Wireless/Contactless Power Transfer: - Capacitively coupled solutions
by:Chao Liu, Aiguo Patrick Hu
For decades, people have been trying to develop wireless/contactless power transfer technologies to drive movable loads without direct electrical contacts, with ICPT (Inductively Coupled Power Transfer) being the most popular. As a new alternative, CCPT (Capacitively Coupled Power Transfer), which employs electric field (rather than magnetic field)...
For decades, people have been trying to develop wireless/contactless power transfer technologies to drive movable loads without direct electrical contacts, with ICPT (Inductively Coupled Power Transfer) being the most popular. As a new alternative, CCPT (Capacitively Coupled Power Transfer), which employs electric field (rather than magnetic field) coupling, has drawn a great attention recently due to its inherent advantages of confined electric field between the coupling plates, power transfer capability through metal barriers, very low eddy current power losses associated with metal surroundings, and reduced circuit sizes/costs, etc. This book is about a fundamental study on CCPT technologies covering full mathematical analysis, detailed computer simulation, and practical experiments of different types of CCPT systems. The results obtained demonstrate the feasibility and potential of CCPT as an emerging wireless/contactless power transfer solution; and the theory and practical design methods established lay a solid foundation for future CCPT research and development.
Since launching the first textbook rental site in 2006, BookRenter has never wavered from our mission to make education more affordable for all students. Every day, we focus on delivering students the best prices, the most flexible options, and the best service on earth. On March 13, 2012 BookRenter.com, Inc. formally changed its name to Rafter, Inc. We are still the same company and the same people, only our corporate name has changed.
