The development of electronic transformers towards miniaturization
2024-05-13 2793In recent years, the electronic transformer industry has undergone significant changes in its operating mechanism to meet the needs of the market economy and supporting facilities. According to industry association statistics, private enterprises account for about 50% of the electronic transformer industry. At present, the electronic transformer market in China is basically in a stable state. Due to the labor-intensive nature of electronic transformers, labor costs in China are relatively low, and the industry has not been greatly impacted. On the contrary, there has been further growth in exports. Last year, the export value of electronic transformers in China reached nearly 1.2 billion yuan, a year-on-year increase of 2.66%. Our country's electronic transformer products are still mostly traditional products produced for decades, mainly using silicon steel sheets, ferrite, enameled wires, plastic frames, and other raw materials and components. In order to support new electronic products, R-type iron core technology has been introduced in recent years, and R-type transformers have been developed, further improving the quality level of electronic transformers.
Electronic transformers are one of the large and heavy components in electronic products. In order to meet the needs of miniaturization development of electronic products, the market will inevitably drive electronic transformer products to develop in the direction of light, thin, and small. More importantly, with the change of overall performance, it will drive electronic transformer products to develop in the direction of high-frequency, low loss, surface mount, new materials, and new structures of new transformers.
In the coming years, the technological development trend of electronic transformers is towards miniaturization of products. At present, the development of miniature electronic transformers in foreign countries is rapid, with the production of 5mm x 5mm miniature transformers and flat transformers with a thickness of only 0.2mm. A few foreign-funded enterprises in China already have such packaged miniature electronic transformers, while domestic enterprises still need to develop them. Microminiaturization is the development trend of new products.
Piezoelectric ceramic transformers have been widely used abroad, especially in LCD displays.
The production of piezoelectric ceramic transformers will change the traditional production method of transformers. The main raw materials, magnetic materials, enameled wires, etc. will be replaced by ceramic materials, which will fundamentally change the processing technology of these transformers.
China's electronic transformer production accounts for over 20% of the global total production, and has become a major supply base for the international market. With the increasingly fierce international market competition, in order to reduce costs, it is necessary to further promote the scale of transformer production, form economies of scale, and adapt to more intense market competition.
Transformers are products customized according to user requirements, and enterprises must keep up with the development trend of user products. The development of new transformer products must be combined with the development of new products and the application of new materials, as well as the development of non-standard instruments and equipment.
