What are the development difficulties and development prospects of the switching power supply industry
As an indispensable device for electrical equipment, switching power supply has many application fields, and there is no substitute device, so the market scale is huge. In 2016, the scale of China's power supply market exceeded 200 billion yuan for the first time, reaching 205.6 billion yuan, a year-on-year increase of 6.9%. In 2018, the scale of China's power supply market reached 245.9 billion yuan, a year-on-year increase of 5.95%. will increase to 422.1 billion yuan.
The development dilemma of switching power supply industry:
(1) Lack of comprehensive professionals
The field of switching power supply involves many technical fields such as power electronics, semiconductor devices, frequency conversion technology, electromagnetic technology, computer (microprocessor) technology and comprehensive automatic control. At present, the accumulation of talents in the industry is relatively lacking. compound talents, and the above-mentioned compound talents need a long time to be cultivated. Therefore, the relative lack of comprehensive professional talent reserves has become one of the challenges for the development of my country's switching power supply industry.
(2) The technical level of server power supplies in mainland China needs to be further improved
Due to the late start of server power supply enterprises in mainland my country and their weak foundation, there is a certain gap between the production process and technical level of server power supply enterprises in mainland my country and the international advanced level. Some upstream semiconductor and other raw material markets are mainly occupied by foreign manufacturers such as Europe, America and Japan. The development of my country's server power supply enterprises has formed certain restrictions, which affects the development process of domestic enterprises in the international market.
Development prospect of switching power supply industry:
(1) National policies strongly support industrial development
As a basic, strategic and leading pillar industry of the national economy, the electronic information industry has become an important support for the transformation and upgrading of my country's manufacturing industry. As an essential part of electronic equipment, switching power supply is the key to ensure its stable and reliable operation, and it is an important part of China's electronic information industry. "Made in China 2025" proposes that intelligent manufacturing is the main way to enhance the overall competitiveness of China's manufacturing industry, which is the core content of Industry 4.0. Among them, big data and cloud computing are the key development areas of the country. In addition, my country's downstream office electronics for switching power supplies The application fields have put forward corresponding policy requirements for energy saving and consumption reduction, and will continue to promote a new round of switching power supply technology innovation and industrial transformation. Therefore, switching power supply products will be driven by policies and maintain a good development trend.
(2) China's electronic information manufacturing industry is developing rapidly
According to the "Operation of Electronic Information Manufacturing Industry in April 2020" released by the Ministry of Industry and Information Technology, from January to April 2020, the operating income of the electronic information manufacturing industry above designated size decreased by 1.6% year-on-year, the total profit increased by 15% year-on-year, and the operating income profit margin was 3.39%. %, operating costs decreased by 2.1% year-on-year. At the end of April 2020, notes receivable and accounts receivable of the entire industry increased by 7.9% year-on-year.
In terms of product structure, the development of high-end and intelligent products has achieved remarkable results. Emerging products such as smart wearables, virtual reality equipment, and smart homes have accelerated their growth. New technology products such as quantum dot TVs, OLED TVs, and laser TVs have sprung up. Domestic CPUs are used. The "Sunway? Light of Taihu Lake" became the world's first supercomputer with a computing speed exceeding 1 billion billion operations per second.
(3) Continuous upgrading of switching power supply technology
With the development of power electronics technology, the requirements for the appearance and structure of products in the downstream industry are constantly developing in the direction of portability and miniaturization, and the performance is developing in the direction of networking and intelligence, which also raises higher requirements for the performance and appearance of switching power supplies. Promote the continuous innovation of switching power supply technology. In addition, new power devices and new circuit topologies are constantly updated, which promotes the R&D and production of switching power supplies with high frequency, high reliability, low energy consumption, low noise, anti-interference and modularization, so that they can better meet the downstream market requirements for products. Demand for portability and efficiency. At the same time, as more and more electronic products including laptops, desktops, and tablets use USB Type-C interfaces, the design standards of power adapters also need to be gradually updated.
(4) Continuous expansion and deepening of the application field of switching power supply products
Switching power supply products have been widely used in many fields such as office electronics, set-top boxes, network communications, security monitoring, audio, financial POS terminals, data centers, power tools, etc. There are many downstream industries, and the market demand space is broad, not affected by the development of a single industry or a few The constraints of the customer's operating conditions. With the gradual penetration of Internet technology in various fields, and the gradual deepening of big data and cloud computing applications, switching power supplies will have more important applications in artificial intelligence, medical care, new energy, automotive electronics, biometrics and other fields. Demand will grow steadily.
