Power Circuits and Electromechanics, 2nd Edition

Authors: K. R. Davis and M. A. Pai

ISBN: 978-1-64617-334-1

This book is intended to serve as a one semester introductory course to the power area, to help students build a foundation in power systems, power electronics, and electric machines based upon power circuits and electromechanical energy conversion. The students should have basic exposure to KCL, KVL and simple circuits as well as a course in field theory or electromagnetism before taking this course. The book is basically in three modules.

The first module covers phasors, complex power in single and three phase circuits, power electronics converters, analysis of magnetic circuits, mutually coupled circuits and single phase transformers.

The second module, drawing upon the quasi-static approximation of magnetic field equations, develops the concepts of electromechanical energy conversion, forces of electric origin leading to the dynamics equations of motion of the electromechanical system. A brief introduction to state space modeling, static equilibrium and stability is included. 

The third module discusses the energy and co-energy framework, the torque of electric origin in synchronous, induction and DC machines, and a brief discussion of single phase motors. In each case, the equivalent circuit for the machine for steady state operation is developed for analysis purposes. The book concludes with several examples of application areas and emerging topics in future electric energy systems.
