Amorphous and nanocrystalline have high magnetic permeability and saturation magnetic flux density, and have good soft magnetic properties within a certain frequency range. Due to its excellent characteristics, amorphous and nanocrystalline soft magnetic materials in different applications, make up for the shortage of silicon steel and ferrite materials, make all kinds of electronic products to a new level, improve the efficiency, and achieve obvious energy-saving effect. The new material shows the vigor and vitality.

Here we take 20kHz ~ 50kHz high frequency transformer as an example:

The original HF transformers generally using ferrite transformer core, core form is mostly U-type or EI type, a few use O-type core, U-type or EI type iron core from the structure is difficult to reduce the leakage inductance of transformers. Because of the advantages of nanocrystalline magnetic ring (ultramicrystalline iron core), it provides an ideal material for the miniaturization and high efficiency of high frequency transformer. Because it can make full use of the nanocrystalline copper (ultrafine grain core) with high magnetic permeability and high magnetic induction intensity of the transformer, low loss, magnetic characteristics of the circular iron core, small magnetic leakage, innovative in the primary and secondary structure of the transformer Features. The metal protection box of the iron core is used as the secondary coil of the transformer, which is suitable for high current output. The primary coil is evenly wound on the secondary, and the leakage inductance is very small. The transformer fixing bracket is integrated with the bus output, which is conducive to heat dissipation.

The advantages of this transformer are:

1. Large power: 10 kW ~ 20kW, power density can reach 15 kW ~ 20kW/kg

2. Small leakage inductance, the general level is less than 5μh, the best is less than 2μh

3. High efficiency, reaching more than 99%

4. Small size, light weight, 15 kW transformer weight of 3 kg, volume of 160×150×95 mm

In view of the excellent characteristics of amorphous nanocrystalline soft magnetic materials, our company uses amorphous nanocrystalline materials in actual production for high-power medium and high frequency transformers, high-frequency switching power supplies, high-precision current transformers, and magnetic sensors in electronic equipment and other devices.
