一、产品引见(Introduction):

随着电源的高频化和大功率开展趋向,对高频电源电磁转换的中心部件功率变压器也提出了更高的设计要求,大功率高频变压器铁芯必需满意高频低消耗、小体积、高能效转换服从和尺寸可定制化的要求,现在大功率高频电源市场上少量接纳硅钢等资料做变压器,带来的题目次要是消耗大、温降低、低温转换服从高等,影响了电路的电磁兼容和正常谐振任务形态;近几年纳米晶不时迭代更新,鼎力开展超薄带应对高频化的开展趋向,根本可以满意100kHz以内的高频变压器设计需求,纳米晶软磁合金资料具有高饱和磁感、低消耗、满意大功率尺寸定制化设计和低温运转牢靠性等长处,遭到了国际外高频电源范畴的设计工程师的喜爱和洽评。纳米晶矩形和C型铁芯现已普遍使用于电动机车牵引/辅佐电源、直流变流器、静电除尘电源等产业范畴

With the high frequency and power development trend of the power supply, the core components of the high frequency power supply put forward higher design requirements. The high-power transformer core must meet the demand of high frequency, low loss, small volume, high energy conversion efficiency, and the core size should be customized. At present, a large number of materials such as silicon steel are used as transformers in the high-power high-frequency power supply market. The problems are mainly caused by large loss, high temperature rise, low temperature conversion efficiency, etc. In recent years, nanocrystalline ribbon products have been iteratively updated, and the development trend of ultra-thin ribbons to cope with high-frequency development has been vigorously developed, which can basically meet the design requirements of high-frequency transformers within 100 kHz. Nanocrystalline soft magnetic alloy materials have high saturation magnetic induction, low loss, high power size customization design and high temperature operation reliability. Nanocrystalline rectangular and C-typed cores are now widely used in industrial fields such as traction/auxiliary power supplies for electric vehicles, DC converters, and electrostatic precipitators.  


二、产品特点(Characteristic):

—低消耗 Low Core Loss

纳米晶C型铁芯与其他磁性金属资料制成的铁芯相比具有更低的消耗。

Nanocrystalline C-Cores have much lower core loss than those made of other magnetic metallic materials.
