Efficient Power Conversion (EPC) has recently introduced two new, 100V, GaN devices that are able to handle 48V server and automotive needs. I will be examining the 48V server power solutions to the processor as well as in automotive and energy storage systems (See my article Bi-directional DC/DC power supplies: Which way do we go?) bi-directional supplies, in an EDN exclusive article coming up in the near future. GaN power transistors MUST be a part of these kinds of architectures; from my point-of-view there is no better alternative.
In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN ...
With the power architecture transition from a 12 V to a 48 V bus power distribution in modern data centers, there is an increased demand to improve 48 V power conversion efficiency and power density. In this context, DC-DC converters designed using eGaN® FETs and ICs provide a high efficiency and high power density solution. Additionally, with the advent of 48 V power systems in mild-hybrid, hybrid and plug-in hybrid electric vehicles, GaN transistors can provide a reduction in size, weight, and Bill of Materials (BOM) cost.

In this video Alex Lidow, Founder and CEO of EPC, talks to Alix Paultre, Editor-in-Chief of Power Electronics News, about the various demonstrations of GaN-based solutions at the EPC booth at APEC 2018 in San Antonio, Texas. The high-frequency operation and other advanced performance advantages over Silicon enables GaN to empower applications from LIDAR to wireless power transmission. The booth exhibits include examples of these, from a real-time LIDAR demonstration to a running "wireless desk".
