En general, el transformador de baja frecuencia refers to the "power frequency transformer", which works at (50Hz) and is used to change the voltage. The iron core of the transformador de baja frecuencia is generally silicon steel sheet with high permeability.
Transformador de alta frecuencia 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 transformador de baja frecuencia lies in the difference in frequency and working frequency, which leads to some differences in material selection. The working principle of transformador de baja frecuencia is the same as that of high-frequency transformer. No matter the working frequency is high or low, energy is transmitted through electromagnetic induction.
Dado que las frecuencias de alta y baja frecuencia son diferentes, la alta frecuencia solo se puede usar en el circuito con alta frecuencia y la frecuencia de la fuente de excitación coincide con la frecuencia del transformador, mientras que la baja frecuencia no se puede mezclar, incluso si la frecuencia de alta frecuencia no coincide, no se puede usar en general.
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 transformador de baja frecuencia are relatively large.
For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the transformador de baja frecuencia. In this case, the high-frequency transformer will only be about one tenth of the transformador de baja frecuencia. This is because the transformador de baja frecuencia 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.
