The Key to Power Transformation: The Transformer Core

 

In the construction of the transformer, the iron core occupies a pivotal position. The iron core is mainly made of laminated silicon steel sheets, which have high magnetic permeability characteristics and can greatly improve the magnetic conductivity. When alternating current is passed into the primary winding, an alternating magnetic field will be generated, and the iron core is like an efficient "magnetic field guide", which concentrates and guides this magnetic field to the secondary winding, allowing the secondary winding to generate an induced electromotive force based on the principle of electromagnetic induction to achieve voltage conversion.

 

 
At the same time, in order to reduce the hysteresis loss and eddy current loss generated by the iron core under the alternating magnetic field, the silicon steel sheet is designed to be very thin and the surface is insulated. Hysteresis loss comes from the energy consumption when the iron core is repeatedly magnetized, and eddy current loss is the energy loss caused by the induced current generated in the iron core. This thin and insulated silicon steel sheet laminated structure effectively reduces these losses, ensures the efficient operation of the transformer, and is the key support for the stable operation of the transformer.
