Hi-power transformer core

Product Profile :

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.

► Advantages  ( Hi-power transformer core ) :


      ● High saturation magnetic flux density - effectively reduce the volume of the device, reduce the quality of the device

      ● High permeability low coercivity - improved efficiency of the transformer, reducing the exciting power

      ● Low remanence (Br≤0.2T) - magnetic induction greater increment, greater transmission power

      ● Low-loss - reduce the temperature rise of the transformer, the transformer improve efficiency

      ● Excellent temperature stability - long-term work at temperatures up to -45 ℃ ~ 130 ℃
