Wireless Power Transfer Technologies: Theory and technologies

Wireless Power Transfer (WPT) serves to transfer power from a grid or storage unit to a device without the need for cable connections. This can be performed by induction, as well as by using radio or microwaves.

The technology is already seeing widespread use; for example, for charging of cell phones and toothbrushes. R&D of WPT, especially inductive and resonance coupling WPT, has been active over recent years. The increased need to decarbonize the transport sector in particular is resulti...
