The development of electronic transformers in the direction of miniaturization

In order to adapt to the market economy and supporting needs, the electronic transformer industry has undergone a major transformation in recent years. Statistics from industry associations show that private enterprises already account for about 50% of the electronic transformer industry. At present, China's electronic transformer market is basically in a stable state. Because electronic transformers are labor-intensive products, China's labor costs are relatively low, and the industry has not been affected by a greater impact. However, exports have seen further growth. Last year, China’s exports of electronic transformers approached 1.2 billion yuan, an increase of 2.66% year-on-year. China's electronic transformer products are still mostly traditional products that have been produced for several decades. They are still using silicon steel sheets, ferrites, enameled wires, and plastic skeletons as their main 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 to further improve the quality of electronic transformers.

Electronic transformers are one of the bulky and heavy components in electronic products. In order to meet the miniaturized development requirements of electronic products, the market will surely promote the development of electronic transformer products in the direction of lightness and thinness, and more importantly, with the performance of the whole machine. Changes will certainly drive the development of electronic transformers to new types of transformers with high frequency, low loss, surface mount, new materials, and new structures.

In the next few years, the technological development trend of electronic transformers is the development of products to miniaturization. At present, the development of foreign micro-electronic transformers is rapid, and 5 mm×5 mm×5 mm micro-transformers and planar transformers with a thickness of only 0.2 mm have been produced. A few foreign-funded enterprises in China already have such miniature electronic transformers packaged, while domestic companies still have to wait. Development. Miniaturization is the development trend of new products.

Piezoelectric ceramic transformers have been widely used abroad, especially in liquid crystal displays.

The production of piezoelectric ceramic transformers will change the traditional production methods of transformers. The main raw materials, magnetic materials and enameled wires will be replaced by ceramic materials, which will cause a fundamental change in the processing technology of this part of the transformer.

China's electronic transformer production accounts for more than 20% of the world's total output. China has become the main supply base for the international market. With the increasingly fierce competition in the international market, in order to reduce costs, it is bound to further promote the scale of transformer production, the formation of economies of scale, to adapt to more intense market competition.

Transformers are customized products based on user requirements. Enterprises must keep up with the development trend of user products. Transformer new product development must be combined with new machine product development and the use of new materials, combined with the development of non-standard equipment.
