Alex Lidow是一个有使命感的人。他在美国加州成立的宜普电源转换公司（EPC）在全新应用中使用氮化镓（GaN）晶片而摒弃硅基技术。这些应用包括无线电源充电、4G LTE、扩增实景（AR）及全自动驾驶车辆等令人感到兴奋的应用领域。

可是，這種熱門新技術最後能否替代被普遍採用的矽基晶片及佔據其高達3000億美元的半導體市場份額嗎？

The demand for information in our society is growing at an unprecedented rate. With emerging technologies, such as cloud computing and the Internet of Things, this trend for more and faster access to information is showing no signs of slowing. What makes the transfer of information at high rates of speed possible are racks and racks of servers, mostly located in centralized data.

In this series we will look at the various ways the reliability of eGaN^® technology has been validated, and how we are developing models from our understanding of the physics of failures that can help predict failure rates under almost any operating condition. In this first installment and the next, we will look at the field experience from the past six years of GaN transistors use in a variety of applications from vehicle headlamps to medical systems to 4G/LTE telecom systems. Diving into the failure of each and every part leads to some valuable lessons learned.

Power transistors with faster switching speeds will enable power supplies with smaller form factors and higher energy transfer efficiencies. Indeed, the elimination of heat sinks will give designers the ability to visualize entirely new form factors for power bricks and modules, including those enabling wireless power transfers. Gallium-nitride (GaN) transistors fabricated on silicon substrates can boost efficiencies and help shrink the footprint of power supplies.

In this installment, we present a method to design a suitable EMI filter that can reduce unwanted frequencies to levels within radiated EMI specifications, and do this without negatively impacting the performance of the wireless power coil. In addition, the overall radiated EMI design aspects will also be covered.

Improving low-voltage DC/DC converter performance with GaN transistors:
The emergence of commercially available and cost-effective gallium nitride (GaN) power transistors begins a new age in power electronics. There are significant benefits in using enhancement-mode gallium nitride FET (eGaN FET) devices in power converters for existing data center and telecommunications architectures centering around an input voltage of 48 VDC with load voltages as low as 1 VDC. High-performance GaN power transistors can enable new approaches to power data center and telecommunications systems with higher efficiency and higher power density than possible with previous Si MOSFET based architectures.

Some of the best minds in our industry, like the group that was at a DesignCon 2016 book signing. Among them was Michael de Rooij, Efficient Power Conversion VP of Application Engineering who signed copies of his book Wireless Power Handbook, Second Edition. DesignCon attendees enjoyed browsing and buying books and having the authors autograph them as well. The authors also answered questions and discussed their areas of expertise with inquiring minds in attendance.

According to Powerpulse.net, “This selection is based on EPC's domination of the 50 most-read product news stories for 2015. EPC products account 8 of the top 50 product stories for 2015 (as measured by readership). This is the first time that a single company has accounted for such a large number of product news stories (that amounts to 2 per quarter), including 1 in the Top 10 and 5 in the Top 20.”

With the backdrop of slower global economic growth and expected higher interest rate in 2016, Alex Lidow, CEO of Efficient Power Conversion Corporation opines that companies looking for late-stage financing will see a greater emphasis on fundamentals such as revenue, margin and cash flow, and a lower emphasis on less-tangible metrics, such as the size of an audience without strong monetization.

With mega deals for mergers and acquisitions took place in the past year, would innovations be stalled? Alex Lidow, CEO of Efficient Power Conversion Corporation said if you look at semiconductor end sales in this century, we have only seen a 5% compounded annual growth rate. It’s clearly showing signs of an end market that is very large and very mature and in the same time, the cost for a new facility or new product has skyrocketed.

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.
