Electrical Machines, Drives, and Power Systems for electrical engineering and electronics engineering students free download

For courses in Motor Controls, Electric Machines, Power Electronics, and Electric Power. This best-selling text employs a theoretical, practical, multidisciplinary approach to provide introductory students with a broad understanding of modern electric power. The scope of the book reflects the rapid changes that have occurred in power technology over the past few years?allowing the entrance of power electronics into every facet of industrial drives, and expanding the field to open more career opportunities. NEW?Doubly-fed induction machine properties and behavior?For use as a wind turbine generator to produce electricity. Pulse-width modulation (PWM) modifications. Direct Torque Control (DTC) coverage. Wind power and the use of turbines. The HVDC Light? method of transmitting electric power. One advantage of this broad-based book is that knowledge gained in one sector (such as motor drives) becomes useable in an entirely different sector (such as transmission lines).

Another important feature of my book is the simple mathematical expressions that describe the behavior of rotating machines, transformers, transmission lines and power electronics. Despite their simplicity, the expressions are eminently practical and useful. They enable you to make meaningful calculations using a pocket calculator or a favored computer program. And all you need is a knowledge of simple algebra and elementary trigonometry.

But the basic principles of electric motors and transformers, the workhorses of industry, have not changed during that time. Also, the electronic drives described in the book have reached a stage of sophistication that can only be improved by the development of better thyristors, transistors, IGBTs and other switching devices. Consequently, the basic principles of electronic drives and power systems, as described and explained in the 6th edition of Electrical Machines, Drives, and Power Systems, will also remain essentially the same. Having said this, the new editions have the advantage of reflecting the latest concepts that are of lasting importance. These fundamental observations have strongly influenced the structure and selection of the topics in my book. The descriptive title - Electrical Machines, Drives and Power Systems - implies three major fields of interest. It has been my privilege to work in these fields, and to follow their development, for over 50 years.
I hope this introduction to the technical and philosophical aspects of Electrical Machines, Drives, and Power Systems will induce you to buy it, keep it, and consult it to meet your future needs.
