Power Transformer Technology Reform Introduced and Developed
Today's power products are generally characterized by their lightness, thinness, shortness, and size. They are becoming smaller and more portable. Power transformers in power supplies, like any product that is a product, must undergo any technological innovation and must be completed under specific conditions of use. In the specific function, the pursuit of performance and price ratio is best. The electronic toroidal transformer must adapt to the volume and weight requirements of the user's power supply product. At the same time, the prices of raw materials (core materials and conductive materials) for power transformers rose. Therefore, how to reduce the volume and weight and how to reduce the cost has become the main direction for the development of power transformers in recent years. In recent years, the prices of oriented and non-oriented cold-rolled silicon steels have risen. Compared with R-type transformers, CD-type transformers and EI-type transformer cores, rolled-up annular cores can save more than 20% of core material cost due to less material consumption. , Expanded the use of the ring power transformer. The wound-type toroidal core can give full play to the properties of oriented cold-rolled silicon steel, and its working magnetic flux density is much higher than that of non-oriented cold-rolled steel. At the same time, unlike the R, CD, and EI iron cores, silicon steel materials can be fully utilized with no corner scrap and a material utilization rate of more than 98%. As a large class of power transformers for electronic transformers, cores with high magnetic core density can reduce the number of coil turns and reduce the amount of copper without reducing the core section and volume. In the present situation where the price of copper is much higher than that of iron core material, it may be a better design improvement plan. The prices of core materials and conductive materials used in electronic transformers in power supplies continue to rise, and upstream raw materials form the seller’s market. As a power supply user of downstream electronic transformers, they can select and purchase globally to form a buyer's market. In the middle of the electronic transformer industry, only take the road of technological innovation to get rid of this dilemma. However, in the mature low-frequency transformer industry, technological innovation is more difficult. However, the improvement of every small link can bring new ideas and new products.
