1. Details:
Usually the Hi-power arc welding inverter's single-ended pulse transformers require the transformer cores with low high frcqucncy loss, high Bs and low Br so that to achicvc bigger A B. Output filter and energy stored inductancc required the characteristics of high Bs, low loss and constant permeability, in this case, we made horizontal magnetic treatment on Nano-crystalline alloy to manufacture the transformer cores with low Br and constant permeability.
Application:
• Inverter Welding machine power supply
• X-ray, laser, communication power supply
• UPS and high frequency induction heating power supply
• Charging power supply
• Electrolytic and electroplate power supply
• Frcqucncy control of motor speed power supply
Product performance:
• High Bs —Reducing volume and weight of the cores
• High permeability and low Coercive force
• Low Br (Br < 0.2T) ---Higher magnetic flux density and output power
• Low core loss —Lower temperature rising, higher efficiency of the transformer
• Excellent temperature stability —Keep stable working at -50'C-130'C for long time
