Information

The invention of the transformer has a history of more than 140 years, and it has developed with the rapid development of electronic technology, and has also been accompanied by a series of product upgrades.

Due to the characteristics of low price and convenient manufacturing, E-type and UI-type chip transformers are widely used, but the products of this structure are heavy, and C-type and toroidal wound iron-core transformers were born, and soon became popular in various industries. This kind of electronic machine has been widely used, but the C-type transformer is noisy, the core processing technology is more complicated, and the quality consistency is poor, which is still a fly in the ointment.

In the 1990s, the R-type circular section iron core was successfully developed, which fundamentally solved the problem of transformers. The R-type transformer has the advantages of extremely small leakage, low loss, low temperature rise, extremely low noise, simple structure, safety and reliability, so it has a variety of uses in various fields, and will gradually replace the traditional E-type, C-type and toroidal transformers. The new revolution known as the transformer of the 90s.

As the demand for consumer electronic products becomes more stable, the production and development of electronic transformers have slowed down; however, due to the popularity and demand growth of high-frequency electronic products such as audio and video, office automation and communications, the demand for high-frequency electronic transformers Growing. High frequency, low loss, small size and low price power transformers are the best selling products on the market today.

The market size of the world's electronic transformers is basically maintained at about 5.5-6 billion US dollars, accounting for about 6.5% of the world's total electronic components market. Japan's production and consumption accounted for about 43% and 40% of the world market, respectively, the United States accounted for about 17% and 22%, while the share of other Asian countries and regions rose rapidly, at about 13% and 8%.

Since electronic transformers are labor-intensive and user-customized products, there are few standard products, and it is difficult to achieve economies of scale in production. In addition, the market competition is becoming increasingly fierce and prices continue to drop. Production has shifted to areas with low labor costs. The development of electronic transformer production brings opportunities.

Hong Kong businessmen have set up factories in China to produce electronic transformers, and most of the products sold in the Hong Kong market are produced in the mainland. Since the labor cost of producing electronic transformers in Taiwan is many times that of the mainland, many Taiwanese businessmen set up factories in the mainland, which greatly improves the competitiveness of their products in the international market. Foreign businessmen such as Japan and Singapore have also set up many foreign-funded enterprises in my country. In addition to the development of original domestic production enterprises, my country has become one of the main production bases of electronic transformers in the world.

In 1998, domestic electronic transformers and their parts were exported to more than 70 countries and regions, earning 727 million US dollars in foreign exchange, with a surplus of more than 300 million US dollars.

From January to June 1999, 1.09 billion electronic transformers were exported, earning 380 million US dollars, a year-on-year increase of 12.2%. Among them, 1.09 billion electronic transformers with p<1KV were exported, earning US$318 million in foreign exchange, a year-on-year increase of 10.2%; foreign exchange for parts was US$60 million, a year-on-year increase of 21.3%; 1KV<P<16KV products were exported 720,000 pieces, earning 4.549 million US dollars in foreign exchange, a year-on-year increase of 49.6%.

It can be seen that the relationship between domestic electronic transformers and the world market is getting higher and higher, and its development is largely driven by exports. However, due to the introduction of its technology and equipment mainly from Japan and my country's Hong Kong and Taiwan regions, the concentration is strong and the generality is not enough; the products are mainly low-end, general-purpose, less customized by users, low in added value, and low in export prices. ; In addition, the export of products is mainly through the intermediary of foreign trade companies or joint ventures, which makes domestic electronic transformers less competitive in the international market, affecting the development and market development of electronic transformers.

Even so, product export is still a big market for my country's electronic transformer manufacturers to survive and develop. From 1994 to 1998, the foreign exchange earned by electronic transformer exports doubled.

In 1998, China imported electronic transformers and their parts from more than 60 countries and regions, with a foreign exchange of 422 million US dollars, an increase of 133% over 1994.

The electronic transformers produced by domestic foreign-funded enterprises are directly supplied to the foreign-funded enterprises that produce complete machines, which are equivalent to imports in customs statistics (exports are not counted), so there are import values ​​from the Republic of China in customs statistics. In 1998, it accounted for 11.8% of the domestic import value, and the localization rate will gradually increase in the future, but it is difficult for most domestic enterprises to have the opportunity.

From January to June 1999, 356 million electronic transformers were imported, and the foreign exchange was 230 million US dollars, a year-on-year increase of 20%. Among them, p<1KV imported 331 million pieces, with a foreign exchange of 113 million US dollars, a year-on-year increase of 16.4%; parts with a foreign exchange of 115 million US dollars, a year-on-year increase of 24.8%.

From 1994 to 1998, the market scale of domestic electronic transformers showed a steady growth trend. The scale of production mainly depends on the demand in the international market and the export of domestic products. The growth rate of imports is greater than the growth rate of production and exports. In 1998, the domestic production and export scale of electronic transformers reached 873 million US dollars and 620 million US dollars respectively, and their parts reached 1.04 billion US dollars and 727 million US dollars; the market size was 466 million US dollars, with an average annual The development speed is 11.4%, and the market size of its parts has reached 733 million US dollars. It is estimated that in 2000, the domestic market size of electronic transformers will reach 800 million US dollars, the production scale will exceed 1 billion US dollars, the export will be more than 800 million US dollars, and the import will be nearly 500 million US dollars.

Imported products account for 45.7% of the total domestic electronic transformer market capacity, and the import of parts has accounted for 57.5%. The domestic market and production have been fully integrated with the international market.

Exports did not benefit most domestic enterprises. Before 1998, the electronic transformer industry in the electronic system suffered losses year after year. The main reason was that more than 90% of domestic enterprises were small enterprises with backward production methods and technical content of products. low and lack of competitiveness.

In the industry, foreign-funded enterprises already have a clear advantage. In 1998, the total sales revenue of 145 enterprises in the electronic system was 7.35 billion yuan, the sales profit was 1.07 billion yuan, and the tax paid was 260 million yuan. The total profit It is 361 million yuan, and the economic benefits of the industry have improved significantly compared with previous years. The sales revenue of foreign-funded enterprises has accounted for 44.4% of the total sales revenue of the industry; among the 16 enterprises with sales revenue exceeding 100 million yuan, there are 10 foreign-funded enterprises, including 4 wholly-owned enterprises.

The development goal of the world's electronic transformer technology is light weight, high efficiency and high density; chip products will be further developed, but the market share will not be too high. Flyback transformers for high-definition TVs and high-frequency displays are one of the main areas that manufacturers pay attention to, and the demand for loopless flyback transformers will increase significantly. Power transformers with high frequency, low loss, small size and low price will be the darling of the market. The market prospect of high voltage power transformers is encouraging, and production automation is also one of the main focuses of electronic transformer manufacturers.

Judging from the development trend of electronic transformer technology in the world, many small domestic enterprises have faced bottlenecks in their existing products and technologies. Low-end products, outdated technologies, and lack of funds will not be able to gain a foothold in the fierce market competition in the future. Large and medium-sized enterprises can also introduce production technology, but the production technology and equipment introduced successively since the 1980s have fallen behind with the passage of time. Generally speaking, the products of domestic domestic-funded enterprises are at the low-end level; the production technology and equipment of the three-funded enterprises are mainly imported.

At present, although China is one of the main production bases for medium and low-grade electronic transformers in the world, most domestic-funded enterprises cannot obtain orders for customized products from foreign users, and their exports are limited. Retrofit. Therefore, domestic-funded enterprises have gradually lost their dominant position in China, and the rapid development of industry leaders has accelerated the polarization of enterprises, and the situation of many small enterprises will be more difficult.

Due to the specific domestic conditions, the development prospect of the electronic transformer industry is still good. The competition in the future will mainly be the competition between the domestic-funded industry leaders and foreign-funded enterprises, and many domestic-funded small enterprises are powerless. Strong alliances and asset reorganizations between enterprises will occur from time to time. Leading enterprises will accelerate technological transformation, adjust product structure, develop economies of scale, and improve management level and market share. It will be its main development strategy. good investment opportunity

Strong demand for high frequency and low loss electronic transformers

In recent years, the development goal of electronic transformer technology is light weight, high efficiency and high density, and chip products will also be further developed. Due to the continuous development of household appliances and electronic equipment, the demand for low-voltage electronic transformers is increasing. Therefore, flyback transformers for high-definition TVs and high-frequency displays have become the main areas of concern for manufacturers. Among them, loopless flyback transformers The demand for high-voltage power transformers will have a greater growth; high-frequency, low-loss, small-size, low-cost power transformers will also occupy a large market; the market prospect of high-voltage power transformers is encouraging.

At present, the market size of the world's electronic transformers is basically maintained at about 6 billion to 7 billion US dollars, accounting for about 7.5% of the world's total electronic components market. Among them, Japan's production and consumption account for about 43% and 40% of the world market respectively, the United States' production and consumption account for about 17% and 22%, respectively, and the production and consumption shares of other Asian countries and regions have risen rapidly, reaching 13% respectively. and around 8%.

Since my country's entry into the WTO, the domestic electronic transformer market competition has basically been in a stable state and has not been greatly impacted. This is because electronic transformer products are labor-intensive and mainly customized for user requirements. There are many varieties and specifications, many production batches and large quantities, so it is not suitable for automation and large-scale production. With the increasingly fierce market competition, in order to reduce costs, production is shifting to areas with low labor costs.

At present, the production of electronic transformers in my country presents the following characteristics:

1. The medium frequency transformer has large output and low price, and is mainly exported, which drives its rapid development. At present, the industry average price of intermediate frequency transformers in my country's electronic systems is 0.626 yuan per piece, but the average ex-factory price of most companies is between 0.20 and 0.30 yuan per piece, and the highest is about 1 yuan per piece. Since the products are mainly exported, their prices are completely determined by the international market. With the increasing popularity of digital audio electronic products and the wider adoption of integrated circuits, audio transformers are no longer used in new color TVs, and the market share of audio transformers is declining.

2. The market demand for power transformers is strong. Power transformers are labor-intensive products and are mainly produced by custom-made products. In recent years, domestic and foreign market demand has been strong, and they have become popular products with rapid development. According to statistics, in recent years, the production of power transformers in Taiwan is expected to increase by 50%, Hong Kong will increase by 20%, and India will increase by 25%. Communications, computers, and consumer electronics are its three main markets, among which the growth in communications demand will play a big role in driving it. The current global annual demand for power transformers has exceeded 10 billion US dollars. develop.

Japan's 6×6.6×3.5mm for LCD and CD, and 2.6×5×277mm series of surface-mounted power transformers for game consoles and tuners are still shifting to low labor cost areas, bringing good opportunities for domestic production development.

3. Overproduction of flyback transformers. At present, the decline in global demand for color TV receivers has seriously affected the production of flyback transformers in Asia.

There are about 6 manufacturers of flyback transformers in Taiwan, my country, and most of them have transferred their production bases to the mainland of the motherland. Since the flyback transformer is a labor-intensive product, it is difficult to produce it in Taiwan. In addition, LCD monitors do not need flyback transformers, and their development is ahead of CRT monitors. Therefore, mainland companies have begun to produce converters for LCD monitors. device. The development of flyback transformer products in Taiwan focuses on two aspects: one is to develop small flyback transformers for short-neck CRTs; the other is to enhance quality awareness, most manufacturers have obtained UL, CSA, VDE, CE, EMI and TCO Such certification as a major goal of improving product quality.

At present, Japan's flyback transformers have been oversupplied, mainly due to the oversupply of Japanese companies' Chinese factories. With a lot of investment into flyback transformer companies in mainland China, the oversupply situation will continue, and this situation is expected to continue for a period of time. Due to falling prices of flyback transformers for traditional TV receivers and PC monitors, Japanese manufacturers are focusing on the production of value-added products such as flyback transformers for projection TVs. In order to avoid price competition, most manufacturers have turned to the high-end product market. For example, Japanese media electronics companies have turned their focus to high-end flyback transformers for HDTV receivers and high-resolution monitors. Manufacturers are actively using their technology to develop high-end products in order to maintain their international competitiveness. JVC Corporation has developed a flyback transformer that integrates high-voltage design techniques and control circuitry, thereby changing product performance while reducing production costs. For example, HRCM11 is a dual-focusing flyback transformer used in pulse broadband modulation systems. It is equipped with a high-voltage control circuit and its horizontal scanning frequency is as high as 120kHz. In the PC monitor market, Hitachi has introduced flyback transformers for ultra-high-resolution monitors in the CAD/CAM field, with a horizontal scanning frequency of 130 kHz and a dynamic focus modulation with a focus potentiometer. Most companies are targeting the development of low-loss flyback transformers for use in energy-efficient television receivers, and work is underway to replace the traditional windings in flyback transformers
