Wireless Power Transfer (WPT)
enables power to be transferred from a grid or storage unit to a device
without the need for cable connections. This can be performed by
inductive coupling of magnetic fields as well as by direct radiative
transfer via beams of electromagnetic waves, commonly radiowaves,
microwaves or lasers. Inductive coupling is the most widely used
wireless technology with applications including charging handheld
devices, RFID tags, chargers for implantable medical devices, and
proposed systems for charging electric vehicles. Applications of
radiative power transfer include solar power satellites and wireless
powered drone aircraft.
This book covers the very latest in
theory and technology of both coupling and radiative wireless power
transfer. Topics covered include the basic theory of inductive coupling
and resonance coupling WPT; multi-hop WPT; circuit theory for wireless
couplers; inverter/ rectifier technologies for WPT systems; basic theory
of WPT via radio waves; technologies of antenna and phased array for
WPT via radio waves; transmitter/rectifier technologies for WPT via
radio waves; applications of coupling WPT for electric vehicle charging;
applications of long-distance WPT; and biological interactions of
electromagnetic fields and waves.
