With the growth of downstream dem of switching power supply in China, the reduction of manufacturing cost of switching power supply the support of various policies, all these factors are favorable for the development of switching power industry, with a promising future. At the same time, the switching power industry will also present a new trend in the new era.

Switching power supply is the main category of electronic power supply products, widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment other fields. According to the application field, switching power supply is divided into industrial power supply, consumer electronics power supply, communication switching power supply, PC switching power box other switching power supply.

In recent years, the sales volume of switching power supply in China has maintained an average growth rate of 7% - 10%, reaching 98.9 billion yuan in 2012, a year-on-year growth of 7.28%; the growth rate of sales revenue of switching power supply in China slowed down in 2013, with sales volume of 105.5 billion yuan; in 2014, the sales revenue of switching power supply in China was 112.9 billion yuan, a year-on-year growth of 7.01%; in 2015, the sales revenue of switching power supply in China was 1227% Billion yuan, up 8.67% year on year.

With the development of power supply products towards miniaturization, thinness, lightweight high frequency, it can be predicted that the output value growth of light, thin, small high frequency switching power supply in the future will be higher than that of the whole power industry. In the next five years, Chinas macro-economy will grow steadily, its industrial structure will continue to be optimized, infrastructure investment will increase, downstream dem will continue to be driven. According to the historical statistics of Chinas domestic switching power market scale the pull of downstream dem on the industry, it is estimated that the output value of Chinas switching power in 2022 will reach 204.2 billion yuan, the sales scale will reach 207.5 billion yuan.
