The development trend of switching power supply industry

　　The development trend of switching power supply industry

　　Greening

　　Green switching power supply products will be widely used. Green switching power supply products specifically refer to significant energy saving and no pollution to the electricity network. The nodes and environmental protection requirements of the 21st century will enable a variety of intelligent switching power supply technologies to be widely used, and the power supply structure will develop from centralized to distributed.

　　miniaturization

　　Small high-frequency switching power supply and its technology have become the mainstream of modern power supply systems. Miniaturization and weight reduction of power supplies are particularly important for portable electronic devices (such as mobile phones, digital cameras, etc.). Therefore, improving the power density and power conversion efficiency of the switching power supply, making it smaller and lighter, is the goal that people are constantly striving to pursue. As one of the main technical means of power supply miniaturization, high-frequency and soft-switching technology has become one of the hotspots in the international power electronics industry in recent years.

　　Digitizing

　　The digital power supply combines the high efficiency of the switching power supply with the intelligent control of the digital chip, and uses appropriate algorithms to adjust the voltage and current. Compared with analog power supply, digital power supply can carry out accurate digital correction of current detection error, and voltage detection is more accurate; it can realize fast and flexible control design.

　　Integrated

　　In order to improve the reliability of the system, it has become a trend for the whole machine manufacturer to cooperate with the component manufacturer to develop "user-specific" power modules. That is, almost all the hardware of a complete machine is installed in a module in the form of a chip, so that a large number of components are no longer connected by traditional leads, and the parasitic parameters are minimized, thereby reducing the power components and power The electrical stress that the device bears is reduced to a minimum to achieve the purpose of improving the reliability of the system equipment.

　　market expectation

　　The China Power Supply Society and ICTresearch predict that in 2011, the output value of China's power supply industry will grow to 130.4 billion yuan, an increase of 11.26% over 2010. In 2015, the output value of China's power supply industry will reach 215.6 billion yuan, with an average annual compound growth rate of 13.39% from 2011 to 2015.

　　With the gradual development of power supplies in the direction of miniaturization, thinning, light weight, and high frequency, it can be expected that the output value of light, thin, small and high-frequency switching power supplies in the future will be higher than that of the entire power supply industry. The Chinese Power Supply Society predicts that by 2011, the output value of switching power supplies in the country will reach 128 billion yuan, and in 2015, the output value of switching power supplies in my country will reach 187.5 billion yuan.

　　service

　　In the future, more and more overall product manufacturers will outsource customized power supply business, and use external excellent professional teams to undertake their business, so as to focus on core business to reduce costs, improve efficiency, and enhance the core competitiveness of the enterprise and external links. Resilience. Under this trend, more OEM/ODM manufacturers will regard service as their competitiveness. With the acceleration of information exchange, the prices of products on the market tend to be open. If power supply manufacturers want to obtain orders from manufacturers, they need to provide valuable value-added services. Design service is one of the most important value-added services for flat-panel TV power supplies, especially to provide customers with practical solutions. In the customized power supply manufacturing industry with relatively strong technical requirements in the industry, design links are added to the value chain from OEM to ODM. Extend to the upstream of the industrial chain and gradually occupy high-end value-added links. Good design ability and fast-response logistics will become the key to winning customers.

　　In addition, speed up the processing speed of order delivery, as well as after-sales quality service, close to and assist customers in solving problems, and improve the professionalism of technical services. Grasp the project development progress of major customers, strengthen the speed of technical service support and the speed of new product development. Strengthen the auxiliary control of the quality of outsourcing products. Shortening the program development time of leading new products is a manifestation of the high-quality services of future manufacturers.
