What GaN circuits can do for wireless charging

In this short video, EPC's Alex Lidow explains why GaN FETs may make it possible to wirelessly charge a variety of vehicles, including flying drones. Wireless charging circuits employing GaN FETs work at 13.56 MHz, a switching frequency difficult to reach with ordinary silicon FETs. The GaN transistors used are also five to ten times smaller than silicon devices able to handle the same power levels.
