纳米晶薄带固化成型铁芯在中高频功率变压器上的应用

研究了FeSiBCuNb合金纳米晶铁芯固化成型方式在功率变压器上的应用，通过研究24μm和30μm不同厚度带材、固化剂等对变压器铁芯成型前后性能的影响，结果表明，24um带材可以获得更低的损耗，铁芯固化成型后损耗明显增加，导磁率变化不大，能够满足现有环形护盒铁芯在20kHz，0．5T条件下损耗小于30W／kg的要求，探索出新型的纳米晶功率变压器铁芯成型方式，为高频电源变压器的设计及后期线包的绕制提供了更多的选择方案。

Application of Nanocrystalline Ribbon Curing Molding Iron Core in High Frequency Power Transformer

The application of FeSiBCuNb nanoerystalline core curing method in power transformer and the influence on the performance of nanocrystalline power transformer core before and after molding of 24μm and 30 μm different thickness of ribbons and curing agents are studied, it shows that 24μm ribbon can obtain lower loss, iron loss in- creased significantly after curing, permeability change little and meet the demand of the loss of existing core that with circular box work at 20 kHz, 0.5 T less than 30 W/kg. Explore a new method of nanocrystalline power trans- former core forming, provides more options for the design of the high frequency power transformer and the late line winding.
