Описание: Offering step-by-step, in-depth coverage, the new Third Edition of Power Electronics: Converters, Applications, and Design provides a cohesive presentation of power electronics fundamentals for applications and design in the power range of 500 kW or less. The text describes a variety of practical and emerging power electronic converters made feasible by the new generation of power semiconductor devices. The new edition is now enhanced with a new CD-ROM, complete with PSpice-based examples, a new magnetics design program, and PowerPoint slides.
Описание: After nearly a decade of success owing to its thorough coverage, abundance of problems and examples, and practical use of simulation and design, Power-Switching Converters enters its second edition with new and updated material, entirely new design case studies, and expanded figures, equations, and homework problems. This textbook is ideal for senior undergraduate or graduate courses in power electronic converters, requiring only systems analysis and basic electronics courses. The only text of such detail to also include the use of PSpice and step-by-step designs and simulations, Power-Switching Converters, Second Edition covers basic topologies, basic control techniques, and closed-loop control and stability. It also includes two new chapters on interleaved converters and switched capacitor converters, and the authors have added discrete-time modeling to the dynamic analysis of switching converters. The final two chapters are dedicated to simulation and complete design examples, respectively. PSpice examples and MATLAB scripts are available for download from the CRC Web site. These are useful for the simulation of students' designs. Class slides are also available on the Internet. Instructors will appreciate the breadth and depth of the material, more than enough to adapt into a customized syllabus. Students will similarly benefit from the more than 440 figures and over 1000 equations, ample homework problems, and case studies presented in this book.
Описание: The first part of the book will introduce semiconductor power devices, describing the characteristics of static and dynamic DC voltage regulators and power MOSFETs (metal-oxide semiconductor field effect transistors). The treatment of silicon/silicon carbide power diodes/power MOSFETs will be a unique feature of the book; innovative power semiconductor devices that have not been covered in previous titles but should be presented to designers/future designers of switching-mode power supplies because of their potential in this area of the technology. The book will then go on to discuss transformerless converters, such as buck, boost, and buck-boost converters. Each will be ensured clear and complete coverage by having a separate chapter devoted to it. Transformer converters, such as flyback, forward, half-bridge, full-bridge, and push-pull converters will be analysed next, with summaries and design procedures. Time intervals for each are to be supplied, and other expressions for various parameters of the converters will be derived and illustrated. Examples are DC voltage transfer function (conversion ratio), component values, device stresses, output voltage ripple, power losses in all components, and the converter efficiency. High-frequency inductors and transformers will be considered in depth toward the end of the book, along with magnetics. Review questions and problems at the end of each chapter will be included, so that students can fully engage with the information. A solutions manual will be provided for professors wishing to use the text on their power electronics course.
Описание: "Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters" investigates the feasibility of designing Delta-Sigma Analog to Digital Converters for
very low supply voltage (lower than 1.5V) and low power operation in standard CMOS processes. The chosen technique of implementation is the Switched Opamp Technique which
provides Switched Capacitor operation at low supply voltage without the need to apply voltage multipliers or low VtMOST devices. A method of implementing the classic single loop and
cascaded Delta-Sigma modulator topologies with half delay integrators is presented.
Those topologies are studied in order to find the parameters that maximise the
performance in terms of peak SNR. Based on a linear model, the performance degradations of higher order single loop and cascaded modulators, compared to a hypothetical ideal
modulator, are quantified.An overview of low voltage Switched Capacitor design techniques, such as the use of voltage multipliers, low VtMOST devices and the Switched Opamp
Technique, is given. An in-de
th discussion of the present status of the Switched Opamp Technique covers the single-ended Original Switched Opamp Technique, the Modified Switched Opamp Technique, which
allows lower supply voltage operation, and differential implementation including common mode control techniques.
The restrictions imposed on the analog circuits by low
supply voltage operation are investigated. Several low voltage circuit building blocks, some of which are new, are discussed. A new low voltage class AB OTA, especially suited for
differential Switched Opamp applications, together with a common mode feedback amplifier and a comparator are presented and analyzed.As part of a systematic top-down design
approach, the non-ideal charge transfer of the Switched Opamp integrator cell is modeled, based upon several models of the main opamp non-ideal characteristics.
simulations carried out with these models yield the required opamp specifications that ensure that the intended performance is met in an implementation. A power consumption analysis is
performed. The influence of all design parameters, especially the low power supply voltage, is highlighted.Design guidelines towards low power operation are distilled.
implementations are presented together with measurement results.The first one is a single-ended implementation of a Delta-Sigma ADC operating with 1.5V supply voltage and
consuming 100 W for a 74 dB dynamic range in a 3.4 kHz bandwidth. The second implementation is differential and operates with 900 mV. It achieves 77 dB dynamic range in 16 kHz
bandwidth and consumes 40 W.

Описание: An integrated and comprehensive theory of PWM The selection of the best algorithm for optimum pulse width modulation is an important process that can result in improved converter efficiency, better load (motor) efficiency, and reduced electromagnetic interference. However, the identification of the best approach is a complex process requiring extensive mathematical manipulation. Pulse Width Modulation for Power Converters: Principles and Practice is the first single-volume resource written to help researchers in the field attain a working knowledge of the subject. The authors bring together today's seemingly diverse approaches into a single integrated and comprehensive theory of modulation. The book provides a generalized approach to the fundamentals of PWM, looking at: Active switch pulse width determination Active switch pulse placement within a switching period Active switch pulse sequence between phase legs and across switching periods The main benefit of this generalized concept is that once the common threads are identified, the selection of a modulation strategy for any converter topology becomes immediately clear, leaving only secondary factors, such as practical performance, cost, and difficulty of implementation to consider. Additionally, it allows the performance of any particular converter topology and PWM strategy to be quickly and easily identified without complex and time-consuming analysis. Pulse Width Modulation for Power Converters: Principles and Practice enables the reader to achieve optimum PWM results for any application.

Описание: Power converters are at the heart of modern power electronics. From automotive power systems to propulsion for large ships, their use permeates through
industrial, commercial, military, and aerospace applications of various scales. Having reached a point of saturation where we are unlikely to see many new and revolutionary
technologies, industry now seeks to optimize and standardize the performance of these devices.
"Power-Switching Converters: Medium and High Power" examines the
characteristics and operating principles of these systems in terms of how to increase their efficiency and produce them at lower cost. This book begins with an introduction to the field,
placing the technology in its business context to highlight the current trends and issues facing the modern power engineer. The remainder of the book provides a detailed examination of
three-phase power switching converters, including the various problems and solutions involved in different applications.
It discusses high-power semiconductor devices,
pulse-width modulation (PWM) principles and algorithms for various implementations, closed-loop current control, component-minimized topologies, power grid interface, parallel and
interleaved power converters, and practical aspects such as protection and thermal management. Filling the gap between textbooks and technical papers, his book offers practical
solutions to current industrial demands with a focus on the particular business needs of performance quality and cost efficiency. It also serves as an excellent textbook for graduate

Описание: This book introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. Benefit to the reader includes: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters.
