Wireless Charging

Wireless Charging Using GaN Transistors

Charge pads can now charge multiple wireless devices simultaneously thanks to gallium-nitride FETs. In this short demo, WTWH Media’s Lee Teschler interviews 氮化镓系统 (GaN Systems)’ Jim Witham who described a 70-W charging pad built by Gill Electronics to the AirFuel standard that has a two-inch throw. This feat is made possible only through the use of GaN semiconductors able to switch at AirFuel’s 6.78 MHz frequency standard.
