Global chip market growth speed digital power

With notebook computers, servers and digital television (DTV) applications such as growing use of digital control of power semiconductors, the market will certainly be in the next three years, from the newborn stage, started to grow rapidly, to 2011 revenue will reach 904 million dollars.

DPM DCP dominated sales growth

Power Manager (DPM) and digital control of power (DCP) belong to the scope of digital power. iSuppli Corporation of the DPM is defined as “the use of digital information to manage the power system and the overall function of the power of the device within the system.” With DPM, digital signals can be used for communication between the power to monitor and manage power-up, timing control, load sharing and balancing, fault status, hot swap, maintenance problems and other features. DCP control power of digital technology is used within the power switch, which means the earliest possible implementation of the analog – digital converter, in order to supply all of the feedback and control functions are processed in the digital domain.

DPM currently dominates the digital power market in 2007, accounting for about 77.8% of sales of digital power. This is because the DPM semiconductor present for most DC / DC (DC / DC) applications is an effective intermediate solution. DPM vendors are working to define the bus and its product development more friendly design interface, which allows DPM to control digital power market.

iSuppli predicts that by 2011, global sales of DPM and the DCP will rise to 904 million U.S. dollars, almost 153 million U.S. dollars sales in 2007 to 6 times. DPM will remain in the digital power semiconductor sales accounted for the largest share of annual sales will reach 613 million U.S. dollars in 2011, while the projected 2008 annual sales is 174 million U.S. dollars, 2008 -2011-year compound annual growth rate is 52.2%. However, DCP will be faster sales growth in 2011 annual sales from 60 million U.S. dollars in 2008 rose to 291 million U.S. dollars, a 69.3% compound annual growth rate.

iSuppli Corporation that, DPM the next 3 years will be low-end notebook computers and other devices to achieve even greater success. Meanwhile, DCP will account for more high-end servers and other equipment market.

Rapid growth in the notebook field DPM

From 2008 to 2011, the fastest growing digital control of power semiconductor applications will be a laptop in the DC / DC converter. 2011, the field of global DPM / DCP revenue from the 12.1 million U.S. dollars in 2008 rose to 149.8 million U.S. dollars, up 131.3% compound annual growth rate. DPM will be the largest component of operating income, operating income in 2008 accounted for 73.7%, 66.3% by 2011.

Even in 2011, the market will still be room for further growth, will be only 10.4% of notebook computers in the DC / DC conversion using digital power semiconductors.

The demand for improved efficiency, digital control power semiconductor applications in the field of notebook computers has been rapidly expanding. With the new generation of more powerful microprocessors are used, the importance of battery run time increased, efficiency is more critical than ever. DPM in the notebook area is another reason for the rapid development of laptop sales is more popular than desktop PCs.

2011 high-end gaming PCs in the field of DCP / DPM revenue from the 1.2 million U.S. dollars in 2008 rose to 11.3 million U.S. dollars, up 110.1 percent compound annual growth rate also.

DCP will dominate the server space

Growth rate immediately after the notebook computer digital control power semiconductor market will be high-end server, 2011, the area DCP / DPM revenue from the 2.9 million U.S. dollars in 2008 rose to 28.4 million U.S. dollars, compound annual growth rate of 114.3 %.

Over the same period, digital control of power semiconductors in the mid-range server in the field of sales will only be able to achieve a compound annual growth rate of 43.6%, but 2011 will grow to 125 million U.S. dollars, will be becoming the second largest digital power applications, DCP will dominate this area.

In the management of data centers and server center power and cooling encountered major challenges, which is to promote the server using the principal factor in DCP. These facilities consume much energy, and heat generated may sometimes lead to equipment failure, malfunction, some of which come from energy conversion. DPM and the DCP can be used to improve the efficiency of energy conversion. In idle mode, the analog and digital solutions, power consumption difference is particularly marked.

DPM prospects for digital TV

Another fast-growing application areas will be digital TV. 2011, digital TV uses the DCP / DPM solutions revenue from the 11.4 million U.S. dollars in 2008 rose to 39.6 million U.S. dollars, compound annual growth rate of 104.4%.

With the TV screen become larger and larger, the energy required to drive the display was significantly increased, so the power efficiency has become more important. In anticipation of the price cuts DPM will be greater than DCP, so DPM penetration in the digital TV market faster than DCP. iSuppli predicts that by 2011 digital power in the DTV market share will reach 3.4%.

DCP and the DPM is now expected to be large volume, the device can create revenue, so that application of these devices products save a lot of power, and will provide related products providers drive significant revenue.

Unlimited potential of fuel cells

Although fuel cells appear in the eyes of the term time is not long, but its history can be traced back 100 years has had. In 1889, Ludwig Mond and Charles Langer two chemists want to use air and industrial gas manufacturing a functional device that can provide electricity, "fuel cells" is also with their invention is born. The rise of modern fuel cell technology in the 20th century, 60 years, the space shuttle in order to find high-performance power unit, with GE, NASA to develop the first fuel cell in the modern sense - the proton exchange membrane fuel cell, which is the fuel cell the beginning of commercialization. Since then, after 40 years of development, more and more of the fuel cell family, a flourishing population, but also throughout the entire application domain.

Principles and characteristics of fuel cells

Fuel cells are combined into the water by the reaction of hydrogen and oxygen to generate electricity, and thus does not produce nitrogen oxides (NOX) and hydrocarbons (HC) and so easy to pollute the air the material. It consists of three components: cathode, anode and electrolyte, according to the different electrolytes can be divided into molten carbonate fuel cell (M CFC), solid oxide fuel cell (SOFC), alkaline fuel cell (AFC) , phosphoric acid fuel cell (PAFC) and proton exchange membrane fuel cell (PEMFC) five types.

Fuel cell has several unique properties:

A fuel cell must have energy at work

2 fuel cells can generate electricity only, and Supply the fuel, as long as the supply of fuel can generate electricity, the discharge is carried out continuously.

3 fuel-cell mass and body size is not large, but the need for a fuel storage or fuel switching devices and ancillary equipment to get hydrogen, and these fuel storage device or fuel switching devices and ancillary equipment far exceeds the quality and volume of fuel the battery itself.

Common fuel cell

Proton exchange membrane fuel cell (PEMFC) in proton exchange membrane fuel cell, the electrolyte is a thin polymer membrane, such as poly [perfluoro methyl] acid (poly [perfluorosulphonic] acid), and protons can penetrate, but not conductive NafionTM and the electrode base from carbon composition. Hydrogen into the fuel cell to reach the anode, cracked into hydrogen ions (protons) and electrons. Penetration of hydrogen ions through the electrolyte to the cathode, while the flow of electrons through the external network to provide electricity. Meanwhile, the supply of oxygen form the air to the cathode, combine with electrons and hydrogen ions to form water.

Alkaline fuel cell (AFC)

Alkaline electrolyte fuel cell using a stable aqueous solution or potassium hydroxide matrix, and the electrochemical reaction with the hydroxyl (OH) move from the cathode to the anode to react with hydrogen to form water and electronics are slightly different. These electrons first to provide energy for the external circuit, and then come back to the cathode reaction with oxygen and water, more hydroxyl ions.

Phosphoric acid fuel cell (PAFC)

The batteries use liquid phosphoric acid as the electrolyte, the working temperature than the proton exchange membrane fuel cells and alkaline fuel cell operating temperature is slightly higher, at about 150 ~ 200 â„? but the platinum electrode catalyst needed to accelerate the reaction. The anode and cathode reactions and proton exchange membrane fuel cell the same, but because of its high operating temperature, so its faster than the reaction on the cathode of proton exchange membrane fuel cell cathode speed.

Molten carbonate fuel cell (MCFC)

Molten carbonate fuel cell using molten lithium potassium sodium carbonate or lithium carbonate as the electrolyte. When the temperature is heated to 650 â„? this salt will melt, producing carbonate ions from cathode to anode, and hydrogen combine to form water, carbon dioxide and electrons. Electronic circuit and then returned to the cathode through an external, in the process to generate electricity.

Solid oxide fuel cell (SOFC)

Solid oxide fuel cell operating temperature than the molten carbonate fuel cell temperature even higher, such as by using yttria stabilized zirconia and other solid ceramic electrolyte, instead of using the liquid electrolyte. Its operating temperature at between 800 ~ 1000 â„?

In this fuel cell, when the oxygen ion moves from the cathode to the anode, the oxidation of fuel gas (mainly a mixture of hydrogen and carbon monoxide) to produce energy. Anode-generated electrons move back to the external circuit on the cathode, reducing the oxygen, thus completing the cycle.

Development Status

Because the energy and environmental considerations, countries and regions are stepping up development of its own fuel cell program. But because of different national conditions, the focus is also different.

Fuel cell was designated as the United States, 27 one of the technologies to be developed, while the proton exchange membrane fuel cells is one of the key. To this end, the U.S. government set up the hydrogen, fuel cells and infrastructure technologies office. Meanwhile, the U.S. investment fund companies and a variety of fuel cell projects are also given a lot of input.

Japan's enthusiasm for fuel cells as much as the United States, the government investment in this technology is also increased every year. Japan has developed a fuel cell for several public power sector, including phosphoric acid fuel cell (PAFC) has reached the "power" stage. There are also a large number of small fuel cell power generation device is used in hospitals, hotels, guest houses in the. EU in the past 10 years, through the Framework Programme of the auto industry and fuel cell technology development to provide a great deal of research and development support. EU is also increasingly interested in fuel cell vehicle demonstration projects, but unlike the United States and Japan attach great importance to passenger cars as a model, and to focus on the large number of transportation applications.

Vehicle fuel cell research in China has made a good start. "Fifth" period, electric vehicles in the country listed in paragraph 863, was identified as the national one of 12 major science and technology. China is also the Global Environment Facility / United Nations Development Programme to establish fuel cell cooperation projects, together provide about $ 19,800 in financial support. Through science and technology research, has developed dozens of 100kW and above the fuel cell power system for vehicle play a positive role in promoting improved.

The world's first SOFC / gas turbine hybrid system in the University of California, Irvine National Fuel Cell Research Center of running. The total system power is 220kW, 200kW of which came from SOFC.
The System, running not only to send the fuel into a shot in the arm to open, but also to the growing problems facing the world energy provides a new solution ideas.

New nickel mine development project

Nickel price slump that delayed the development of new projects, but the market outlook remains positive

London, Oct. 29, according to the message, the industry said on Wednesday, nickel prices have fallen sharply so that the new nickel mine development project delayed due to sharp drop in nickel prices, these items may not be profitable, so that the future nickel market will result in tight supply, and promote higher nickel prices.

Listed in London, European Nickel Industry Corporation (European Nickel) manager Simon Purkiss said Wednesday, "the current financial crisis could bring nickel prices increase again."

LME three-month nickel in May 2007 had hit a record high of 51,800 dollars, which caused many in the global nickel exploration and production projects of new investment boom.

However, nickel prices hit a record high, the stainless steel producers began to use alternatives, nickel demand fell, followed by economic crisis, all commodities are faced with selling and promoting nickel prices fell on Wednesday, 12,300 U.S. dollars per ton.

Albidon said Dale Rogers, CEO, "Nickel prices fell to $ 4.5 per pound (9,921 U.S. dollars / ton), or 5 U.S. dollars (11,023 U.S. dollars / ton) around, about 40% nickel producers are losing money."

Decline in nickel prices, producers fell, financing difficulties forced many producers to stop the pace of expansion of existing projects and delay the development of new mines, so that when the recovery of global nickel demand, the nickel market will once again supply tight.

Dale Rogers said, "estimated that nickel prices will rebound at some point."

Albidon's Munali company is located in southern Zambia nickel mine has begun production, estimated in the first quarter of 2009 reached full design capacity.

Standard Bank said in a report, it is estimated this year's global nickel production (including China's nickel pig iron) material reduction of 150,000 tons of global nickel production expected 140 million tonnes.

Mirabela Nickel CEO Nick Poll said, "there will be nickel project will be discontinued or reduced, as they in the current market conditions, is unprofitable."

"So, the long term, nickel market prospects."

Simon Purkiss said the long term, the nickel market outlook bright, due to come from emerging economies such as Brazil, Russia, India and China's demand will increase, while production capacity and other material made to defer the next few years the market supply tight.

Lithium Battery Energy saving Upsurge

With the constant fluctuations in international oil prices, energy saving environmentally friendly lithium battery in the limelight once again a hot topic. From 6 months, the number of international auto companies and electronics companies are using large-scale lithium battery joint investment. Including Toyota and Matsushita, Nissan and NEC, Volkswagen and Sanyo, Bosch and Samsung, they believe that lithium batteries in the next few years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. Li-ion battery in the heat of global investment background, China's automotive enterprises in this research work is in what kind of? Experts on the lithium battery is holding what kind of attitude? Recently, the reporter interviewed specifically on this issue who has studied the domestic lithium battery, several experts.

Beijing Institute of Electric Vehicle Engineering Center Deputy Director Lin Cheng

Study of lithium iron phosphate has been a breakthrough

Lin Cheng told reporters, demanding automotive lithium batteries. It requires that the vehicle used in a variety of conditions, must protect the security, can not occur fire, explosions and other accidents. The first was for battery electric vehicles, in this country has made great breakthroughs have begun to take industrial scale. But 5,6 years ago, with the battery powered vehicles are often some accidents, such cells will gradually be diluted. Now, the domestic lithium battery research progress quickly, especially in the battery safety issues, has made great progress.

Lin Cheng told reporters, lithium batteries include lithium manganese oxide and lithium iron phosphate batteries. At present, the development of the domestic lithium manganese oxide has begun to take shape. Lithium iron phosphate as safer, longer life, will become an important direction for future development of lithium batteries, but also abroad, the focus of research and development of the automobile. At present, lithium iron phosphate studies of good progress, especially in some of the patent on a breakthrough, this time for the Beijing Olympic Games is a passenger car with a self-developed lithium iron phosphate lithium battery.

"Of course with the study abroad compared to lithium batteries, the domestic lithium battery research still lags far behind, but the domestic lithium battery emphasis on increasing, the future will be the R & D focus." Lin Cheng told reporters.

Henan Huanyu Group lithium battery industry technology Deng Lun-ho, deputy chief engineer

Large-scale lithium batteries for electric cars need some time

Henan Huanyu Group is a component from the battery to the battery cell manufacturing plastics and related hardware, equipment manufacturing, electronics manufacturing, a complete industrial chain of the Enterprise Group, has undertaken the project of Science and Technology Li-ion battery research and development.

"At present the domestic lithium battery research and abroad, the gap is mainly reflected in the battery control system and power management systems." Deng Lun-ho told reporters that now the domestic lithium battery research for development in their respective state. Currently, some companies have been able to provide the corresponding lithium battery electric vehicle accessory products, supporting the general lithium batteries can run 200 to 500 km.

Deng Lun-ho told reporters that now the price is too high the domestic lithium battery, power management system problem has not yet been well resolved. Charging electric vehicles also face the problem. Currently, the general line at home can not charge lithium batteries for electric vehicles must be equipped with a small dedicated charger, and charging time is very long and very troublesome. Abroad, in order to solve this problem, generally regarded charging stations and gas stations together. China is now charging stations have not established a large scale.

Deng Lun-ho believes that the current consumer acceptance of electric vehicles equipped with lithium batteries it still more difficult: "the price of an ordinary electric car is about twice the same configuration or even higher gasoline locomotives, domestic consumers have not enough economic prepared to accept the power and electric vehicles. "

China Electric Power Research Institute engineer Chuang Feng

Optimistic about the prospects for the development of lithium iron phosphate

Chong Tong, told this reporter, the electric vehicle battery research and development work has gone from lead-acid batteries, nickel-metal hydride batteries to the development of lithium batteries, each battery advantages and disadvantages.

The earliest to appear in lead-acid batteries, used in the longest time, belonging to the battery series. The best safety performance lead-acid batteries, rare explosion, fire and other phenomena, energy storage effect is not ideal. Later, people developed a nickel-metal hydride batteries, store energy and power than the effect of the ideal lead-acid batteries, but due to nickel-metal hydride battery in the charging of hydrogen generated in the process prone to explosion, so the nickel-metal hydride batteries in a business may or may not state.

To the year 2000, people developed a lithium battery. Lithium batteries are lead-acid storage battery of power 2 to 3 times, but because it contains lithium-ion active in the metal layer surface, prone to spontaneous combustion in the air, explosions, etc., higher risk. So now the major countries is to control the development of lithium batteries is safety and stability.

"Charging a lithium battery would be able to cycle around 1000, in which the stored energy of lithium iron phosphate is better than lithium cobalt oxide and lithium manganese oxide effects worse, but it's the best safety performance, than lead-acid battery energy storage much higher, so now the most promising lithium iron phosphate. "Chuang Tong said.

Society of Automotive Engineers of China, director Chen Quanshi branch of electric car

Three problems of domestic lithium battery research

Quan-Shi Chen said in an interview: "Now the state attaches great importance to the study of lithium batteries, '863 'project, the state invested a total of 66 million yuan, all development work for the lithium battery. We and Japan, the United States such as walking in the lithium battery research and development in the forefront of the developed countries, China's lithium battery manufacturing precision, equipment, standards, etc. there is a certain gap between R & D details. "

Quan-Shi Chen told reporters that at present there are three issues of domestic lithium battery research. The first is the consistency of manufacturing. Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able.

Followed by the intellectual property rights. Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.

The third issue is the selection of raw materials. Now the production of raw materials used in lithium batteries can not all imported, mainly from China, but domestic raw materials, through international certification, to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems.
