纳米晶资料同时具有硅钢、坡莫合金和铁氧体的长处,高频逆变电源的任务频率在20kHz~50kHz,作为电源心脏的主变压器,传统的铁芯资料铁氧体虽高频消耗较低,但其100kHz以下频段的磁导率较低,且其饱和磁感到值(Bs)较低,铁芯的体积和分量仍较大,别的,铁氧体的居里温度较低,热波动性差,温度稍高即招致Bs值低落,易饱和,任务形态不波动,不合适于高频大功率下运用。纳米晶资料,具有优秀的综合磁功能,特殊是使用在高频大功率逆变电源上铁芯的首选。纳米晶铁芯不只用于逆变焊机电源,并且普遍用于电解电镀设置装备摆设、感到加热设置装备摆设、充电设置装备摆设、通讯电源、UPS电源、X光机电源、激光电源、变频调速电源等范畴。

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.

纳米晶居里温度570℃,传统铁氧体的居里温度仅200℃,在-40℃~+140℃温度范畴内,纳米晶铁芯次要磁特性变革率小于10%,而传统的铁氧体却高达50%以上,用纳米晶铁芯制造的滤波器件,可以更好地使用于低温情况,更顺应情况变革。

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℃. But the changing rate of ferrite is more than 50%. Filters made of nanocrystalline cores can be better applied to high-temperature environment and adapt to environment change.
