The first treatment of advanced knowledge of electricalsneak circuits and its analysis method in powerelectronics
The work on sneak circuit and its analysis methods for powerconverters contributes to the reliability of power electronicsystems worldwide. Most books in the subject concentrate onelectronic systems, but this book is perhaps the first to examinepower electronic systems. It describes the sneak circuitphenomena in power converters, introduces some SCA methods forpower electronic systems and proposes how to eliminate and make useof sneak circuits. The book is divided into three separatesections. Firstly, the sneak circuit paths and sneak circuitoperating conditions are discussed in different kinds of powerconverters, including resonant switched capacitor converters, basicDC-DC converters, soft-switching converters and Z-sourceconverters; Secondly, the sneak circuit analysis guidelinesfor power converters based on generalized matrix, adjacency matrixand Boolean matrix are presented respectively; Thirdly, thesneak circuit elimination techniques are introduced and verified inseveral power converters, with applications of sneak circuitsdescribed in conclusion. Written by a lead author withextensive academic and industrial experience, the book provides acomplete introduction and reference to students and professionalsalike.
Contents include: Fundamental Concepts, SCA of Resonant SwitchedCapacitor Converters, SC of DC-DC Converters, SC Analysis Method(including Boolian Matrix), and Applications of SC in PowerConverters.
* Highlights the advanced research works in the sneak circuitanalysis, by a leading author in the field
* Original in its treatment of power electronics converters; mostother books concentrating on electronics systems, and aimed at bothintroductory and advanced levels
* Offers guidelines for industry professionals involved in thedesign of power electronic systems, enabling early detection ofpotential problems
Essential reading for Graduate students in ElectricalEngineering: Engineers and Researchers in Power Electronics
