纳米晶材料同时具备硅钢、坡莫合金和铁氧体的优点,高频逆变电源的工作频率在20kHz~50kHz,作为电源心脏的主变压器,传统的铁芯材料铁氧体虽高频损耗较低,但其100kHz以下频段的磁导率较低,且其饱和磁感应值(Bs)较低,铁芯的体积和重量仍较大,此外,铁氧体的居里温度较低,热稳定性差,温度稍高即导致Bs值降低,易饱和,工作状态不稳定,不适合于高频大功率下使用。纳米晶材料,具有优良的综合磁性能,特别是应用在高频大功率逆变电源上铁芯的首选。纳米晶铁芯不仅用于逆变焊机电源,而且广泛用于电解电镀设备、感应加热设备、充电设备、通信电源、UPS电源、X光机电源、激光电源、变频调速电源等领域。

Nanocrystalline materials have a combination advantages of silicon steel, permalloy and ferrite, the working frequency of high frequency inverter power supply is 20 kHz ~ 50 kHz, as the heart of main power supply transformer, although the traditional ferrite core material loss at high frequency is low, but the permeability of below 100 kHz frequency is relatively low, and its saturation magnetic flux density value (Bs) is also low, the volume and weight of the iron core is still large. In addition, because of low Curie temperature, weak thermal stability, Bs  value decreases quickly when little temperature rise, easy to saturation and working condition is not stable, ferrite is not suitable for high frequency power. Nanocrystalline materials have excellent comprehensive magnetic properties, especially applicable in high-power and high-frequency inverter power core. Nanocrystalline core not only used in inverter welding machine power source, but also widely used in electrolytic plating equipment, induction heating equipment, charging equipment, communication power supply, UPS power supply, X-ray source, laser power supply, frequency conversion power supply, etc.

The curie temperature of nanocrystalline material is 570℃ and that of ferrite is only 200℃. The main performance of nanocrystalline cores change less than 10% at the range from -40℃ to +140℃.
