雜談GaN技術

隨著馬達技術的進步，功率密度增加；馬達被製成更小的形式，設計速度更高，精度更高，這需要更高的電氣頻率。

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!

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.

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.

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.
