Miniaturized electronic transformers or new enthusiasm for industrial development

Due to the fierce competition in the domestic market, the bid price was lower than the cost price, leading some companies to start overseas routes, export products, and build factories abroad. In addition, many companies have begun to develop new, energy-saving, environmentally friendly, intelligent products. However, the general economic benefits of domestic transformer companies have been significantly reduced, and many companies are at the edge of losses or losses. A large number of distribution transformer enterprises have even experienced the situation of sacrificing product quality at the expense of malicious competition (profit margin in the third quarter of 2011 decreased by 46% year-on-year). "Aluminum substitutes for copper", contract fraud, aluminum wire can be used as a transformer coil "reuse of the secondary piece", magnetic performance, surface insulation, loss, excessive noise, transformer capacity "short of short of two", which is not conducive to the market The behavior of the rules makes the “short board” of transformer market appear more and more.

Towards the transformation of miniaturization to meet the needs of the long-tail market

The transformer has a history of more than 140 years, has a long history, and the industry's technological improvements have allowed it to regain market confidence. Shang Pu consulting electronics industry analysts pointed out that the application of electronic products is constantly expanding, the prospects of the electronic transformer industry is also very good. Electronic transformers are one of the largest and heavier parts in electronic products. In order to meet the miniaturization and development requirements of electronic products, the market has begun to 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. It is understood that high-frequency, low-loss, small-size, and low-cost electric transformers are the best-selling products on the market.

Although traditional old products have a market and output, the profit margin is very small, and it is impossible to form a strong competitive power. The main profitability of transformers lies in a new generation of high-end products, the rapid rise of passive integration technology, and mini-chips The comprehensive upgrading of the machine products provides transformer enterprises with a technological breakthrough point for achieving leap-forward development, and it is also an electronic transformer enterprise that will certainly take the road of technological progress in the future development.

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, industry insiders predict: the miniaturization of electronic transformers will be the development trend of new products in the future.

Electronic Transformer Industry Rejuvenated High-frequency Markets Desire Despite the decline in the quality of transformer products and the increase in accident rate, the industry has become “wild” status, but market demand still determines the rise of another area of ​​transformers. In contrast, China’s electronic transformer market has a large prospect. The so-called electronic transformer is a non-regulated switching power supply. The principle is to first rectify AC power into DC power, and then use electronic components to form a high-frequency oscillator to convert DC power into high-frequency AC power. , The voltage required by the output of the switching transformer is then rectified for use by the appliance.

Because of its advantages of small size, light weight and low price, it is widely used in various electrical appliances. It is understood that 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.

According to incomplete statistics, there were nearly 3,000 factories producing electronic transformers in 2007, with an annual sales income of 25 billion yuan, and hundreds of product varieties, which can be used for supporting various kinds of complete machines and have become one of the world’s largest manufacturers of electronic transformers. 60% of the output of electronic transformers is used to meet the needs of the international market. At present, the demand for consumer electronics products is becoming more stable and the production of electronic transformers is slowing down; however, due to the use of high-frequency electronic products such as audio and video, office automation and communications, etc. With the increase in popularity and demand, the demand for high-frequency electronic transformers will continue to grow.
