Wireless/Contactless Power Transfer

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 ...
