Phasor Power Electronics


Book Description

This book presents a comprehensive introduction to the principles of power electronics, focusing on the switched transformer concept and phasor transformation techniques as employed in the analysis and design of power electronic circuits. Phasor transformations, as introduced in this book, make the time-varying nature of a switching converter simple and easy to handle, transforming it into an equivalent time-invariant circuit. The book starts with an introduction to the philosophy and fundamental principles of power electronics. The switched transformer concept, which is applicable to any switching converter, is introduced, and it is shown how DC-DC converters analyses are then so straightforward that very little equational manipulation is needed. Then the phasor transformation techniques are comprehensively explained over three parts. Single phase and multi-phase AC systems are dealt with through the single phase phasor transformation and circuit DQ transformation, respectively. A general unified phasor transformation is then introduced for the static and dynamic cases. The final part of the book considers current and potential extensions of the technique in various fields of application, including wireless power transfer, signal processing, power systems and renewable energy. The book avoids the piece-wise linear circuit models used in other titles, with which the mathematical results become too complicated to be used in practice. No cumbersome equations or matrix manipulations are needed with the phasor transformation techniques introduced in this book. It will be a valuable reference source for engineering students and practising researchers in power electronics and related areas.

Dictionary of Environmental Health


Book Description

Every branch of science, every profession, and every engineering process has its own language for communication. Environmental health is no different. To work even at the edge of the major environmental aspects of this challenging field, you must acquire a fundamental but wide-ranging vocabulary and understanding of the components that make it up. As Voltaire said: "If you wish to converse with me, define your terms." In this publication, we define, and in many instances, fully explain in plain English, the terms or "tools" (concepts and ideas) used by environmental health professionals, environmental science professionals, safety/industrial hygiene practitioners/engineers, and non-science professionals. It is important to point out that environmental health is not a single topic, but rather a complex, colorful, and diversified range of interrelated subjects including all of the basic sciences, computer science, government, engineering, energy, renewable energy, hydraulic fracking, security, disease, industrial hygiene, injury identification prevention and control, and much more. The practicing environmental health professional, specialist, technician or student of environmental health should know these topics—without them it is difficult, if not impossible, to practice in any of the environmental fields. The Dictionary of Environmental Health is a one-of-a-kind comprehensive reference that serves as both a dictionary and encyclopedia. This book is an indispensable resource for individuals throughout environmental, occupational, and public health industries. It defines thousands of words illustrating the enormous magnitude of the environmental health field. Terms are alphabetically arranged with concise and succinct definitions along with expanded explanations wherever needed. These terms and definitions are drawn from varied, specialized, and technical environmental fields that can be understood by professional, students, and general readers alike.

Assessment of Solid-State Lighting, Phase Two


Book Description

The standard incandescent light bulb, which still works mainly as Thomas Edison invented it, converts more than 90% of the consumed electricity into heat. Given the availability of newer lighting technologies that convert a greater percentage of electricity into useful light, there is potential to decrease the amount of energy used for lighting in both commercial and residential applications. Although technologies such as compact fluorescent lamps (CFLs) have emerged in the past few decades and will help achieve the goal of increased energy efficiency, solid-state lighting (SSL) stands to play a large role in dramatically decreasing U.S. energy consumption for lighting. Since the publication of the 2013 National Research Council report Assessment of Advanced Solid-State Lighting, the penetration of SSL has increased dramatically, with a resulting savings in energy and costs that were foreshadowed by that study. What was not anticipated then is the dramatic dislocation and restructuring of the SSL marketplace, as cost reductions for light-emitting diode (LED) components reduced profitability for LED manufacturers. At the same time, there has been the emergence of new applications for SSL, which have the potential to create new markets and commercial opportunities for the SSL industry. Assessment of Solid-State Lighting, Phase Two discusses these aspects of changeâ€"highlighting the progress of commercialization and acceptance of SSL and reviewing the technical advances and challenges in achieving higher efficacy for LEDs and organic light-emitting diodes. This report will also discuss the recent trends in SSL manufacturing and opportunities for new applications and describe the role played by the Department of Energy (DOE) Lighting Program in the development of SSL.
