In a transformer, the primary function of the inductor is to store and transfer energy between the primary and secondary coils. The inductor helps to create a magnetic field when an alternating current flows through the primary coil, which induces a voltage in the secondary coil. This voltage is then used to power electrical devices or systems connected to the secondary coil.

Functions of an Inductor in a Transformer:
1. Energy Storage:
- Inductors store inductive energy when current flows through them.
- In a transformer, the inductors on the primary and secondary windings act as energy reservoirs.
2. Impedance Control:
- Inductors offer inductive impedance, which limits the flow of alternating current (AC).
- By varying the inductance of the windings, the transformer's impedance can be controlled to optimize energy transfer.
3. Voltage Regulation:
- Inductance on the primary winding of the transformer helps regulate the voltage on the secondary winding.
- By increasing or decreasing the inductance, the voltage ratio between the windings can be adjusted to maintain a desired output voltage.
4. Transient Suppression:
- Inductors in the windings and external to the transformer help suppress transient voltage spikes and surges.
- They absorb excess energy during switching transients, reducing the risk of damage to the transformer and other connected devices.
5. Isolation:
- Inductors can provide isolation between the primary and secondary windings of the transformer.
- The inductive impedance between the windings prevents direct current (DC) from flowing, ensuring safe isolation.
6. Current Limiting:
- High inductance in the transformer's windings can limit the flow of short-circuit current.
- This helps protect the transformer and connected circuits from excessive currents.
7. Reactance Balance:
- Inductors in the secondary winding help balance the reactance between the windings.
- This ensures proper voltage distribution and reduces voltage distortion at the output.
