Wireless power applications are gaining popularity in many commodity products such as mobile phones chargers. Enhancement mode gallium nitride transistors offer an alternative to MOSFET technology as they can switch fast enough to be ideal for wireless power applications. This article focuses on experimental evaluation of an induction coil wireless energy system using eGaN FETs operating at 6.78 MHz designed to be suitable for multiple 5 W USB based charging loads.
