Wireless Power
Multiple Device, Large-Surface-Area Power Made Easy

Wireless power that covers a large surface area enables devices like robots, vacuums, eScooters, and eBikes to recharge without needing a precise alignment. This technology is innovative, especially in the way it can recharge drone batteries. By placing mid-air recharging stations along the drone's route, drones can recharge their batteries without having to land. These stations are equipped with wireless charging antennae, providing a seamless recharging experience.

Wireless power includes resonant, capacitive, and high-power inductive technologies. The high switching capability of GaN, along with the small size can be used to create compact wireless power transmitters for all these charging systems.
