subject: Speed The Development Of Emerging Markets Electronic Components Urgent Breakthrough - Appliance [print this page] Electronic components as the basis of electronic information industry, its development impact on the process of the entire information industry. The 3G communications, consumer electronics and automotive electronics, the rapid rise of emerging markets, but also for the electronic components business has brought new technical challenges. How to respond to these challenges and to seize this rare market opportunity, we invite China Electronic Components Association (CLP per Association) of the branch of industry experts to discuss the Secretary-General and from which we can see that only the internal components and raw materials companies and whole enterprises upstream and downstream businesses work together, progress together, to stand in the future competition unbeaten.
Electronic transformer: with the common progress of upstream and downstream
Chinese Institute of Electronics Components Electronic Transformer Technology Branch of the Secretary-General Jiang Deqing
The past 30 years, almost all categories of electronic products are toward the high-frequency, high efficiency, low loss and high cost-effective direction, the traditional EI, C-type electronic transformer core smaller living space narrowing. Therefore, the electronic transformers in China mainland in the traditional production still accounts for a large percentage of cases, must be spirit of reform and innovation, increase the pace of its replacement, otherwise, the mainland's electronic transformer industry will be a long time to in a "working" status.
Going through three levels of replacement
In a sense, the electronic transformer industry in China is experiencing the replacement of three levels: first level is the three-dimensional transformer (the traditional common transformer) to the planar transformer of innovation, the size of planar transformer weight reduced than the traditional 80%, has formed 5W-20kW/20kHz ~ 2MHz of products, the efficiency of the typical value of up to 98%. The second level is the chip transformer update volume. Chip to further reduce the height of the transformer, the basic realization of the flat. They are more suitable for low-voltage current in the 100A high current power supply requirements. The structure of the primary winding of a number of commonly used instead of the traditional core of a core number of windings. Several core primary winding in series to achieve the required step-down and isolation, its internal temperature below the planar transformer, only about 10; can be installed at the rated temperature rise and so some of the PCB substrate. The third level is the updated design of successful development of thin film transformer. As a result of membrane structure, improve the achievement of low height, generally less than 1mm, frequency of more than 1MHz, up to 10MHz ~ 100MHz. Film transformer can be used integrated circuit manufacturing process, so the cost is not higher than the chip transformers, transformers film is widely used DC switching power supply transformer development.
We noted, at present, from the traditional to the development of general three-dimensional planar transformer transformer, transformer and the thin film chip transformer is only a process of development and progress, they each have their own scope of application and market position, not a type of full replacement the other category. If the current common use of electronic transformer and the output is still great; Planar Transformer Series and volume have been formed is to promote use; piece of electronic transformer is still in the small number of varieties among small-scale pilot production; film transformer is still under development research stage.
Progress together with upstream and downstream products
First, soft magnetic materials, upgrading to high-end products and the gradual development of large-scale
Development and production needs of high-end components to support high-end materials. Performance impact of electronic transformers is the main raw material magnetic. Therefore, the electronic transformer inductors are very concerned about the soft magnetic materials industry, especially its high-end materials development. In recent years, soft magnetic materials industry in China have made great progress, there are a number of large and medium enterprises to enter the soft world advanced level, middle and low soft soft magnetic material production and products in the international market accounts for an absolute advantage, high-grade Soft products have begun to form international competitiveness, can be said that the soft industry has begun to shift from the large to strong.
Upstream raw materials, product development and progress, and products for the electronics industry, the escalation of transformer provides a good foundation conditions.
