals versus other designs. There are two sides to the gate drive: one driving the Control MOSFET, the other driving the Synchronous MOSFET. A coupled inductor links the two sides of the gate drive and transfers charge between the gates of the MOSFETs. The proposed gate drive is specifically designed to maximize efficiency when applied to a Synchronous Buck Converter. The efficiency is verified and compared via analysis and simulation, the operation of the gate drive was verified via simulation and experimentally.

▼ Control of microgrids, as the main building blocks of the future smart power grid, is an important problem which has initiated many research activities in recent years. The microgrid should appear to the power grid as a single united entity, in which the majority of distributed energy resources are interfaced through voltage source converters (VSCs). In dynamic situations, specific structure, natural nonlinearity, and low physical inertia of VSCs may lead to higher sensitivity to network disturbances and power oscillations and in occasions result in violation of overall stability; hence the need for fast and flexible control techniques in the microgrid is evident. The design simplicity and easy implementation of PI controllers have resulted in their popularity in controlling VSCs; however their application is associated with a number of drawbacks such as poor harmonics attenuation and unsatisfactory operation in case of load changes and high penetration of distributed generators. In this Ph.D. thesis, three different control algorithms are proposed for VSCs in microgrid systems. The control systems are based on the adaptive critic-based control concept and employ an element called critic whose task is to evaluate the credibility of the performance and compare it with the desired goals. The critic’s evaluations are then used in an on-line procedure to update the controller parameters during dynamic transients. The critic-based control idea is used in conjunction with PI and neuro-fuzzy controllers. With the proposed approach, the need for precise design of the controller is removed, and because of the supervisory role of the critic, no complicated mathematical calculations are required for its design. This fact increases the degree of intelligence and adaptivity against changes such as high penetration of distributed generators and dynamically demanding situations like presence of motor loads and results in a self-tuning and non-model-based control system with high computational speed. The simulation results verify that the application of the proposed approach significantly improves the dynamic performance by reducing the convergence time, output oscillations, tracking error, and unwanted current harmonics and confirm the effective control in case of high penetration of distributed generators.

D.Ing. (Electrical and Electronics Engineering)

This thesis treats aspects of the modelling techniques required for Computer Aided Design (CAD) of electromagnetically integrated structures for use in power electronic networks. The concept of structural impedance is introduced and developed, building on transmission line theory. Computer based methods for calculating the distributed parameters of a given structure are investigated. These methods are the Finite Element Method and the Incremental Method. Based on the structural impedance lumped element equivalent circuit models for interconnections are developed for modelling of the distributed energy storage effects associated with a physical circuit as part of a lumped element network that can be submitted to circuit simulation programs like SPICE. The models are used in SPICE circuit simulations of power circuits and the simulated results are verified experimentally. Circuit level simulation models for switches are investigated in order to determine the complexity and detail of models suitable for CAD of complete converter topologies. A classification scheme for circuit models of switches is developed as an aid in selection of suitable models for particular simulation purposes. A DC circuit model for power BJT's is developed as a theoretical exercise to determine the requirements, with regard to development time and computational resources, for application of a particular switch model. It is based on new ideas in an attempt to model the effects of power BJT operation of interest to power electronic circuit designers while decreasing the calculation requirements in comparison with sophisticated device physics based models normally used or over simplified models. Finally suggestions are made with regard to a new way of approaching the optimization of power conditioning circuits by using power flow as the basis. This includes the novel use of specially manufactured high permittivity dielectric materials to adjust the characteristic impedance of connections to obtain optimal operation under particular operating conditions.

M.Ing. (Electrical and Electronic Engineering)

Recent world events such as the fall of Communism. attempts at the unification of Europe and the reaching of the most extensive international trade agreement yet (GATT ::: General Agreement on Trade and Tariffs). have all contributed to the expansion of world markets as well as a marked intensification in the competition in those markets. Rivalry in the market for power electronic equipment is as relentless as in any other. Strict regulations with regard to Electromagnetic Interference (EMf) and Electromagnetic Compatibility (EMC) apply in Europe and compliance with these standards is legally enforced. In South Africa, compliance with such standards is merely recommended, hence local manufacturers have not yet considered these phenomena seriously enough to pose a threat to their European opposition. The two main causes of EMI are switching action, which is such an integral part of power electronics, and the excitation of parasitic circuit elements. This thesis describes the investigation carried out to determine the effect of certain layout and construction parameters on the generation of EMf. Parasitic loop inductances, self-capacitances of coils and the ground connection of heat sinks were examined in the process. A test convener containing a full-bridge converter perfonning DC·DC conversion, was built. These converters are important building blocks for equipment such as uninterruptible power supplies. One configuration of this converter was designated as the reference configuration. For every modification of a layout or construction parameter its effect on the interference spectrum was determined through a comparison with the measured interference spectrum of the reference configuration. The use of snubbers and the minimisation of the self-capacitances of inductors in an output filter effected a marked decrease in the measured interference spectrum (approximately 10 dB or a third less). Certain loop inductances have to be minimised in the design stages through proper layout of conveners, and heat sinks should preferably be grounded through high resistances. Paying due attention to these aspects in the design of power electronic converters can aid in decreasing the size and cost of bulky, expensive EMf filters required to meet the standards. It could give local manufacturers a considerable advantage over their overseas competitors.

▼ Wind is one of the most promising renewable energy forms that can be harvested to into the electrical power system. The installation has been rising worldwide in the past and will continue to steadily increase. The high penetration of wind energy has bought about a number of difficulties to the power system operation due to its stochastic nature, lack of exhibited inertia, and differing responses to the traditional energy sources in grid disturbances. Various grid support functions are then proposed to resolve the issues. One solution is to allow the renewable energy sources to behave like a traditional synchronous generator in the system, as a virtual synchronous generator (VSG). On the other hand, testing the control of the future power grid with high penetration renewable often relies on digital simulation or hardware-based experiments. But they either suffer from fidelity and numerical stability issues, or are bulky and inflexible. A power electronics based power system emulation platform is built in the University of Tennessee. This Hardware Testbed (HTB) allows testing of both system level and component level controls, with a good balance between the fidelity of the hardware-based testing platform, and the coverage of the digital simulation.This dissertation proposal investigates the VSG operation of the full converter wind turbine (FCWT), focusing on its control and testing in the HTB. Specifically, a FCWT emulator was developed using a single converter to include its physical model and control strategies. The existing grid support functions are also included to demonstrate their feasibility.The comprehensive VSG controls are then proposed for a FCWT with short term energy storage. The dynamic response of the FCWT can be comparable to the traditional generation during grid disturbance. The control can also allow the FCWT to be dispatched by the system operator, and even operate stand-alone without other grid sources.To study the system response under faults, a short circuit fault emulator was developed in the HTB platform. Four basic types of the short circuit faults with various fault impedance can be emulated using the emulator. The power system transient stability in terms of critical clearing time can be measured using the developed fault emulator.

▼ Incandescent lamps are now being gradually replaced by Compact Fluorescent Lamps (CFLs) as CFLs consume less power to produce the same light output and its lifetime is much longer than that of an incandescent lamp. However, current CFLs have the following drawbacks: (1) the line current drawn from the CFL produce a large amount of unwanted harmonics that results in very poor input power factor; (2) the dimming performance of a CFL with conventional incandescent lamp dimmers is very poor. The performance of the CFL depends on the design of the electronic ballast circuit that is located at the base of each CFL. For a CFL electronic ballast to be practical, its size and cost is of utmost importance. Thus, the main challenge in the design of practical dimmable CFL ballasts is to solve the aforementioned CFL performance issues while minimizing its size and cost. In the first part of this dissertation, two novel high power factor single-stage electronic ballast topologies are proposed to solve the poor power factor issue of the CFLs that are currently on the market. Both proposed circuits have the following advantages: (1) only one switch is required in the power circuit; (2) the switch has both lower current and voltage stress than other conventional circuits; (3) the built-in power factor correction (PFC) circuit allows incandescent phase-cut dimmer to be used for dimming the CFL; (4) the circuit design is simple and it requires less system space compared to other conventional high PF electronic ballast topologies. The second part of this dissertation proposes a new control circuit that enables the lamp to maintain high power factor throughout the majority of the dimming range. In the proposed control scheme, the dimmer phase-cut angle is fed-forward to the control circuit. The controller then determines the proper duty cycle based on the phase-cut angle to facilitate the desired dimming operation. This novel control circuit was first implemented using analog circuitry. After assessing the performance of the analog version of the proposed controller, it was then digitally implemented through the Field Programmable Gate Array (FPGA) technique. The feasibility and performance of both the proposed electronic ballasts and control concept have been verified through theoretical analysis, simulation and experimental results on a 13W 4-pin D/E CFL from Osram Sylvania.

▼ This thesis presents new control approaches for improving the performance, stability, and efficiency of a single-phase grid-connected voltage source inverter (VSI) with an LCL filter that is used in renewable energy power conditioning applications. There are two main controllers that need to be designed: an external DC-bus voltage controller to balance the power flow coming into the VSI, and an internal current controller to control the current injected by the VSI into the utility grid. This thesis aims to find well-tailored control approaches for the aforementioned control loops. First, the stability and behavioral characteristics of the open-loop VSI with an LCL filter are explored using a Poincaré map, and the open-loop system is found to have marginal stability. A current control method is proposed, called composite nonlinear feedback (CNF), which offers significantly improved overall performance compared to the state-of-the-art proportional resonant (PR) controller with state feedback. To reduce the overall number of sensors in the system, two different observers are implemented to estimate the VSI state variables: (1) the Luenberger observer (LO), and (2) the sliding mode observer (SMO). To balance the system power flow, a new DC-bus voltage droop control method is proposed, that provides fast performance during transients. This control approach includes a novel discrete DC-bus voltage sensing technique, which effectively removes the double frequency ripple from the DC-bus voltage signal and prevents it from propagating into the current control loop. A variant on the DC-bus voltage droop control method, called adaptive droop control is proposed, which adaptively changes the droop gains in order to regulate the DC-bus voltage to a constant value. Finally, another variant on the DC-bus voltage droop control method is proposed, called optimized adaptive droop control, which adaptively changes the gains of the controller in order to minimize the overall system power losses. A stability analysis is conducted using the singular perturbation control theory, which allows a nonlinear dynamical system to be broken down into subsystems with different time scales. The results of the stability analysis confirm that the proposed closed-loop grid-connected VSI with an LCL filter is locally stable.

▼ Large-scale photovoltaic power plants are becoming popular worldwide owing to the cost reduction in all parts of the solar power system, conversion efficiency improvement and the efforts from both governments and commercial companies to seek for new, clean, and sustainable energy sources. Inverters are important parts that connect the photovoltaic modules to the grid. Compared to the conventional two-level inverters, multilevel inverters feature improved harmonic performance with a reduced switching loss. Among all multilevel conversion topologies, the cascaded H-bridge converter is considered as one of the most promising candidates for the next-generation large-scale photovoltaic inverters.However, the solar irradiance and temperature conditions may vary significantly in a large-scale solar power plant. As a result, the bridges connected to different photovoltaic arrays are expected to generate different amounts of power. The thesis deals with the challenge to provide three-phase balanced grid currents when the power imbalance problem occurs.To begin with, several new zero-sequence injection methods are presented, featuring superior power balance capabilities to guarantee balanced currents under severe power imbalance. The optimal zero-sequence injection, in terms of the power balance capability, is also presented and proved to be the optimal solution of the star-connected H-bridge converter.Furthermore, the power balance capabilities of the presented zero-sequence injection methods are evaluated from both theoretical and practical perspectives. Additionally, the fault-tolerant scheme allowing the cascaded H-bridge to continue the operation after one or more bridges are bypassed owing to faults is presented. Different to the fault-tolerant scheme of the same converter with other applications, the unique problem of power imbalance in the photovoltaic application is taken into consideration.Finally, the delta-connected cascaded H-bridge converter is presented as an alternative to the star-connected converter. The converter overratings (both voltage and current), required by the star and delta-connected cascaded H-bridge converters to cope with all theoretically possible power imbalance cases, are compared to demonstrate that the delta-connected converter features significantly less converter overrating.All the findings are analyzed theoretically and verified experimentally with a converter prototype built in the laboratory.
