Effect of Increase in Supply Frequency on Iron Loss in Transformer
Introduction:
Iron loss is a type of power loss that occurs in transformer core due to the flow of alternating magnetic flux. It is also known as core loss or hysteresis loss. The iron loss is dependent on the frequency of the supply voltage, which affects the magnetic properties of the core material.
Effect of Increase in Supply Frequency on Iron Loss:
When the supply frequency to the transformer is increased, the magnetic flux density in the core material also increases. This is because the magnetic flux is proportional to the frequency of the supply voltage. As a result, the iron loss in the transformer core increases due to the following reasons:
Conclusion:
In summary, the iron loss in the transformer core increases when the supply frequency is increased. This is because the magnetic flux density in the core material also increases, leading to more energy dissipation in the form of hysteresis loss and eddy current loss. Therefore, it is essential to consider the frequency of the supply voltage when designing a transformer to ensure optimal performance and efficiency.

When the supply frequency to the transformer is increased, the magnetic flux density in the core material also increases. This is because the magnetic flux is proportional to the frequency of the supply voltage. As a result, the iron loss in the transformer core increases due to the following reasons:
- Hysteresis Loss: Hysteresis loss is one of the major components of iron loss. It is caused by the continuous reversal of magnetization in the core material due to the alternating magnetic field. When the supply frequency is increased, the magnetization process becomes faster, and more energy is dissipated in the form of hysteresis loss.
- Eddy Current Loss: Eddy current loss is another component of iron loss that occurs due to the circulation of eddy currents in the core material. The magnitude of eddy current loss is proportional to the square of the supply frequency. Therefore, when the supply frequency is increased, the eddy current loss also increases.
Conclusion:
In summary, the iron loss in the transformer core increases when the supply frequency is increased. This is because the magnetic flux density in the core material also increases, leading to more energy dissipation in the form of hysteresis loss and eddy current loss. Therefore, it is essential to consider the frequency of the supply voltage when designing a transformer to ensure optimal performance and efficiency.
