一、產品介紹（Introduction）： 

隨著電源的高頻化和小型化發展趨勢，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，高頻變壓器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，目前高頻電源市場上大量采用鐵氧體磁芯變壓器，帶來的問題主要是體積大、溫升高、高溫轉換效率低、抗不均衡電流特性差、高溫輸入阻抗特性波動大和高溫漏感大，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。

With the development of high frequency and miniaturization of power supplies, design requirements are higher for the power transformer, the core component of electromagnetic conversion of high frequency power supplies. High-frequency transformers must meet the requirements of high frequency, low loss, small volume, high energy efficiency conversion efficiency and size customization.

At present, a large number of ferrite core transformers are used in the high-frequency power supply market, but their major problems are large volume, high temperature rise, low temperature conversion efficiency, poor resistance to unbalanced current characteristics, high temperature input impedance characteristics fluctuations and high temperature leakage inductance, which affect the electromagnetic compatibility of the circuit and the normal resonant working state.

In recent years, nanocrystalline have been updated iteratively. And ultra-thin ribbon has been developed vigorously to meet the development trend of high frequency which can basically meet the design requirements of high frequency transformers within 100 kHz. Nanocrystalline soft magnetic alloy materials have the advantages of high saturation magnetic induction, low loss, high power size customization design and high temperature operation reliability. It has been favored and praised by design engineers in the field of high-frequency power at home and abroad.
