Why do not low-frequency transformers use ferrite cores?
The low frequency transformer is used to transmit the signal voltage and signal power, and also to realize the impedance matching between the circuits, and has the isolation function to the direct current.
Saturation magnetization is not enough. Ferrite 4000Gs, silicon steel sheet, 14000Gs.The same volume of transformers, ferrite cores, power capacity is much lower.
High frequency transformer and low frequency transformer on the principle of no difference. But due to the high frequency and low frequency. The frequency of different iron core transformer used. Low frequency transformers for general silicon steel sheet with high permeability. The high frequency transformer with high frequency ferrite cores.
