Consumer Electronics GaN Applications: Wireless Power

From Small to Large-Surface-Area, Multiple-Device Power Made Easy

Wireless power is ready to be incorporated into our daily lives. Already on the market are 1:1 TX/RX charging solutions for various devices such as cell phones, wearables, hearables, and IoT. Transmitters can be placed in furniture, walls, floors, to efficiently and economically power or charge our electronic and electrical devices over large areas and to multiple devices.

Magnetic resonance technology is the key to ubiquitous implementation – enabling large surface area transmission, spatial freedom for placement of receiving devices, and the ability to power multiple devices simultaneously.

The high switching capability of GaN enables efficient multi-megahertz operation required for magnetic resonance transmission. This along with the small size can be used to create compact wireless power transmitters at low cost.
