Wireless Charging

Expanding battery functioned consumer electronics devices coupled with growing preference for hassle free charging solutions are accelerating the demand for wireless charging solutions.  Wireless power transfer, popularly known as wireless charging, is as technology that enables transmits electromagnetic energy from power source to an electrical load through air gap, Wireless charging is user friendly technology that finds applications ranging from mobile devices to electric car.

Inductive coupling and coupled magnetic resonance and electromagnetic radiation are the three wireless power transfer (WPT) technologies. The inductive coupling wireless charging technology is the widely adopted technology with close to 50% of market share, as the power stability of wireless chargers using this technology is high compared to other wireless charging technologies.

Wireless Chargers – Standards

AirFuel Alliance is an authority on wireless power technology and standards, formed by merger of Alliance for Wireless Power (A4WP) and Power Matters Alliance (PMA) in 2015.
