Environmental protection, economic benefits and practical application requirements are the three major factors that promote the development of energy-saving technologies. As the requirements for energy saving become more urgent, semiconductor chips not only have to reduce their own energy consumption, but also take on the responsibility of reducing system energy consumption. Therefore, in addition to providing a single energy-saving chip for electronic systems, semiconductor companies are also committed to providing customers with complete energy-efficient solutions.
If we take the liberty to ask a zoologist about the inevitable connection between the polar bear and the semiconductor chip, the other party will certainly be overwhelmed. However, in recent environmental protection and energy-saving propaganda, a picture may have left a deep impression on many people: the blue sea, floating icebergs, and a lonely polar bear, are also at a loss. Indeed, global warming is threatening every creature on the planet. As a fast-growing high-tech, should semiconductor technology make a difference?
Three major factors promote energy conservation needs
Reducing carbon emissions to suppress climate warming is the primary goal of energy conservation. Of course, human fraternity is not limited to polar bears, but also their own money bags. Since resources are limited, energy consumption means the loss of real money, so improving energy efficiency is also an important means of increasing revenue and expenditure. 10,000 steps back, even if resources and money are inexhaustible, the practical application of electronic products will also require energy saving. Consumers always demand to extend the standby time of portable electronic products as much as possible, and the system is low in energy efficiency. Excessive heat dissipation also greatly affects the performance of some electronic products. Therefore, environmental protection, economic benefits and practical application needs are the three major factors that promote the development of energy-saving technologies.
According to statistics, in the global power consumption, the electric motor is a well-deserved energy consumption “big householdâ€, which consumes 51% of electric energy, followed by lighting and air conditioning, respectively, consuming 19% and 16% of electric energy, which may be interesting. Unexpectedly, in the remaining 14%, the power used for the processing, transmission, and storage of information accounted for the vast majority. Hans Wildlen, executive vice president of Media Storage at Spansion, told the China Electronics News that due to the popularity of the Internet, from 2000 to 2005, the global Internet data center's energy consumption doubled from 710 per year. The billion kWh has risen to more than 150 billion kWh. At present, the global Internet data center has consumed more electricity than Iran, Sweden and Turkey. Jonathan Audy, a partner and technical director at ADI, said that 40% of the energy stored in the server room is the cooling system used for the equipment, so the energy consumption of the equipment itself For every 1 watt saved, you can save up to 0.67 watts of energy for cooling.
As the "darling" of the scientific and technological community, semiconductor technology is duty-bound to undertake the task of "saving the polar bear." JonathanAudy believes that the importance of advances in semiconductor technology for energy conservation lies in at least two aspects: through the improvement of product design and production process, the power consumption of the semiconductor device itself can be effectively reduced; more importantly, the use of semiconductor chips, The energy efficiency of other components of the system can be directly or indirectly improved. In the whole process of energy transfer and use, the semiconductor chip can usually monitor, adjust, optimize and control.
Semiconductor companies
In response to the energy crisis, governments and civil society organizations in many countries have put forward energy conservation and environmental standards and regulations, such as the US "Energy Star", "1 watt" program, "80PLUS", etc., semiconductor companies are focusing on satisfying consumers' product functions and At the same time of performance requirements, we must also carefully consider how to meet these energy-saving and environmental protection specifications.
For Internet data centers, Spansion has developed EcoRAM, a new storage product based on MirrorBit flash technology. According to HansWildenberg, EcoRAM will help the energy consumption of Internet data center servers by 75%, and under the same energy consumption conditions. The storage capacity is four times that of a conventional pure DRAM (Dynamic Random Access Memory) type server.
At the same time, semiconductor companies have extended the energy-saving reach to the details of people's lives. According to estimates, the average household will shift its energy consumption from induction cooking to induction heating, which will reduce energy consumption by 50%. Fairchild Semiconductor's 1200V field-stop trench IGBT (Insulated Gate Bipolar Transistor) series of devices are system designers for electromagnetic induction heating applications. Provides an efficient solution. These IGBTs combine field-stop structures with avalanche-resistant trench gate technology to provide the best trade-off between conduction and switching losses for maximum efficiency. Claudia Innes, director of Fairchild Semiconductor's marketing, said in an interview with China Electronics News that this solution can reduce conduction loss by 25% compared with traditional NPT (non-transmissive) trench IGBT devices. Switching losses and drastically reduce system operating temperatures; system reliability is enhanced due to reduced cooling requirements, and total system cost is also reduced; in addition, these devices are built with fast voltage optimization (ZVS) technology optimized Recovery diodes (FRD) reduce the number of components required.
Freescale Semiconductor has an edge in automotive energy efficiency, providing advanced embedded controllers, sensors, power management components and power brakes for vehicles. Engine control technology is also an area of ​​focus for Freescale, such as hybrid vehicle control and diesel engine management for common lines that have been introduced into emerging applications by the company.
Solution enhances energy savings
In addition to providing a single energy-saving chip for electronic systems, the world's leading manufacturers are also committed to providing customers with complete energy-efficient solutions, from power management, data conversion, operational amplification, interface circuits and audio and video systems. Optimized chips and patented technology. In this way, the various components of the system can more effectively exert their energy-saving effects, thereby achieving the "1+1 2" effect.
National Semiconductor uses its PowerWise family of products to provide different system solutions for multiple applications. Huang Hanji, director of the company's Asia-Pacific power products market, told this reporter that such system solutions will integrate the company's patented technology and use it in chips or by licensing. "In order to facilitate customers' reasonable trade-offs between performance and power consumption, National Semiconductor has also developed a set of PowerWise performance indicators to help system design engineers more easily compare the energy efficiency of different analog components and subsystems, so as to make reasonable choices. Huang Hanji added. In portable applications, PowerWise will provide energy-efficient products for display, RF systems, power management systems, lighting systems, audio equipment and multimedia systems; in the fields of industrial electronics, general lighting and wireless infrastructure, PowerWise solutions are also available. Excellent performance.
NXP Semiconductors' PC (Personal Computer) power supply energy efficiency solution is another example. In July of this year, the company announced that its GreenChipPC chip successfully met the "80PLUSGold" certification requirements for reference designs, which will make the overall efficiency of the PC desktop power reference solution more than 90%. Compared to the average power consumption of today's regular desktop PCs, desktop PCs using this solution can reduce energy consumption by 50%. NXP expects that if 160 million desktop computers use a solution that meets the "80PLUSGold" certification requirements, It can reduce emissions of 200 million tons of carbon dioxide.
