Book Description
This is the first definitive treatment of an analytically complex type of electric power converter (cycloconverter) operating between ac sources and loads, where the output frequency can be independently controlled from the input frequency. Currently, there is much interest in applying cycloconverters to the special control of ac motors and to aircraft electrical systems; however, progress has been limited by lack of good technical information. This book provides an immeasurable service in that the author's theory is sufficiently detailed to allow accurate performance evaluation, design calculations, and cost projections. Moreover, he has culled an extensive, coherent bibliography from the scattered literature in the field. A cycloconverter of the naturally commutated type is essentially a pair of phase-controlled rectifiers connected in inverse parallel. Modulation of these converters to provide ac power at a lower frequency than the source frequency greatly complicates the analysis of their behavior. McMurray treats various effects of the modulation in theoretical detail and shows how the resulting equations can be used for accurate performance and design calculations. His analysis of the cycloconverter is based on the classical equations of a phase-controlled rectifier operating with continuous load current. The general algebraic form of the equations, which are applicable to many different circuit configurations, is retained throughout the book. It also presents in tabular and graphical form the results of numerical integration of corresponding rectifier equations, required in calculating many cycloconverter performance factors. This is the fourth monograph in the series Modern Electrical Technology, edited by Alexander Kusko.

Book Description
Power electronics, which is a rapidly growing area in terms of research and applications, uses modern electronics technology to convert electric power from one form to another, such as ac-dc, dc-dc, dc-ac, and ac-ac with a variable output magnitude and frequency. Power electronics has many applications in our every day life such as air-conditioners, electric cars, sub-way trains, motor drives, renewable energy sources and power supplies for computers. This book covers all aspects of switching devices, converter circuit topologies, control techniques, analytical methods and some examples of their applications.* 25% new content* Reorganized and revised into 8 sections comprising 43 chapters* Coverage of numerous applications, including uninterruptable power supplies and automotive electrical systems* New content in power generation and distribution, including solar power, fuel cells, wind turbines, and flexible transmission

Book Description
Alternating current (AC) induction and synchronous machines are frequently used in variable speed drives with applications ranging from computer peripherals, robotics, and machine tools to railway traction, ship propulsion, and rolling mills. The notable impact of vector control of AC drives on most traditional and new technologies, the multitude of practical configurations proposed, and the absence of books treating this subject as a whole with a unified approach were the driving forces behind the creation of this book. Vector Control of AC Drives examines the remarkable progress achieved worldwide in vector control from its introduction in 1969 to the current technology. The book unifies the treatment of vector control of induction and synchronous motor drives using the concepts of general flux orientation and the feed-forward (indirect) and feedback (direct) voltage and current vector control. The concept of torque vector control is also introduced and applied to all AC motors. AC models for drive applications developed in complex variables (space phasors), both for induction and synchronous motors, are used throughout the book. Numerous practical implementations of vector control are described in considerable detail, followed by representative digital simulations and test results taken from the recent literature. Vector Control of AC Drives will be a welcome addition to the reference collections of electrical and mechanical engineers involved with machine and system design.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.
