Design of Magnetic Components for Switched Mode Power Converters

Mathematical Analysis approach to the design of transformers used in Switched Mode Power Converters (SMPCs). Various design aspects and many practical examples are covered in the book. The design techniques illustrated in the book have been tested at CEDT over the past several years.

The book contains a Mathematical analysis of the various transformer topologies encountered in switched mode power converters. Design of Inductors and current transformers are also treated in detail. Included also are the various care materials and types that are commonly used in SMPCs. This book also introduces the reader to Computer aided design of transformers.

The book would be of immense use to design engineers in the electronic/electrical industry, senior undergraduate and graduate students and faculty of electronic and Electrical engineering.
