Function of the iron core

The transformer core is one of the key components of a transformer, playing the following important roles:

Magnetic circuit function: The transformer core provides a low magnetic resistance channel for magnetic flux, enabling efficient transfer of energy between the primary and secondary windings. The iron core reduces the leakage of magnetic flux by concentrating and guiding it, thereby improving the efficiency of the transformer.

Reduce losses: The material of the iron core is usually high permeability silicon steel sheets, which can greatly reduce hysteresis losses and eddy current losses. These losses will be converted into thermal energy, reducing the efficiency of the transformer. By using a thin core structure and adding silicon to the core, these losses can be effectively reduced.

Structural support: The iron core also provides structural support for the winding of the transformer, allowing the winding to be fixed in the appropriate position and avoiding displacement during operation.

Improving efficiency: By increasing the concentration of magnetic flux, the iron core can improve the electromagnetic coupling efficiency of the transformer, making the transfer of energy from the primary winding to the secondary winding more effective.

In short, the main function of the iron core is to improve the overall efficiency and performance of the transformer by concentrating magnetic flux, reducing losses, and providing support.
