Nanocrystalline Switch HI-Power Transformer Core Iron-based

Usually the Hi-power arc welding inverter' s single-ended pulse

transformers require the transformer cores with lowhigh frequency

loss, high Bs and lowBr so that to achieve bigger AB. Output filter

and energy stored inductance required the characteristics of high Bs,

lowloss and constant permeabilityin this case, we made horizontal

magnetic treatmenton Nano-crystalline alloy to manufacture the

transformer cores with lowBr and constant permeability.

Application

l Inverter Welding machine power supply

l X-ray, laser, communication power supply

l UPS and high frequency induction heating power supply 

l Charging power supply

l Electro lytic and electroplate power supply

l Frequency control of motor speed powersupply

l Plasma cutting machine

Characteristics

l High Bs - Reducing volume and weight of the cores

l High permeability and low Coercive force - Higher efficiency and less

l excited power of transformer

l LowBr ( Br < 0.2T - Higher magnetic flux density and output power 

l Low core loss - Lower temperature rising, higher efficiency of the

l transformer

l Keep stable working at -45°C-130°C  for long time.
