Low-power high-frequency transformer core products and characteristics content sharing

Nanocrystalline materials have the advantages of silicon steel, permalloy and ferrite at the same time. The operating frequency of high-frequency inverter power is 20kHz~50kHz. As the main transformer of the heart of the power supply, although the traditional iron core material ferrite Low, but its magnetic permeability in the frequency band below 100kHz is low, and its saturation magnetic induction value (Bs) is low, the volume and weight of the iron core are still large, in addition, the Curie temperature of ferrite is low, and the thermal stability is poor , a slightly higher temperature will lead to lower Bs value, easy saturation, unstable working state, not suitable for use under high frequency and high power. Nanocrystalline materials have excellent comprehensive magnetic properties, especially the best choice for iron cores used in high-frequency and high-power inverter power supplies. Nanocrystalline iron core is not only used in inverter welding machine power supply, but also widely used in electrolytic plating equipment, induction heating equipment, charging equipment, communication power supply, UPS power supply, X-ray machine power supply, laser power supply, frequency conversion speed regulation power supply and other fields.

Features

High saturation magnetic induction - effectively reduce the size of the transformer

High magnetic permeability and low coercive force - improve transformer efficiency, reduce excitation power, and reduce copper loss

Low loss - reduce the temperature rise of the transformer

Excellent temperature stability - can work for a long time at -55~130°C
