Transformer iron core

The role of the transformer core is primarily to provide a low-resistance path for the magnetic flux, thus improving the efficiency and performance of the transformer. Specifically, the core has the following key functions:

1. Magnetic Conduction: The main function of the core is to concentrate and guide the magnetic field. The alternating current (AC) in the transformer windings generates a changing magnetic field, and the core effectively transmits this magnetic field from the primary winding to the secondary winding.

2. Improving Efficiency: The core material is usually made of high magnetic permeability materials, such as silicon steel sheets, which reduce magnetic flux loss, thereby minimizing energy loss in the transformer. Without a core, the transformer would operate much less efficiently.

3. Reducing Magnetic Leakage: The core helps reduce the leakage of magnetic flux, ensuring that more magnetic flux flows through the transformer windings, which improves the transformer's efficiency and power transfer capability.

4. Reducing Size and Weight: By using a core, the transformer can transmit and concentrate magnetic flux more effectively within a smaller volume, thus reducing the size and weight of the transformer.

5. Increasing Magnetic Stability: The core helps stabilize the transformer’s magnetic field, reducing the influence of external factors on the magnetic flux, and ensuring stable operation of the transformer.

In summary, the transformer core plays a crucial role in forming the magnetic circuit, helping to transfer energy efficiently and ensuring the stable operation of the transformer.
