Product Description

This book collates the information available on this topic, hitherto only to be found in journals and at conferences. It presents the fundamentals and advances in average and small-signal modeling of switched-mode converters, before applying this information to generate a real canonical converter model. Practical examples are scattered throughout the text, and experimental evidence is cited to support theoretical findings.

The result is a solid basis for understanding and utilizing the dynamics of switched-mode converters -- for the first time in their 40-year history.

From the Back Cover

This book provides information which is essential for designing high quality switched-mode converters, understanding the origin of the problems usually encountered in the practical applications, and avoiding them. It presents the fundamentals of the dynamic characterization of switched-mode converters applicable for individual converters and interconnected systems composed of them, as well as useful detailed information on specific design topics. The theoretical findings are validated with experimental evidence. A comprehensive list of references is provided at the end of each chapter.
