Sneak Circuits of Power Electronic Converters
Sneak Circuits of Power Electronic Converters
Work on sneak circuits and related analysis methods for power converters contributes to the reliability of power electronic systems worldwide. Most books on the subject focus on electronic systems; this book is perhaps the first to examine power electronic systems. The authors describe sneak circuit phenomena in power converters, introduce SCA methods for power electronic systems, and propose how to eliminate and make use of sneak circuits.
This book:
* highlights the advanced research works in sneak circuit analysis by a leading author in the field
* is original in its treatment of power electronics converters, going beyond the electronic system level
* is suitable for both introductory and advanced levels
* offers guidelines for industry professionals involved in the design of power electronic systems, enabling early detection of potential problems
This book is geared for researchers and graduate students in electrical engineering, as well as engineers and researchers in power electronics. Researchers in power electronics reliability will also find it to be a helpful resource.
