As energy and environmental issues are increasingly valued around the world, coupled with tight energy supplies and growing demand, semiconductor suppliers are playing a more active role in driving energy efficiency. Fairchild Semiconductor is currently focused on enhancing R&D, implementing useful acquisition strategies, and changing its business model in manufacturing to develop next-generation solutions that further increase power efficiency.
MarkThompson, President and CEO of Fairchild Semiconductor, said: "China is fully aware of the challenges facing the country and needs to strike a balance between economic development and the protection of the local and global environment. According to the China Energy Information Administration Carbon Chelation Leadership Forum According to the Carbon Sequestration Leadership Forum, total global energy consumption is expected to increase by 57% from 2002 to 2025, and China is expected to consume 14.2% of global energy by 2025. Simply trying to curb demand for energy is not Practically, because in China, the use of personal computers doubles every 28 months, and the power consumption of household white goods such as refrigerators and air conditioners currently accounts for about 10% of China's total energy demand."
“China’s energy consumption is faster than gross domestic product (GDP), which represents a daunting challenge to achieve national sustainable development goals. Power semiconductor suppliers and power engineers can help China meet energy challenges and are doing their best. Achieving the goal. Today's semiconductor products can truly achieve energy savings and energy efficiency while meeting the market's demand for higher performance, lower cost and smaller size products."
Guo Yuliang, president and managing director of Fairchild Semiconductor Asia Pacific, said: "With the approach of the 2008 Beijing Olympic Games, the government has set a new target of reducing energy consumption per unit of GDP and water consumption by 5%. Especially in the hotel industry, The goal is to reduce energy consumption by up to 10% by switching to more efficient lighting and installing approved energy-efficient air conditioners. This is an important area where Fairchild products can make a difference, and our products can improve energy efficiency. And to minimize power requirements. For example, if 923,000 households use an average of five 60-watt bulbs and now switch incandescent bulbs to CFL bulbs with Fairchild components, the energy saved will be more than 69,000 Lighting for the home."
Guo Yuliang added: "In addition, the 2008 Olympic Games has promoted the demand for energy-efficient communication and broadcasting equipment. We have seen the market for LCD TVs, plasma displays, rear projection TVs (PTV), outdoor TVs (ODTV) and set-top boxes. Demand has increased dramatically. All of these products must meet China's stringent energy efficiency and standby power requirements."
Increasing power efficiency is a problem for all types of electrical equipment, and each product has its own design challenges in terms of space, system cost, performance and power level. Energy-efficient technologies can create for lighting, motor control and power products. Unique advantages.
?illumination
The challenge: to increase efficiency, extend life, improve quality of life and provide greater flexibility.
Solution: Replacing incandescent lamps with fluorescent, LED or HID lamps can dramatically increase energy efficiency by 85%. Integrated ICs such as MOSFETs and IGBTs reduce component count, reduce overall cost, simplify ballast design, reduce switching losses, and increase dimming capability.
Electronic commutator motor
Challenge: Improve efficiency, simplify design, and reduce system cost.
Solution: Converting from a single-phase AC motor to a variable speed DC motor saves 40%. Integrating IGBTs, MOSFETs, HVICs, and LVICs in an advanced package simplifies design and reduces time to market.
?power supply
Challenge: Improve efficiency and reliability, reduce standby power consumption, reduce size and reduce overall system cost.
Solution: An integrated power switch with soft switching reduces switching losses while simplifying design and reducing size. Advances and functional enhancements in semiconductor IC processes have helped power supply manufacturers meet the requirements of the 1 watt initiative. Techniques that reduce the controller's switching frequency also reduce switching losses at low output or standby power. In addition, certain functions to save energy such as power factor correction circuitry can be turned off during standby. Low gate charge FET switches also reduce losses.
Thompson pointed out: “Because of the shortage of energy supply and the growing demand, the role of semiconductor suppliers in promoting energy efficiency is very important. We must continue to develop next-generation solutions that can further improve energy efficiency. Although the government and related agencies have introduced new ones. The specification aims to solve these global problems, but people still need to do more to promote the popularity of energy-saving products."
