Nanocrystalline Core Products And Characteristics Of Low Power And High Frequency Transformer


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