At present, power supply is widely used in various industries and is an important foundational technology. Luo Baihui stated that in the coming period, power supply will develop towards green, small, high-frequency, efficient, diversified, and integrated directions, and China's power supply industry will also become more mature.



Development trend of switch mode power supply products

Greenization

Green switching power supply products will be widely used. Green switching power supply products specifically refer to significant energy savings and no pollution to the power network. Node and environmental requirements will enable the widespread application of various intelligent switching power supply technologies, leading to the development of power supply structures from centralized to distributed.

Miniaturization

Small high-frequency switching power supplies and their technology have become the mainstream of modern power supply systems. The 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 switch mode power supplies, making them miniaturized and lightweight, is a goal that people are constantly striving to pursue. High frequency and soft switching technology, as one of the main technical means for miniaturization of power supplies, has been a hot research topic in the international power electronics industry in recent years.

Digitization

Digital power supply combines the efficiency of switch mode power supply with the intelligent control of digital chips, and uses appropriate algorithms to adjust voltage and current. Compared with analog power supplies, digital power supplies can accurately correct current detection errors and voltage detection is more accurate; It can achieve fast and flexible control design.

Integration

In order to improve the reliability of the system, it has become a trend for whole machine manufacturers to collaborate with component manufacturers to develop "user specific" power modules. That is to install almost all the hardware of a complete machine in the form of chips into a module, so that a large number of components are no longer connected by traditional leads, minimizing parasitic parameters, and thus minimizing the electrical stress borne by power components and power devices, achieving the goal of improving system equipment reliability.

Market Outlook Forecast for Switching Power Supply

In 2011, the output value of China's power supply industry will increase to 130.4 billion yuan, an increase of 11.26% compared to 2010. In 2015, the output value of China's power supply industry will reach 215.6 billion yuan, with a compound annual growth rate of 13.39% from 2011 to 2015.

As power sources gradually move towards miniaturization, thinness, lightweighting, and high-frequency, it can be expected that in the future, the growth in output value of light, thin, small, and high-frequency switching power supplies will be higher than that of the entire power supply industry. The China Power Supply Society predicts that by 2011, the national output value of switching power supplies will reach 128 billion yuan, and by 2015, the output value of switching power supplies in China will reach 187.5 billion yuan.
