Electrical drives convert in a controlled manner, electrical energy into mechanical energy. Electrical drives comprise an electrical machine, i.e. an... electro-mechanical energy converter, a power electronic converter, i.e. an electrical-to-electrical converter, and a controller/communication unit. Today, electrical drives are used as propulsion systems in high-speed trains, elevators, escalators, electric ships, electric forklift trucks and electric vehicles. Advanced control algorithms (mostly digitally implemented) allow torque control over a high-bandwidth. Hence, precise motion control can be achieved. Examples are drives in robots, pick-and-place machines, factory automation hardware, etc. Most drives can operate in motoring and generating mode. Wind turbines use electrical drives to convert wind energy into electrical energy. More and more, variable speed drives are used to save energy for example, in air-conditioning units, compressors, blowers, pumps and home appliances. Key to ensure stable operation of a drive in the aforementioned applications are torque control algorithms. In Advanced Electrical Drives, a unique approach is followed to derive model based torque controllers for all types of Lorentz force machines, i.e. DC, synchronous and induction machines. The rotating transformer model forms the basis for this generalized modeling approach that ultimately leads to the development of universal field-oriented control algorithms. In case of switched reluctance machines, torque observers are proposed to implement direct torque algorithms. From a didactic viewpoint, tutorials are included at the end of each chapter. The reader is encouraged to execute these tutorials to familiarize him or herself with all aspects of drive technology. Hence, Advanced Electrical Drives encourages “learning by doing”. Furthermore, the experienced drive specialist may find the simulation tools useful to design high-performance controllers for all sorts of electrical drives.

This textbook follows the treatment of electric machines and drives in my earlier textbook "Electric Drives – An Integrative Approach." I have... attempted to use the same notation to provide consistency. If I am asked to list three unique features of this book, the following are foremost in my opinion: Keeping it simple without being simplistic, Avoiding unnecessary mathematics, and Providing a “physical” picture as much as possible for visualization purposes. The third item above needs elaboration. Most research literature and textbooks in this field treat dq-axis transformation of a-b-c phase quantities on a purely mathematical basis, without relating this transformation to a set of windings that could be visualized. The approach adopted in this book is different but leads to the same results - we visual a set of representative dq windings along an orthogonal set of axes and then relate their currents and voltages to the a-b-c phase quantities. This discussion follows seamlessly from the treatment of space vectors and the equivalent winding representation in steady state in the previous course. For discussion of all topics in this course, computer simulations are a necessity. For this purpose, I have chosen Simulink® for the following reasons: a student-version that is more than sufficient for our purposes is available at a very reasonable price and it takes extremely short time to become proficient in its use. Moreover, this software simplifies the development of a real-time controller of drives in the hardware laboratory for student experimentation – such a laboratory, using 42-V (a future standard for automotive voltages) machines, is at present under development using a digital signal processor based rapid-prototyping tool. All chapters in this book can be covered in a single-semester course. The MATLAB® and the Simulink® files used in examples are included on a cd-rom attached to this book. The reader is urged to first look at the read-me file on this cd-rom before reading this textbook.

As in the First Edition, each chapter in this new Second Edition is authored by one or more acknowledged experts and then carefully edited to ensure a... consistent level of quality and approach throughout. There are new chapters on passive devices, RF and microwave packaging, electronic package assembly, and cost evaluation and assembly, while organic and ceramic substrates are now covered in separate chapters. All the hallmarks of the First Edition, which became an industry standard and a popular graduate-level textbook, have been retained.An Instructor's Manual presenting detailed solutions to all the problems in the book is available upon request from the Wiley Makerting Department.

The foundation for EMS education was established in 1971 when the American Academy of Orthopaedic Surgeons (AAOS) authored the first emergency medical... technician textbook. Since then, the AAOS has set the gold standard for EMS training programs with the Orange Book Series. This Second Edition, based on Intermediate Emergency Care and Transportation of the Sick and Injured, raises the bar even higher with world-class medical content and innovative instructional resources that meet the diverse needs of today s educators and students. Based on the new National EMS Education Standards for Advanced Emergency Medical Technician, the Second Edition offers complete coverage of every competency statement with clarity and precision in a concise format that ensures student comprehension and encourages critical thinking. New cognitive and didactic material is presented, along with new skills and features, to create an innovative AEMT training solution. Topics including advanced pathophysiology, acid-base balance, fluids and electrolytes, intravenous therapy, intraosseous access, blood glucose monitoring, and administration of AEMT-level medications tailor this textbook to the new Advanced EMT level. Additional online skills allow this textbook to be customized for every AEMT training program s unique needs. Current, State-of-the-Art Medical Content Advanced Emergency Care and Transportation of the Sick and Injured, Second Edition incorporates up-to-date, evidence-based medical concepts to ensure that students are taught assessment and treatment modalities that will help patients in the field today. Advanced Pathophysiology Advanced Emergency Care and Transportation of the Sick and Injured, Second Edition provides a solid foundation in pathophysiology one of the key knowledge areas required to become a successful Advanced EMT. Patient Assessment This Second Edition teaches and reinforces the concept of Patient Assessment with a single, comprehensive chapter, ensuring that students understand patient assessment as a single, integrated process the way that providers actually practice it in the field. Each medical and trauma chapter reinforces the patient assessment process by highlighting the unique aspects of the illness or injury. Clear Application to Real-World EMS Through evolving patient case studies in each chapter, the Second Edition offers students a genuine context for the application of the knowledge presented in the chapter. This approach makes it clear how all of the information will be used to help patients in the field.
