En général, le transformateur basse fréquence refers to the "power frequency transformer", which works at (50Hz) and is used to change the voltage. The iron core of the transformateur basse fréquence is generally silicon steel sheet with high permeability.
Transformateur haute fréquence 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 transformateur basse fréquence lies in the difference in frequency and working frequency, which leads to some differences in material selection. The working principle of transformateur basse fréquence is the same as that of high-frequency transformer. No matter the working frequency is high or low, energy is transmitted through electromagnetic induction.
Étant donné que les fréquences de haute fréquence et de basse fréquence sont différentes, la haute fréquence ne peut être utilisée que dans le circuit à haute fréquence et la fréquence de la source d'excitation correspond à la fréquence du transformateur, tandis que la basse fréquence ne peut pas être mélangée, même si la fréquence de haute fréquence n'est pas adaptée, elle ne peut pas être utilisée généralement.
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 transformateur basse fréquence are relatively large.
For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the transformateur basse fréquence. In this case, the high-frequency transformer will only be about one tenth of the transformateur basse fréquence. This is because the transformateur basse fréquence 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.
