在2014年，美國的數據中心用上了1000億千瓦小時（KWh）能量。雪上加霜的是，這個快速增長的所需能量，大部份是由基於超過一世紀前設立的基建、非常低效的供電網路支持。浪費了的能量有多嚴重？供電網路為一個數字晶片提供150 W功率，而實際上，它可能只需要100 W。 此外，由於在電源轉換過程中，每一瓦功耗會轉化為熱量，因此實際上所浪費的能量更大。而我們必需利用昂貴及耗電的空調機來為伺服器群散熱。空調機大約需要1 W來除去1 W的功耗，這相等於已經低的能源轉換效率將再降低一倍。

全新半導體材料的出現可提高能源轉換效率，其成本也可以更低。在伺服器群中的功率結構的最後階段解決低效率的問題，可以實現每年節省70億千瓦小時的能量。如果一併計算空調機的能源成本，總成本倍增並佔了美國的所有伺服器的總能耗的14%。所能夠節省的成本也是非常巨大的。以每一千瓦小時的平均成本0.12美元來計算，每年可以節省的總成本高達17億美元，這還沒有包括由於採用更少數量的功率轉換器及空調機而得以額外節省的系統成本。

DC-DC “brick” converters are familiar to many engineers, and have wide usage in telecommunications, networking, data centers, and many other applications. This is due in large part to adoption of a common footprint defined by the Distributed-power Open Standards Alliance (DOSA) and generally accepted input/output voltage ranges. These converters provide isolation and voltage step-down, and have become increasingly sophisticated, with features that enable advanced system optimization and control.

“The semiconductor industry will become one where there are a lot of large corporations and smaller companies will, in effect, be outsourced R&D, much like the pharmaceutical sector,” says Alex Lidow, CEO of Efficient Power Conversion. He says in this scenario Qorvo Corporation and Intersil Corp. could become attractive targets.

Lidow, however, believes consolidation may bring a dark ages to innovation in the semiconductor industry.

Semiconductor firms have announced $100.6 billion in mergers and acquisitions this year. Chip makers have long used acquisitions to obtain new technology. But many recent deals resemble consolidation waves in older industries, motivated mainly by trimming costs in areas like manufacturing, sales and engineering.

The combination of lower on-resistance, faster switching speeds, lower thermal impedance, and smaller physical size of eGaN FETs continues to raise the bar for power transistor performance. As GaN technology matures, not only does the performance of these transistors rapidly improve, but significant reductions in cost are also realized. Not only will GaN devices continue to enable new applications, they will replace silicon power transistors in cost-sensitive applications as well. As a matter of fact, the first signs of this happening are already here.

The company Alex founded in 2007, called Efficient Power Conversion, or EPC, is wholly dedicated to the task of putting GaN in the forefront for use in a variety of things. Wireless power transmission, Class D audio amplifiers, (using a small circuit board, this would produce less heat, and extend battery life on portable systems); and pulsed lasers, or LiDAR (Light Distancing and Ranging), designed to quickly create 3D images useful in mapping and meteorology.

Wireless charging may have a standards battle to contend with, but there’s also a major a measurement problem. The quest for convenient living and energy conservation poses a ‘Ying/Yang’ dilemma living in the age of electronics. This is certainly the case with wireless power transfer technology. This rapidly emerging technology has the promise of “cutting the cord” and displacing the need for AC/DC wall adapters and perhaps eventually wall sockets. The question now is; will wireless power increase our carbon footprint by being less efficient than the traditional plug-in AC/DC wall adapters?” Are some wireless systems more efficient than others? These are two fundamental questions that need to be examined in an energy conscious world governed by energy efficient standards.
