          一、产品介绍(Introduction):

          随着电源的高频化和大功率发展趋势欧宝体育网址,对高频电源电磁转换的核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须满足高频低损耗欧宝体育网址欧宝体育网址、小体积欧宝体育网址、高能效转换效率和尺寸可定制化的要求欧宝体育网址欧宝体育网址,目前大功率高频电源市场上大量采用硅钢等材料做变压器欧宝体育网址,带来的问题主要是损耗大、温升高欧宝体育网址欧宝体育网址、高温转换效率低等欧宝体育网址,影响了电路的电磁兼容和正常谐振工作状态欧宝体育网址欧宝体育网址;近几年纳米晶不断迭代更新欧宝体育网址欧宝体育网址欧宝体育网址欧宝体育网址,大力发展超薄带应对高频化的发展趋势,基本可以满足100kHz以内的高频变压器设计需求欧宝体育网址,纳米晶软磁合金材料具有高饱和磁感、低损耗、满足大功率尺寸定制化设计和高温运行可靠性等优点欧宝体育网址欧宝体育网址,受到了国内外高频电源领域的设计工程师的青睐和好评欧宝体育网址欧宝体育网址。纳米晶矩形和C型铁芯现已广泛应用于电动机车牵引/辅助电源、直流变流器欧宝体育网址、静电除尘电源等工业领域

          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.
