Emerging applications such as 48V-to-point-of-load (POL), wireless power and USB Type-C had a lot of interest. Google joined the Open Compute Project a few weeks ago and proposed a computer server-rack architecture based on a 48V power-distribution bus to improve overall system efficiency. While the 48V bus has been around for a long time, the push (and challenge) is for high-efficiency 48V-to-POL voltage regulators. EPC showcased TI’s 48V-to-1V EVM which uses the LMG5200 GaN module (driver and FETs), announced at APEC last year, and a new TI analog controller (TPS53632G).

您可能阅读过ECN杂志编辑（及新闻总监）所写的关于幕后故事的推文，以及一张照片可比千言万语表达得更好。可是，有的时候，听听工程師分享他們的感想及真知灼見可以是更有价值的体验。

我就是这么想，在加州Long Beach举行的APEC会议上，与多位工程师及与会者见面以找出本届APEC的内幕消息。我们比较了APEC与去年研讨会的盛况、目前业界的主要发展方向及各公司对APEC研讨会的评价。

从本年的APEC研讨会的各个讨论题目显然可以看到，氮化镓功率技术的相关知识备受关注的程度，是前所未有的。采用氮化镓技术的产品路演、全新产品及技术发布、全体会议对氮化镓技术的关注及其他讨论题目都让与会者感到氮化镓功率器件已经来临，而氮化镓技术正在进驻市场。而且讨论重点也稍微改变，从讨论氮化镓器件可以做什么，改为讨论需要其他什么资源及支持，才可以实现基于氮化镓功率晶体管的全新产品开发方案。

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，这种热门新技术最后能否替代被普遍采用的硅基晶片及占据其高达3000亿美元的半导体市场份额吗？

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.

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，美国的数据中心用上了1000亿千瓦小时（KWh）能量。雪上加霜的是，这个快速增长的所需能量，大部分是由基于超过一世纪前设立的基建、非常低效的供电网路支持。浪费了的能量有多严重？供电网路为一个数字晶片提供150 W功率，而实际上，它可能只需要100 W。 此外，由于在电源转换过程中，每一瓦功耗会转化为热量，因此实际上所浪费的能量更大。而我们必需利用昂贵及耗电的空调机来为伺服器群散热。空调机大约需要1 W来除去1 W的功耗，这相等于已经低的能源转换效率将再降低一倍。

全新半导体材料的出现可提高能源转换效率，其成本也可以更低。在伺服器群中的功率结构的最后阶段解决低效率的问题，可以实现每年节省70亿千瓦小时的能量。如果一并计算空调机的能源成本，总成本倍增并占了美国的所有伺服器的总能耗的14%。所能够节省的成本也是非常巨大的。以每一千瓦小时的平均成本0.12美元来计算，每年可以节省的总成本高达17亿美元，这还没有包括由于采用更少数量的功率转换器及空调机而得以额外节省的系统成本。
