Emerging applications of power electronics introduce challenging design requirements. Increasing the system complexity in appropriate ways can bring many advantages, yielding reduced system volume and/or improved system performance. This thesis explores new circuit design techniques that can leverage the advantages of merged multi-stage power conversion through a hybrid switched-capacitor/magnetics approach. Multiple circuits and system aspects of this approach are investigated in this thesis. A 70 W grid-interfaced solar micro-inverter with a multilevel energy buffer and voltage modulator (MEB) is developed to demonstrate the advantages of a merged multi-stage system in dc-ac applications. By synthesizing a multilevel voltage in pace with the ac grid voltage using the energy buffer, the wide operation range of the inverter stage is compressed, leading to a significantly improved overall system performance. A high-power-density wide-input-voltage-range isolated dc-dc converter with a Multi- Track power conversion architecture is also investigated. The MultiTrack architecture delivers power in multiple voltage domains and current tracks. It incorporates multiple distributed circuit cells, and benefits from the way they are merged together. By changing the use of multiple cells according to the system operating condition, the overall device utilization of the system is enhanced, leading to significantly improved power density as compared to conventional designs while maintaining high efficiency. The prototype 18 V-80 V input, 5 V output, 75 W isolated dc-dc converter achieves 453.7 W/inch3 power density, which is 3x higher than the best commercial product presently available. It maintains high efficiency across a wide (>4:1) input voltage range, and has a peak efficiency of 91.3%. Advanced magnetics structures are an enabling technique on the path to improved power conversion. This thesis developed a systematic approach to modeling impedances and current distribution in planar magnetics. It captures electromagnetic coupling relationships using an analytical lumped circuit model, and enables rapid evaluation of planar magnetics designs. The effectiveness of the model is verified by numerical methods and experimental measurements. A software package - M2Spice - that can rapidly convert design information into SPICE netlists has been developed and is being utilized in many real designs.

The most complete and up-to-date handbook on power generation from coal, this book covers all of today's new, cleaner methods for creating electricity from coal, the environmental challenges and concerns involved in its production, and developing technologies Coal accounts for approximately one quarter of world energy consumption. Of the coal produced worldwide, approximately 65% is shipped to electricity producers and 33% to industrial consumers, and most of the remainder goes to consumers in the residential and commercial sectors. The total share of total world energy consumption by coal is expected to increase to almost 30% in 2035. This handbook describes the challenges and steps by which electricity is produced from coal and deals with the challenges for removing the environmental objections to the use of coal in future power plants. New technologies are described that could virtually eliminate the sulfur, nitrogen, and mercury pollutants that are released when coal is burned for electricity generation. In addition, technologies for the capture of greenhouse gases emitted from coal-fired power plants are described and the means of preventing such emissions from contributing to global warming concerns.

A comprehensive guide to approaches to decoding, synthesizing and modeling pulse width modulation (PWM) converters Origin of Power Converters explores the original converter and provides a systematic examination of the development and modeling of power converters based on decoding and synthesizing approaches. The authors—noted experts on the topic—present an introduction to the origins of the converter and detail the fundamentals related to power the converter’s evolution. They cover a range of converter synthesis approaches, synthesis of multi-stage/multi-level converters, extension of hard-switching converters to soft-switching ones, and determination of switch-voltage stresses in the converters. In later chapters, this comprehensive resource reviews conventional two-port network theory and the state-space averaged (SSA) modeling approach, from which systematic modeling approaches are based on the graft switch technique. In addition, the book reviews the converter layer scheme and some fundamental circuit theories. This important book: • Contains a review of several typical transfer codes, such as step-down, step-up, step-up&-down, and ± step-up&-down • Describes the syntheses of pulse width modulation (PWM) converters such as voltage-fed z-source, current-fed z-source, quasi z-source, switched capacitor, and switched inductor converters • Presents two application examples based on previously proposed modeling approaches Written for academic researchers, graduate students, and seniors in power electronics, Origin of Power Converters provides a comprehensive understanding of the evolution of the converter and its applications.

This book describes two target applications for synchronous systems: regulated 3-phase voltage supply and voltage sag mitigation. It presents a detailed design procedure for converter switches and filters considering all steady-state, commutation and dynamic requirements. This work has evolved from previously published research by the authors, which in turn is part of a larger effort to expand the application domain of matrix converters to power systems. The objectives of the work have been categorized into the following: developing a dynamic model that provides adequate design insights; designing filters; and devising a control scheme. The low frequency dynamic model is first analyzed for regulated voltage supplies assuming balanced system. The system is modeled relative to a synchronous rotating (dq) frame linearized around an operating point. The input–output variables are related by non-diagonal transfer function matrices. Individual transfer function sub-matrices are sequentially investigated and it is shown that, depending on the input power, input voltage and filter parameters, the appearance of a set of right half zeros is possible. The book then considers filter design, as well as general issues like ripple attenuation, regulation, reactive current loading, and filter losses. The book also addresses additional constraints that may be imposed by dynamic requirements and commutation. In the third stage, voltage controller design is detailed for a 3-phase regulated voltage supply. In dq domain, output voltage control represents a multivariable control problem. This is reduced to a single variable control problem while retaining all possible right half zeros, thereby preserving the internal stability of the system. Consequently, the standard single variable control design technique has been used to design a controller. The analytically predicted dynamic response has been verified by experimental results. It was possible to operate the system beyond the critical power boundary where the right half zeros emerge. Lastly, the developed control approach has been extended to voltage sag mitigation with adequate modifications. A 3-wire linear load and both symmetrical and asymmetrical voltage sags have been considered. Experimentally obtained response time for sag mitigation was found to be less than the power supply holdup time of most of the sensitive equipment. This book will be useful to both researchers and graduate students.
