For the first time in power electronics, this comprehensive treatment of switch-mode DC/DC converter designs addresses many analytical closed form equations such as duty cycle prediction, output regulation, output ripple, control loop-gain, and steady state time-domain waveform. Each of these equations are given various topologists and configurations, including forward, flyback, and boost converters. Pulse Width Modulated DC/DC Converters begins with a detailed approach to the quiescent operating locus of a power plant under open-loop. The reader is then led through other supporting circuits once again in the quiescent condition. These exercises result in the close-loop formulations of the subject system, providing designers with the ability to study the sensitivities of a system against disturbances. With the quiescent conditions well established, the book then guides the reader further into the territories of system stability where small signal behaviors are explored. Finally, some important large signal time-domain studies cap the treatment. Some distinctive features of this book include: *detailed coverage of dynamic close-loop converter simulations using only personal computer and modern mathematical software *Steady-state, time-domain analysis based on the concept of continuity of states Voltage-mode and current-mode control techniques and their differences of merits A detailed description on setting up different equations for DC/DC converters'simulation using only PC

Scientists and engineers around the world are striving to develop new sources of energy. One source, ocean thermal energy conversion, has virtually unlimited potential. It is based on techniques that exploit heat produced by solar energy that may, in turn, be used to produce fuel and electricity. This book reviews the status and background of this promising technology. William H. Avery is the leading expert in this field, and his co-author Chih Wu is an authority on heat engine performance. Together they describe the workings of an OTEC power plant and how such a system might be implemented as part of a futuristic national energy strategy. The book is the only detailed presentation of basic OTEC technology, its testing and improvement. It is based on extensive development initiatives undertaken internationally during the period from 1974 through 1985. The book offers a thorough assessment of the economics of OTEC in comparison with other energy production methods. It will be of interest to a wide range of professionals in energy research, power and mechanical engineering, and to upper-level undergraduate students taking courses in these fields.

This book and the accompanying computer software are intended to enhance and streamline the study of the field of thermodynamics. The package is design and problem-solving oriented. Released from the drain of repetitive and iterative hand calculation, students can be led to a far wider and deeper study than has been possible previously.

Finite-time thermodynamics (FTT) is one of the newest and most challenging areas in thermodynamics. The objective of this book is to provide results from research, which continues at an impressive rate. The authors make a concentrated effort to reach out and encourage academic and industrial participation in this book and to select papers that are relevant to current problems and practice. The numerous contributions from the international community are indicative of the continuing global interest in finite-time thermodynamics. All represent the newest developments in their respective areas.

Heat engines that use gases as the working fluid in a closed system model were discussed in this book. Otto cycle, Diesel, Miller, and Dual cycle are internal combustion engines. Stirling cycle is an external combustion engine. The Otto cycle is a spark-ignition reciprocating engine made of an isentropic compression process, a constant volume combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio. The compression ratio is defined as r=Vmax/Vmin. The Otto cycle efficiency is limited by the compression ratio because of the engine knock problem. The Diesel cycle is a compression-ignition reciprocating engine made of an isentropic compression process, a constant pressure combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio and cut-off ratio. The compression ratio is defined as r=Vmax/Vmin. The cut-off ratio is defined as rcutoff=Vcombustion off/Vmin. The Dual cycle involves two heat addition processes, one at constant volume and one at constant pressure. It behaves more like an actual cycle than either Otto or Diesel cycle. The Lenoir cycle was the first commercially successful internal combustion engine. The Stirling cycle and Wicks cycle are attempt to achieve the Carnot efficiency. The Miller cycle uses variable valve timing for compression ratio control to improve the performance of internal combustion engines.
