  • The use of a combustion engine to motivate a car has been questioned in recent times due to the increasing concern of warming. As a result of this, the concept of driving a car with an electric engine has become of particular interest. Dr. Geoff Walker and his PhD students are working on the creation of the Universitys own electric car. This thesis project is focused on deriving a control scheme to drive an induction machine that could be applied to the electric car.

  • Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment.

  • This book is mainly intended for designers and users of magnetic components in power electronics. It can also be used for didactical purposes. Magnetic components such as inductors and transformers constitute together with the control and the semiconductor components, the main parts in the design of power electronic converters. Some experience teaches that the design of the magnetic parts is still often done by trial and error. This can be explained by a (too) long working-in time for designing inductors and transformers.

  • The Toyota Motor Corporation was founded in 1937 by Kiichiro Toyoda. It originally started as a subsidiary of his father’s company Toyoda Industries. The first vehicle, the Toyota AA, was produced in 1936 whilst the company was still associated with Toyoda. The brand as we know it became established as an independent company in 1937 and changed their name to Toyota. The name change was implemented to signify a separation of work and home, to simplify the pronunciation and because it only took 8 brush strokes (which is considered lucky) to write in Japanese.

  • An Introduction to Electric Circuits is essential reading for first year students of electronics and electrical engineering who need to get to grips quickly with the basic theory. This text is a comprehensive introduction to the topic and, assuming virtually no knowledge, it keeps the mathematical content to a minimum. As with other textbooks in the series, the format of this book enables the student to work at their own pace. It includes numerous worked examples throughout the text and graded exercises, with answers, at the end of each section....

  • I have been undertaking the research and practical applications of power system optimization since the early 1980s. In the early stage of my career, I worked in universities such as Chongqing University (China), Brunel University (UK), National University of Singapore, and Howard University (USA). Since 2000 I have been working for AREVA T & D Inc (USA). When I was a full - time professor at Chongqing University, I wrote a tutorial on power system optimal operation, which I used to teach my senior undergraduate students and postgraduate students in power engineering until 1996.

  • I enjoyed reading this book for a number of reasons. One reason is that it addresses high-speed analog design in the context of microwave issues. This is an advanced level book, which should follow courses in basic circuits and transmission lines. Most analog integrated circuit designers in the past worked on applications at a low enough frequency that microwave issues did not arise. As a consequence, they were adept at lumped parameter circuits and often not comfortable with circuits where waves travel in space.

  • The purpose of these notes is be used to introduce Electrical Engineering students to Electrical Machines, Power Electronics and Electrical Drives. They are primarily to serve our students at MSU: they come to the course on Energy Conversion and Power Electronics with a solid background in Electric Circuits and Electromagnetics, and many want to acquire a basic working knowledge of the material, but plan a career in a different area (venturing as far as computer or mechanical engineering).

  • Logic Pro 9 is arguably the best and most complete version of Logic ever, which meant we had our work cut out for us! Thank God for co-writer Kevin Anker. He really took this project by the horns, and this revision would not be half of the book that it is without Kevin’s writing and organizing skills! As ever, I couldn’t do anything without the unwavering support of my wife, Michelle, my mother, and in the recent past, my late father, grandfather, and grandmother. I would also like to thank Dr.

  • When talking about modelling it is natural to talk about simulation. Simulation is the imitation of the operation of a real-world process or systems over time. The objective is to generate a history of the model and the observation of that history helps us understand how the real-world system works, not necessarily involving the real-world into this process. A system (or process) model takes the form of a set of assumptions concerning its operation.

  • Atomic models of the myosin motor domain with different bound nucleotides have revealed the open and closed con-formationsof the switch2 element [Geeves,M.A.&Holmes, K.C. (1999)Annu. Rev. Biochem.68, 687–728]. The two conformations are in dynamic equilibrium, which is con-trolled by the bound nucleotide. In the present work we attempted to characterize the flexibilityof themotor domain in the open and closed conformations in rabbit skeletal myosin subfragment 1.
