APEC 2018: GaN Revolution in the World of Power Electronics

Wed, 28 Feb 2018 19:15:00 GMT

Come see the world’s smallest, most efficient, and lowest cost DC-DC converters! eGaN technology makes this, and much more possible and will be on full display at this year’s American Power Engineering Conference, APEC, where power engineers from around the world gather to see and learn about the latest innovations and products available in the world of power electronics.

EPC GaN experts will be presenting a half-day educational seminar on the state of GaN technology and its application to leading-edge power electronics. In addition, EPC will deliver six technical sessions, as well as demonstrate eGaN applications in our booth and customer suite.

Join EPC at CES 2018

Mon, 01 Jan 2018 20:25:00 GMT

We are quite excited about this year’s CES being held in Las Vegas from January 9th through the 12th. Our excitement is grounded in the fact that we will be showing the power of GaN technology in two locations – within the AirFuel™ Alliance booth at the Sands Hotel and in our hospitality suite at the Venetian hotel!

Nobody Likes Power Cords! Wireless Power is Happening

Sun, 01 Oct 2017 00:43:00 GMT

I have yet to meet someone who likes power cords.

Take for example Keith. In figure 1 is a photo of all the power-related accessories Keith lugs around in his backpack to make certain he will be able to run his phone, tablet, and computer wherever he goes. What Keith and others may not realize is that the technology is available that can eliminate every one of these cords – today! So, why is it taking so long for wireless power solutions to become a household technology?

Certainly, wireless charging is not a new topic having been talked about for quite a while. But now, with a recently developed innovative approach to the design of transmission and receiver antennae (coils), ubiquitous wireless power is ready to be incorporated into our daily lives throughout furniture, walls, and floors to efficiently and economically power all the gadgets we need for our electronic lives.

11 Myths About Magnetic-Resonance Wireless Charging

Tue, 30 May 2017 15:14:15 GMT

Written By Sanjay Gupta, VP Product Management, WiTricity

While the possibilities of magnetic-resonance-based wireless charging are very exciting, the technology is frequently misunderstood by those not involved in the industry.

Consider the devices we use every day: From smartphones and smartwatches and potentially electric vehicles, electronics are becoming as mobile as people themselves. We rely and expect our devices to be charged at all times, ready-to-use when needed. But as it currently stands, we still must plug in our phones, our electric cars, and our smartwatches, tethering us to cords and cables, triggering range anxiety and obsessing about the remaining juice on our devices.

氮化镓技术在四方面拯救地球

Tue, 11 Apr 2017 21:55:00 GMT

Gallium nitride (GaN) is a better semiconductor than silicon. There are many crystals that are better than silicon, but the problem has always been that they are far too expensive to be used in every application where silicon is used. But, GaN can be grown as an inexpensive thin layer on top of a standard silicon wafer enabling devices that are faster, smaller, more efficient, and less costly than their aging silicon counterparts.

How we devised a wirelessly powered television set

Fri, 10 Mar 2017 01:40:00 GMT

Televisions can get their content wirelessly, but there is one set of wires they still need: those in their power cord. The consumer electronics industry has floated ideas for freeing TVs from their power cords, but this goal remains elusive. There are several reasons, such as the difficultly of meeting high-power requirements for large-screen TVs and the need for identifying an economical technology. Nevertheless, eGaN FETs could play a role in making TVs truly cordless devices.

Mid-Year Checkup on My 2016 GaN Technology Predictions

Mon, 12 Dec 2016 19:47:00 GMT

Prognosticators do not often risk their reputations by giving their predictions a “checkup” midway through the period of their predictions. But, I am going to give it a shot and here we go…

My Predictions for 2017

Fri, 11 Nov 2016 09:17:00 GMT

In January of 2016 I made several predictions for the then-nascent year. Predictions were made for new markets such as wireless charging, augmented reality, autonomous vehicles, and advances in medical diagnostics and internet access. Progress in these markets was made on all fronts, sometimes faster and sometimes slower than anticipated. So here we are about to start a new year and, perhaps foolishly I am ready once again to predict the future.

Forget Everything You Thought You Knew About Semiconductors

Thu, 13 Oct 2016 21:51:00 GMT

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.

Emerging Applications in Medical Care Using GaN Technology

Tue, 28 Jun 2016 16:03:00 GMT

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.

GaN technology is getting exciting…end applications are emerging!

Tue, 07 Jun 2016 15:11:00 GMT

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:

Revisiting What It Takes for a New Semiconductor Technology to be Disruptive

Thu, 02 Jun 2016 17:34:00 GMT

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.
