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.
