In generale, il trasformatore a bassa frequenza refers to the "power frequency transformer", which works at (50Hz) and is used to change the voltage. The iron core of the trasformatore a bassa frequenza is generally silicon steel sheet with high permeability.
Trasformatore ad alta frequenza refers to the transformer that works at high frequency and plays the role of energy conversion. Because the frequency of the magnetic field is very high, eddy currents will be generated in the silicon steel sheet (the conversion speed of small magnets in the silicon steel sheet cannot keep up), so high frequency transformers generally use "high frequency ferrite" as the magnetic core. The difference between high-frequency transformer and trasformatore a bassa frequenza lies in the difference in frequency and working frequency, which leads to some differences in material selection. The working principle of trasformatore a bassa frequenza is the same as that of high-frequency transformer. No matter the working frequency is high or low, energy is transmitted through electromagnetic induction.
Poiché le frequenze di alta frequenza e bassa frequenza sono diverse, l'alta frequenza può essere utilizzata solo nel circuito ad alta frequenza e la frequenza della sorgente di eccitazione corrisponde alla frequenza del trasformatore, mentre la bassa frequenza non può essere miscelata, anche se la frequenza dell'alta frequenza non è abbinata, non può essere utilizzata in generale.
If a transformer transmits a certain amount of energy, has a high operating frequency, transmits energy many times in a certain time, and transmits less energy each time, the transformer uses less materials and has a small structural size. Therefore, the coil turns of a general high-frequency transformer are relatively small, and the size can be very small. The coil turns of a trasformatore a bassa frequenza are relatively large.
For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the trasformatore a bassa frequenza. In this case, the high-frequency transformer will only be about one tenth of the trasformatore a bassa frequenza. This is because the trasformatore a bassa frequenza needs to be protected to reduce the U value. It is made of silicon steel sheet, but the efficiency becomes poor, so it needs to do large-scale heat dissipation.
