Switch Hi-power Transformer Core

Short Description:

Usually the Hi-Power arc welding inverter’s single-ended pulse transformers require the transformer cores with low high frequency loss, high Bs and low Br so that to achieve bigger B. Output filter and energy stored inductance 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.

Appications

● Inverter Welding machine power supply
● X-ray, laser, communication power supply
● UPS and high frequency induction heating power supply
● Frequency control of motor speed power supply
● Charging power supply
● UPS

Performance

● High Bs - Reducing volume and weight of the cores
● High permeability and low Coercive force --Higher efficiency and less excited power of transformer
● Low Br (Br≤0.2T) - Higher magnetic flux density and output power
● Low core loss - Lower temperature rising,higher efficiency of the transformer
● Keep stable working at -45℃ ~ 130 ℃ for long time.
