Quick Details
Specifications
Power inverter welding power single-ended pulse transformer requires its core a low high frequency loss, a high saturation flux density Bs, low residual magnetic induction Br to reach a biggest work magnetic
induction △B; output filtering and stored induction requires a high saturation flux density, low loss and
constant magnetic properties, therefore transverse magnetic heat treatment process is needed to reach
that properties.
Applications :
▲ Power supply of inverter welding machine
▲ Power supply of X-ray, laser and communication device
▲ UPS and high frequency induction heating power supply
▲ Charging power supply
▲ Electroplating Power supply
▲ Frequency modulation speed electrical power
Properties :
▲ High saturation flux density---an effective reducing component' s sizes
▲ High magnetic permeability and low coercivity---result in improving transformer efficiency, reducing exciting power
▲ High magnetic permeability and low coercivity---result in improving transformer efficiency, reducing exciting power
▲ Low remanence(Br≤ 0.2T)--result in bigger induction increasing and bigger output power
▲ Low loss---result in lowing the temperature rising of transformer
▲ Good temperature stability---workable for long under temperature up to 130° C
▲ Low loss---result in lowing the temperature rising of transformer
▲ Good temperature stability---workable for long under temperature up to 130° C
Performance :
▲ Performance compared with ferrite core
