一、產品介紹(Introduction):

隨著電源的高頻化和大功率發展趨勢,對高頻電源電磁轉換的核心部件功率變壓器也提出了更高的設計要求,大功率高頻變壓器鐵芯必須滿足高頻低損耗、小體積、高能效轉換效率和尺寸可定制化的要求,目前大功率高頻電源市場上大量采用硅鋼等材料做變壓器,帶來的問題主要是損耗大、溫升高、高溫轉換效率低等,影響了電路的電磁兼容和正常諧振工作狀態;近幾年納米晶不斷迭代更新,大力發展超薄帶應對高頻化的發展趨勢,基本可以滿足100kHz以內的高頻變壓器設計需求,納米晶軟磁合金材料具有高飽和磁感、低損耗、滿足大功率尺寸定制化設計和高溫運行可靠性等優點,受到了國內外高頻電源領域的設計工程師的青睞和好評。納米晶矩形和C型鐵芯現已廣泛應用于電動機車牽引/輔助電源、直流變流器、靜電除塵電源等工業領域

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.  


二、產品特點(Characteristic):

—低損耗 Low Core Loss

納米晶C型鐵芯與其他磁性金屬材料制成的鐵芯相比具有更低的損耗。

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