Increase in Flux Density in Core of a Transformer
When the flux density in the core of a transformer is increased, it has some effects on the transformer's performance. Let us discuss these effects in detail below.
Size of Transformer Can be Reduced
When the flux density is increased, it means that the same amount of magnetic flux can be achieved with a smaller cross-sectional area of the core. Therefore, the size of the transformer can be reduced.
Reduction in Eddy Current Losses
Eddy currents are produced in the core of the transformer due to the magnetic field changes in the core. These currents cause power losses in the form of heat. When the flux density is increased, it means that the same amount of magnetic flux can be achieved with a smaller cross-sectional area of the core. Therefore, the eddy current losses are reduced.
No Effect on Frequency or Wave Shape
The frequency on the secondary winding and the wave shape on the secondary side are not affected by the increase in flux density in the core of the transformer. These parameters depend on the input voltage frequency and the load connected to the secondary winding.
Conclusion
From the above discussion, we can conclude that when the flux density in the core of a transformer is increased, the size of the transformer can be reduced, and eddy current losses are reduced. However, it has no effect on the frequency or wave shape on the secondary side.
