Fairchild’s products are sold through high-performance battery management
China Electricity Council (China Electricity Council, CEC) said the Secretary-General Wang dry, it is expected that China’s electricity 6y270 battery, c1295 battery, dell inspiron 500m battery, dell inspiron 510m battery market in 2007 will show a balance between supply and demand. At present, China is the best turn our attention to the management of energy resources research.
All along, the low-energy efficiency is China’s industrial and commercial development in the expansion of one of the major challenges. China’s overall energy efficiency of only 33% lower than other developed countries by 10 percentage points, while the energy consumption per unit output value is twice that of other developed countries.
In order to bridge this gap, China has to improve energy efficiency and save resources as a national priority, but also one of the basic national policy of the Government. Numerous regional and national energy-saving initiatives have been established, aimed at reducing energy consumption, improve energy efficiency. For example, Shanghai has been the introduction of energy-saving lamps 420,000; bustling Huaihai Road, Shanghai, 6,500 incandescent lamps are energy-saving cold cathode lamps (cold cathode lamp) to replace, which will reduce energy consumption up to 90%; and Beijing Olympic Committee Hotel also advocated the installation of “winter tune cool warm summer tune” the thermostat and is expected to reduce power consumption 10-15%.a
In addition, China for the domestic refrigeration and air conditioning regulate the energy efficiency labels (Energy Labeling Regulations) in March 2005 entered into force. The scheme aims to enhance the terminal equipment of the power efficiency and reduce greenhouse gas emissions (emission of greenhouse gases). According to these norms, and in September 2005 did not target the products will be banned from sale, China National Institute of Standardization (China National Institute of Standardization) has forecast about 15% of the high power consumption refrigerators will be eliminated.
Fairchild, president and chief executive Mark Thompson said: “Fairchild power experts as The Power Franchise, is the market leader in power semiconductor suppliers, we will be able to help China meet its energy needs. Fairchild focus on the development of systems to optimize power products, and continue to turn to higher-value analog devices and power discrete solutions, these are issues on China’s impact on power consumption. In addition, Fairchild, through the design and development of new semiconductor products, in support of China’s energy efficiency labeling norms play a key role. these new products by means of an effective dell inspiron 600m battery, dell latitude d500 battery, dell latitude d505 battery management, can minimize the power grid and demand for power savings. ”
Power demand to minimize
For domestic white goods such as refrigerators, washing machines and air-conditioner market, Fairchild developed the Intelligent Power Module (SPM) devices, for these energy-constrained applications inverter to provide an effective motor control. SPM will be high-voltage IC (HVIC), low-voltage IC (LVIC), IGBT and fast recovery diode are integrated in a heat efficiency of the package (thermally efficient packaging), you can improve energy efficiency and system reliability. SPM can significantly save power, Thompson said, for example: “In a single air-conditioner, a constant speed of the inverter can provide energy savings of up to 40%. China Daily in 2004 showed that air-conditioning in China in 2003 consumed the total energy of 700 billion kilowatt-hours, which can be equivalent to 28 billion kilowatts hours of energy. ”
In switching power supply (switch mode power supply), it is a color TV, set-top boxes and laptop adapter, as well as handheld devices (such as PDA and mobile phone) the battery charger in an integral part of, the manufacturer must be able to reduce the standby power, and in accordance with government agencies regulate the mandatory power savings.
Thompson continued: “Fairchild Green FPSTM device using the switching power supply design, power savings can be significant to meet the efficiency requirements and regulations in line with the norm. For example, each year a general TV standby power consumption is 55.2 kW, and the use of Green FPS TV’s standby power consumption each year is only 7.3kW. Therefore, the use of FPS, customers can save each year 47.9kW of energy. engaged in environmental education non-profit non-governmental organizations of the Global Village of Beijing has been estimated that for every 1 kilowatt-hour savings, we can 25-watt light bulb for 40 hours electricity supply; refrigerator can run all day; ordinary fans run 14 hours or 10 hours to run television. ”
The use of a wide range of Power Factor Correction (Power Factor Correction, PFC) product to ensure maximum efficiency of power distribution (power distribution), is the Fairchild Another major area of expertise. PFC helps to regulate current to comply with the requirements of the input voltage and power factor from 0.65 (typical SMPS) to greater than 0.95. Fairchild’s PFC solutions include the ability to reduce costs and reduce the power loss (power loss) of the PFC / PWM controller. These PFC / PWM controller integrated PFC and PWM in one IC, thereby enhancing the efficiency of the PFC can be used to increase bandwidth, reduce the ripple voltage (ripple voltage) and output capacitor size, and lower electromagnetic interference (EMI) and system noise.
Save power and highly efficient battery management
Fairchild μSerDesTM the device is ultra-compact package of the string / deserializer for the ultra-portable and consumer electronics applications in high-speed, low power and low noise performance. Of these strings / deserializer through EMI with very low power and two-way interface provides a pathway dell latitude d510 battery, dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery, this interface is very flexible and easy to use, and support for pixel (such as RGB, YUV), micro-controllers and other structure, and the reduction of system components (such as cables, filters and shielding cases) the total number. SerDes with traditional solutions, μSerDes only the size of the former 1 / 7; the work of power is only 1 / 10; standby power of only 1 / 4000, and substantially reduce EMI.
Fairchild’s advanced 50mA to 400mA load management products IntelliMAXTM series integrates a variety of important functions of protection and control of power management switch. This set the protection, control and fault monitoring features in a small SOT-23 package in a unique design, can solve many critical issues, such as power management to streamline design, combined with advanced control and protection functions to support the latest generation of technology and structure, as well as 1.8V to 5.5V, the largest of a wide range 6V ABS voltage. As the market tends to gather a wide range of features into consumer electronics products (such as with cameras, MP3 players and PDA’s smart phones), the industry’s Fairchild IntelliMAX load management devices and control functions important to the protection of the demand for more and more strong.
Thompson concluded: “the next few years, China’s demand for high-energy efficiency is still a very important thing, Fairchild plans to further consolidate its power in the fast-growing semiconductor market leadership. We are focusing on strategies to increase R & D investment to develop more integrated products based on power and resources through the addition of Global Power (Global Power ResourceTM) Design Center to enhance customer support. In addition, we will increase the local field application engineers to enable them to cooperate directly with customers, and to expand Design Center in China. Fairchild’s objective is to ensure that the first company in China, the status of power semiconductor suppliers. ”
China’s third-generation hydrogen fuel cell vehicle the “heart” of a top speed of 120 km / h
Tongji University runway spacious, three new Santana repeated the forward acceleration, turning the basic movements, posture light. A traditional sense for any new car, so the test is not worth mentioning. However, all the presence of examiners – 863 major projects of national members of the Group, everyone knows the weight of this report card: with the international advanced level compared to China’s own R & D of fuel cell vehicles by no means inferior to its hydrogen-powered “heart” even more than the international giants have far more robust.
Just through the acceptance of China’s third-generation fuel-cell cars – “beyond the 3rd.” Report card on each of the indicators are exciting: a top speed reached 120 km / h, just a short span of 16 seconds will be able to accelerate to 100 km / h, with a total mileage added up to driving 230 kilometers – all of which are completely different from the internal combustion engine depends on a new engine. It is not only all the “Beyond the family,” the power source, but also has driven the development of the Tsinghua University’s three fuel cell city bus run on a total of 10,000 kilometers.
Few people know that inhaled hydrogen, pure water out of the fuel cell engine, hundreds of people from a small company – Shanghai Science and Technology. Today, General Manager and Technical Director Dr. Hu Liqing, Shanghai will be granted to the ninth “technology elite” of winning.
As a private enterprise engaged in fuel cell 7 years, however gd761 battery, kd476 battery, td347 battery, dell inspiron 1501 battery, less than a total of 100 million yuan in funding. Today, the technology it nearly enough to shake the market value of billions of dollars in Canada Ballard Fuel Cell World status of eldest child, the applicant, the United States as many as 217 patents. Last year, in Shanghai at the global Clean Car “Challenge Bibendum”, the five Chinese-made fuel cell vehicle equipped with the same color to the hydrogen the “heart.”
Huri-ching said that with the giant strength, divine power does not have a strong leverage, leveraging before the divine power to find the right fulcrum. In fact, in Hu-ching said the fulcrum, not a secret. Fuel cell system in the original, one of the ills of the world knows, that is, hydrogen and oxygen to enhance the efficiency and speed of response, it is necessary to air pressure. And this is to run the entire engine system of high-power, the system is complicated and costly, unsafe, such as a series of “after-effects.” For these, the whole world to be helpless again. Qing Hu Village feel that pressure should not be the only way that only a surprise move, it may .
In 1998, Ballard resigned huri-ching, senior project manager jobs, home business. At a distance of more than thirty kilometers Shanghai the industrial zone, he began to explore a route different from the authority of the technology. That is, under normal pressure in the fuel cell system, so that did not “close” the hydrogen and oxygen become “excited” to maximize the efficiency and rate of reaction. To this end, he tested a full 4 years to speed up the reaction of the catalyst formulations do not know how many tried. Finally, in 863 projects towards the end of the first round, successful.
“Beyond the” family of one, two, three generations of recording across three subsequent . Just two years, this hydrogen the “heart” of the weight loss of half the weight of the battery unit has increased the output power of 1 times the fuel efficiency from 39% to 45%, surpassing the company’s Ballard the highest level. The corresponding, “beyond the” family maximum speed, the amount of hydrogen consumption of 100 kilometers, “power”, “endurance” and optimize the performance year after year. As the choice of the atmospheric air, the innovative line of low pressure hydrogen, the engine cost only General Motors, Mercedes-Benz, such as the company’s 1 / 8, for the industrialization of dell inspiron 6400 battery, dell inspiron e1505 battery, dell latitude 131l battery the upcoming removed the biggest obstacle.
