Educational Videos on GaN Devices for Power Conversion

Efficient Power Conversion Corporation (EPC) has expanded its video library on GaN technology with the addition of a nine-part educational video series designed to provide power system design engineers advanced technical information and application examples on how to design more efficient power conversion systems using gallium nitride-based transistors and integrated circuits.

Beyond giving the design basics for using GaN transistors and reliability information, this video series provides direction on converting development boards into working prototypes. Further, the series offers practical examples on the use of GaN transistors in widely used power electronics applications such as dc-dc conversion for telecom and datacom systems, as well as two videos on the use of GaN devices in wireless charging systems.

"This series of short, less than ten-minute each, videos will assist designers of power conversion systems increase their understanding of state of the art in power conversion as well as the role played by GaN technology. These videos will accelerate their learning curve and increase their ability to take maximum advantage of the high switching frequency and high performance of GaN power transistors," noted Alex Lidow, CEO and co-founder of EPC.

Gallium Nitride (GaN) Advanced Learning Video Series: GAL01: What is GaN? GaN has emerged as a displacement technology to silicon solutions. GaN's superior performance can be implemented at the price of silicon, which makes it ideal for power conversion system. GAL02: Design Basics Gate drive requirements for use with eGaN® FET and current power conversion circuit designs. GAL03: GaN is Reliable EPC reliability testing has demonstrated that GaN technology is ready for commercial use and this video describes the reliability tests and the results achieved. GAL04: 500 W Isolated DC-DC Converter with GaN The Power of a Quarter Brick in the Size of an Eight Brick Presentation of a fully regulated, fully isolated 500 W 1/8th brick using eGaN transistors enabling a 60% increase in power in the industry standard DOSA footprint.

GAL05: Cut the Cord! Wireless Power with GaN Demonstrations of the benefits of GaN technology in resonant wireless power transfer systems. Both AirFuel Alliance's class 2 and class 3 system designs are showcased as examples. GAL06: eGaN® IC's Integrate for Even Higher Efficiency in Wireless Power and DC-DC Conversion Integration further widens the efficiency gap between eGaN technology and traditional silicon. Integrated devices save space, improve efficiency, and lower system costs. GAL07: Increase Power Density with GaN Discussion of techniques, including thermal management, for obtaining the most benefit from using GaN technology in power conversion applications. GAL08: How to Turn a Development Board into a Working Prototype A practical guide on turning a standard EPC half-bridge development board into a working prototype system.

GAL09: Where is GaN Going? In this final video in the series, EPC CEO and Co-founder, Alex Lidow, discusses the wide variety of applications enabled by GaN technology that are "changing the way we live." Emerging applications such as autonomous vehicles, wireless power transfer, augmented reality, and envelope tracking take advantage of this game changing technology.
