From silicon steel to nanocrystalline: Evolution and application of transformer core technology

For a transformer, the static core is its main iron core, which is a closed U-shape, and the primary and secondary coils are wound on both sides of the static core; while the dynamic core is inserted in the middle of the static core.

What kind of main iron chip is in the transformer?

For a transformer, the static core is its main iron core, a closed square shape, with the primary and secondary coils wound on either side of the static core; while the dynamic core is inserted in the middle of the static core, providing a variable magnetic path in the middle of the square core. The movement of the dynamic core can adjust the output current, i.e., the welding current.
The coils on the static core form an electromagnet. The dynamic core is also part of this electromagnet circuit. When the coil is energized, the electromagnetic force causes the dynamic core to drive the contact to overcome the spring force and move, achieving the switching action. Commonly used transformer cores are generally made of silicon steel sheets because silicon steel itself is a magnetic material with strong magnetic conductivity. In an energized coil, it can generate a larger magnetic induction intensity, thus reducing the size of the transformer.
 
Toroidal cores can be processed to a gapless degree, with a stacking factor as high as 95% or more, and a core permeability of 1.5-1.8T. Therefore, the electrical conversion efficiency of toroidal transformers can reach 95% or more. The gapless structure of the toroidal transformer core allows for a very small no-load current, and there is no heat generation during long-term energization.
 
Its volume is about half that of U-type and E-type, there is no air gap, the windings are evenly wound on the toroidal core, and the magnetic circuit structure is almost in a closed space, resulting in low leakage magnetic flux, weak electromagnetic radiation, strong resistance to external magnetic interference, no need for shielding layer, and can be installed on various complex electronic devices without generating any electromagnetic interference.
