Magnetic Components Design and Applications is intended primarily for the circuit designer and the power processing systems designer who have found that in order to be more effective they must learn not only to use, but to design their own magnetic components. It will also be useful to the trans­ former engineer, by showing how to develop high-performance designs quickly and easily by employing optimization criteria. This book is a design manual, a how-to-build-it manual, and a survey of some common and state-of-the-art practices in magnetic component design and high voltage insulation. It contains the data necessary to design power transformers on a gradient scale from 60 Hz to several hundred kilohertz, conventional and air-core current transformers, power reactors, saturable transformers and saturable reactors, and air core and conventional pulse transformers. Further, it con­ tains essential information about dielectric materials and fabrication meth­ ods, basic heat transfer technology, and electric field gradient control for high voltage applications. Mathematical methods of optimization are developed, and results are given in a number of areas, particularly in the area of maximizing power den­ sity in power transformers and the maximization of stored energy per unit volume for power reactors. For various reasons, each chapter is written from a different starting level.
