Power will meet future needs
In the power electronics industry, embedded AC / DC power supply market is usually the most stable markets. However, there are a lot of applications, technology, business and management trends are large and stable on the combined effect of markets, as well as it brings opportunities and threats. One of the most popular trend is the growing power wattage, and pay more attention to power efficiency.
According to Darnell Group, the latest release of AC / DC power supply, the worldwide embedded AC / DC power supply market from 2006 to 118 million U.S. dollars to 14.8 billion in 2011. Annual growth rate of 5.8%. However, 500W more embedded AC / DC power supply growth rate is twice the overall market, although the fastest decline in its price. The trend to higher wattage applications by the rapid growth driven, including blade servers, Power over Ethernet (PoE), and data storage.
IBM is a leader in the blade server market, it is trying to consolidate its leading position in creating Blade.Org. Blade.Org by more than 40 technology leaders formed a coalition, including IBM, Intel, Nortel, Force10Networks so, the Alliance will develop and promote the next generation of blade technology. Blade server is for the AC / DC power supply to create opportunities, is expected to account for their server power supplies from the market in 2006 to 14% to 25% in 2011.
Blade server power supply problems of concern, because they require high-power power supply. A typical blade server appliance built on a chassis with 10 to 14 blade servers. Chassis usually have up to four hot-swappable and 2kW n + n redundant power supply. Therefore, full-power blade server rack easily exceed 20kW.
Blade servers to keep up with the growth of the power supply to power the power density must be increased. Practical Power Electronics Conference in 2006, the company from Delta Electronics and AstecPower speakers pointed out that the density required for improvement is coming. Both companies believe that 20W per cubic inch power supply high-end servers today, the benchmark, but by 2010, due to components, the power structure and improved thermal management, power density can be increased to every cubic inch 40W.
To push high-end server is not the only high wattage applications. Growing voice over internet protocol and more Wi-Fi access points are deployed to promote the growth of demand for PoE. PoE (standard IEEE802.3af) provides up to 15.4W per port power supply, power supply equipment is 12.95W transformed into usable power. 48-port switches are now very common device that when combined with other data routing functions, the required power of more than 1kW. In view of PoE power level has been pushed, an IEEE working group is trying to raise the level of PoE power density. IEEE802.3at also known as PoE-Plus, can the goal is to develop a PoE power per port to at least 30W of the standard. Thus, the relevant level of PoE power supply will be at least double.
The movements of a higher power levels across a variety of applications, accompanied by a distributed power architecture, especially the intermediate bus architecture (IBA), which adds rack-mount AC / DC front-end requirements. Corresponds to this demand, recently appeared on the market many new front-end power.
C & D Technologies, Inc. D1U-W-1200-12-HC 1U form factor can provide up to 1200W power, it is the company's front-end 1U power supply in a series, the series provides up to 1600W power. 1200W version for blade servers, workstations, storage systems and other 12V distributed power architecture with the application. In addition, the typical power efficiency of 91%.
Roal Electronics also increasingly interested in the data communications market with high-power front-end power.
Roal just launched the NC RHPS224 front-end power, it can provide 1200W 12V power output, and in the 48V output to provide 1500W. The device with an active power factor correction, digital multi-phase control technology. In addition, with the I2C bus or CAN-Bus provides the output voltage, current monitoring, and digital output voltage adjustment. AstecPower and Power-One has recently launched a numerically controlled AC / DC front end power supply.
In addition to the increasing use of high-power front-end power, these power supplies also shows to promote the AC / DC power market development in a number of other trends: 1) more attention to power efficiency; 2) to digital power supply.
As the inexorable rise in energy prices and the growing concern of greenhouse gas emissions, is expected to AC / DC power supply efficiency will typically improve in the coming years. From a management standpoint, EnergyStar, the California Energy Commission and other agencies around the world have increased the efficiency of external power requirements. Regulators with an external AC / DC power supply for a breakthrough, because it is basically a stand alone product. Now attention is devoted to these institutions are embedded in the AC / DC power supply.
EnergyStar is expected to be launched in January 2007 a new EnergyStar standards for computer label. The specification for servers, desktop PC, workstation, desktop, server and other similar applications. EnergyStar expected levels for a variety of desktop settings above 80% load efficiency and system settings for other similar specifications. Other regulatory agencies will follow suit.
Even without the management, efficiency is also becoming an increasingly important factor. As global energy prices, the cost of many data centers are facing double-digit growth, the system had to offer OEM business more energy-efficient servers, storage devices and data communications systems. For example, the North American data center electricity bills are soaring. High-end servers for the $ 8,760 annual average tariff, while the average data center electricity in 2005 increased by 20% or more. In addition, the power efficiency may help to slow migration to the way the demand for liquid cooling.
In 2004 and 2005, "digital power," a power electronics industry, a popular term. While most digital power concentrated in the DC / DC converters and regulators on the market, but also to see more new AC / DC front-end digital products. However, most OEM interested in not exactly the same digital control digital control of their acceptance. As the efficiency becomes increasingly important factor, the most valuable approach is based on load curve to achieve maximum power efficiency. This goal will continue to drive innovation, and today the number of AC / DC power supplies are more concerned about the number of settings in the output voltage, output order, and various monitoring functions, and similar features. That is, the mainstream embedded AC / DC power supply digital conversion is still in its infancy. AC / DC power supply market, many people want to NC to a higher power transfer efficiency and will help stabilize the market price. However, the current business trends are showing the opposite signs.
In the high-volume, low profit AC / DC power supply manufacturers and small volume applications in the gap between manufacturers will continue to expand. Delta Electronics is embedded in AC / DC power supply market share leader, but also in the high-volume, low-profit market to be successful, it confirmed the trend. 2005, Delta's overall revenues increased by 43%, contain embedded AC / DC power sector to keep pace with the growth rate of about 39%. In only 6% of total sales of a growth industry, these figures of particular concern.
Delta Company is one of the biggest advantages of low pricing, pricing negotiations, often used of materials (BOM) increase method. Some OEM manufacturer of commercial power on demand express their BOM cost, and then only slightly higher than a BOM OEM pricing. This method makes the price lower, more importantly, BOM-Plus pricing to increase power supply manufacturers have little room for profit.
Order in an increasingly fierce market competition, the five largest firms in the industry among the most recent of the three acquisitions between some. Market has recently entered a period of mergers, especially the major manufacturers. LambdaPower in the global market share in the fourth, which recently acquired by TDK, the establishment of a TDK-Lambda. Ranked fifth in the global market Artesyn is in the process of being acquired by Emerson Electronics, the latter is the world's third-largest power supply manufacturers AstecPower the parent company. The results of this merger is likely to exceed the Lite-ON Technology Corporation, which accounted for AC / DC power supply market, runner-up position.
AC / DC power supply market, including major manufacturers of joint trends in mergers, price declines and a shift towards higher functionality and higher power efficiency, they will in the next few years, stable market for the future to bring vitality.
