In past postings , we looked at the applications that have emerged because of new capabilities available with #GaN technology. We also discussed the transformational nature of some of these applications in areas like medicine, telecommunications,human-machine interfaces, and the delivery of electrical power itself (wireless power transfer). GaN technology is entering an era similar to the 80’s and 90’s when the utility of technological improvement was apparent across broad commercial markets. Consequentially, consumers will be willing to pay a premium for the life-style improvements enabled by these improvements thereby accelerating growth of GaN applications for the foreseeable future.

The contribution that gallium nitride semiconductor technology is making in medical applications can be measured not only in dollars saved, but also more importantly in its contribution to the speed of intervention, diagnostic accuracy and patient comfort. Because of its superior performance and small size, GaN components (FETs and ICs) are enabling end applications such as wireless power charging, higher resolution diagnostics, and precision surgical robotics. These applications are improving ways health care is being provided.

As the VP of Sales and Marketing for EPC, I have attended a number of power electronics industry trade shows since the beginning of the year. What has struck me about these shows is the increasing number of end product demonstrations enabled by GaN FET and IC technology.

At CES in January, APEC in March, PCIM Europe in May, and most recently, at Computex Asia last month, GaN applications were front and center. Here are a few examples of what I saw:

In March 2010 Efficient Power Conversion (EPC) proudly launched our GaN technology at the CIPS conference in Nuremberg, Germany.  Parts and development kits were readily available off-the shelf and therefore designers could immediately get started with a new state-of-the-art semiconductor technology.

At that time, we listed four key attributes we believed a new semiconductor technology needed in order to be really disruptive to the end markets.  A lot has happened in the six years since.  GaN has continued to ascend as the presumptive replacement for the aging power MOSFET, yet there are still a few design engineers and technical managers that remain skeptical.  So let’s look again at these four key attributes and see where GaN stands in addressing them.
