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.

In this article, we show that using GaN Transistors such as Efficient Power Conversion’s eGaN® FETs can improve the efficiency of isolated eighth brick DC-DC converters. This type of power converters is used extensively in mainframes, servers and telecommunication systems, and is available in a variety of sizes, output power capability, and input and output voltage ranges. Its modularity, power density, reliability and versatility have simplified the isolated power supply market.
