This book is intended to explain the technical principles involved in the many AC variable speed drive systems available today. It deals with all the DC link inverter and direct AC to AC converter systems that are in commercial use. The principles of AC motors are considered specifically from the variable frequency point of view, and this chapter concentrates on the effects of harmonics. The different types of power semiconductor switches are considered separately from the drive systems in which they are used.

This book is a guide to the whole field of high voltage insulators as used in electrical power networks, traction and production. It covers the historical development of the shapes - sometimes strange ones - of modern types, decribes the principal materials - both ceramic and polymeric - and their fabrication, explains the physical principles of contamination and flashover, and reviews the mass of data on research and testing.

The aim has been to provide an up-to-date analysis of the theoretical and practical problems involved in circuit breaker design. Circuit breakers present very special design problems because of the wide mixture of experience required.
Designers need to have an understanding of the parameters of power systems in which circuit breakers have a duty; of the physics of the arc produced during the interrupting process; of electrical engineering which is concerned with the insulation co-ordination and design problems; of mechanical engineering on which the performance and reliability of the operation of the circuit breaker depend; and of the need to meet cost-effective criteria.

Introduction to Solid Modeling using SolidWorks primarily consists of chapter-long tutorials, which introduce both basic concepts in solid modeling (such as part modeling, drawing creation, and assembly modeling) and more advanced applications of solid modeling in engineering analysis and design (such as mechanism modeling, mold creation, sheet metal bending, and rapid prototyping). Each tutorial is organized as “keystroke-level” instructions, designed to teach the use of the software.

This monograph deals with theoretical aspects and numerical simulations of the interaction of electromagnetic fields with nonlinear materials. It focuses in particular on media with nonlinear polarization properties. It addresses the direct problem of nonlinear Electrodynamics, that is to understand the nonlinear behavior in the induced polarization and to analyze or even to control its impact on the propagation of electromagnetic fields in the matter.
