1. High magnetic induction: saturated magnetic induction Bs = 1.2 T, is a times, permalloy ferrite of 2.5 times. Core power density is big, can reach 15 kW ~ 20 kW/kg.

2. High permeability: static initial permeability mu 0 can be as high as 120000 ~ 120000, and was equal to that of permalloy. Used in power transformer core permeability ferrite is more than 10 times, greatly reduces the excitation power, improve the efficiency of the transformer.

3. Low loss: in 20 KHZ ~ 50 KHZ frequency range is ferrite 1/2 ~ 1/5, lowering the temperature rise of the iron core.

4. High Curie temperature, Curie temperature of 570 ℃, nanocrystalline materials ferrite Curie temperature 180 ℃ ~ 180 ℃.

Due to the above advantages, made in nanocrystalline transformer used in inverter power supply, to improve power supply reliability plays a big role:

1. The low loss, low transformer temperature rise, a large number of users of long-term practical application proves that the nanocrystalline transformer temperature rise is much lower than the rise of temperature of the IGBT tubes.

2. The core permeability is high, reduces the excitation power, reduce the copper loss, improve the efficiency of the transformer. The large inductance of the transformer, reduce the impact to IGBT tubes when the current in the switch.

3. Works with magnetic induction, power density is big, can reach 15 kw/kg. Reduce the volume of core. Especially high-power inverter power supply, the volume, increase with the decrease of makes the space inside the case for IGBT tube heat dissipation.

4. The transformer overload capacity is strong, work due to the magnetic induction in about 40% of the saturated magnetic induction, when overload occurs, the only due to the increased magnetic induction heating, and will not damage the IGBT tubes by iron core saturation.

5. High Curie temperature of nanocrystalline material, assuming that the temperature is above 100 ℃, the ferrite transformer has been unable to work, nanocrystalline transformer can work normally.

Nanocrystalline these advantages, has been more and more power supply manufacturers to know and use, a number of domestic factories, has been using nanocrystalline iron core, and applied for many years. More and more manufacturers begin to use or trial. Has been widely used in inverter welding machine, communication power supply, electrolytic plating power source, induction heating power supply, rechargeable power supply, and other fields, in the next few years there will be a larger increase.
