The current development environment facing power module customization

Power supply module, also called module power supply, is an electronic product that provides working current for electronic products. Many unfamiliar people often confuse it with the commonly used backup power supplies, lithium batteries, or mobile power supplies. But they are two different concepts.Power module customizationIt does not have an energy storage module and does not provide the function of electrical energy storage. The power supply is an electronic product that provides working current for electronic equipment, and at the same time is responsible for the functions of voltage transformation, isolation, filtering, etc., in simple terms, it is the transformation of voltage and current!

At present, the development of power module customization has been relatively mature, and the main development environment has the following points:

1. Standard environment. For an industry to develop rapidly, standards are indispensable. The power module also has specific technical requirements to improve the quality of the power module! At present, the international and domestic power supply industries have formulated a number of standards, which mainly stipulate the production technical requirements, experimental methods, inspection and packaging specifications of power modules, and other special process requirements to improve product reliability. The main standard of "EN 50155" is the modular power supply for the railway industry; in the communications industry, the main standard is to meet the technical standards of "EN 55022"; the main standard for modular power supply in the power industry is to meet "EN 62040"; in the medical industry Module power supply, the main standard is to meet "EN 60601".

2. Policy environment. The module power supply integrates electronic power technology, small intelligent control theory, electronic compatibility design, electromagnetic component design, thermal design, packaging design and other technologies. It is the basis for ensuring information security, ensuring the stable operation of electronic products, and the process of industrial automation. , Has received multiple policies and policy support from multiple industries. Compared with traditional power products, modular power supplies can be adapted to various harsh working environments, easy to use, and easy to maintain. They are widely used in railways, electric power, communications, aerospace, automobiles, ships, electronic information, new energy, industrial control, Fire fighting, instrumentation, medical treatment, transportation vehicles and other fields. The electronic information industry, aerospace, new energy and other application fields are industries that the national plan preferentially encourages development and are supported by national policies. In particular, it plays an irreplaceable role in the electronic fields of high reliability and high technology. Play a very important role in the development of industrial automation!

3. Environmental protection technology environment. With the large-scale application and scrapping of electronic products, many electronic products in the past have a certain impact on the environment or the human body. So now Europe and the United States have very strict requirements on electronic products. Can not contain common toxic substances, more and more types, higher and higher requirements for content. There are also terms related to product performance, such as pollution restriction, recyclability, and energy saving. For example, the EU launched the IS014000 environmental management system, which requires imported products to meet environmental protection standards from production preparation to manufacturing, sales, use and disposal. There are also "UL GG" and "Green Cross" in the United States, "ECP" in Canada, etc. To this end, they have also formulated strict product quarantine and inspection systems.

4. Technical environment. Judging from the current technological development of power supply module customized products, the upstream industry technology is constantly changing with the requirements. For example, electronics, new technology, nano-application progress, and the use of new materials, in line with the various new needs of high-end equipment and users, modular power supplies will continue to develop in the direction of miniaturization, functional modularization, systemization, and chipization. It is mainly reflected in the development of high performance, high integration, high precision, high reliability, high radiation resistance and low power consumption. At the same time, with the fierce competition in the same industry, the cost of products must be further controlled, and the materials used are more It is required to be environmentally friendly, durable and safe. Especially in the European and American markets, the product requirements for power modules are constantly improving. For China, which is lagging behind Europe, America and Japan, we need to continuously improve product design and adopt more advanced production and cost control before we have the opportunity to strive for it. To a certain market advantage!
