Smart Grid brings many opportunities for micro-electronics




Smart grid construction will provide new opportunities for the semiconductor industry. Wang Zhihua, deputy director of Institute of Microelectronics, Tsinghua University introduced the world's total electricity consumed in the grid within about 40%. The building of smart grid is to improve the efficient and effective means of power transmission, while the power of intelligent integrated circuit made of a higher demand. Smart grid systems to be able to sense overload and can distribute electricity; smart grid digital technologies, including the use of intelligent power consumption meter testing, through the network of sensors and computer system control burst generators, according to consumer demand, production of electrical energy, thereby enhancing transmission efficiency; Another feature of smart grid is to allow distributed alternative energy into the grid, according to the U.S. Department of Energy predicts that by 2030, wind energy will provide 20% of U.S. electricity demand, which also integrated circuits and semiconductor power devices to provide a market opportunities. The formation of wind power is unstable alternating current rectifier device will need to convert it to DC, then convert the inverter AC power grid can be accepted after the delivery to the grid and going; while the formation of the solar cell power generation DC, also need The power inverter only after the conversion, and network. Both the rectifier or the power inverter, the core of all power semiconductor devices; and distributed energy in the input grid in the process of measurement will have to rely on integrated circuits.



The new energy vehicle electronic system is IC Innovations



Xiamen King Long United Automotive Industry Co., Ltd. Technology Center, said Chen Xiaobing, deputy director, is expected in 2010 China's auto electronics market size will reach 2,000 billion yuan. 2009 to 2010 compound annual growth rate of 26.1%. He also said that in the next few years, several areas of automotive electronics will drive the growth and technological innovation. To hybrid vehicles and pure electric vehicles as the representative of the new energy vehicles become the focus. Among them, multi-channel battery-management chip, multi-channel battery voltage balance control, high-voltage monitoring, high-current testing, large-scale power semiconductor devices, a number of high-performance MCU / DSP chip (SoC to meet the complex calculation of the battery management), and isolators are all part of the new energy vehicle electronic systems areas.



Wireless technology and applications will become very popular



According to market analysis and published by Ovum, the market is expected to show that the global wireless market is growing bright spot in the next four years, by 2012 the global mobile phone subscribers is expected to reach 4.99 billion, the wireless market revenue will grow to 1.019 trillion U.S. dollars. In our case, the 3G investments, according to the operator's network development plan published point of view, from 2009 to 2011, three years, 3G will pull 1 trillion yuan of domestic investment. Specific to TD-SCDMA field, the next three years, China Mobile will invest 150 billion yuan, goal is 50 million users. There can not be ignored around the "Wireless City" and other information-oriented construction projects brought about by investment-led. According to statistics, currently the world's "wireless city" has reached more than 1,000 the number of China's many "Wireless City" in 2010 into a large-scale acceleration phase. The market will drive the base station chips, cell phone chips and WLAN chip development.
