В целом, низкочастотный трансформатор refers to the "power frequency transformer", which works at (50Hz) and is used to change the voltage. The iron core of the низкочастотный трансформатор is generally silicon steel sheet with high permeability.
Трансформатор высокой частоты 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 низкочастотный трансформатор lies in the difference in frequency and working frequency, which leads to some differences in material selection. The working principle of низкочастотный трансформатор is the same as that of high-frequency transformer. No matter the working frequency is high or low, energy is transmitted through electromagnetic induction.
Поскольку частоты высокой частоты и низкой частоты различны, высокая частота может использоваться только в цепи с высокой частотой, а частота источника возбуждения совпадает с частотой трансформатора, при этом низкая частота не может смешиваться, даже если частота высокой частоты не соответствует, ее нельзя использовать вообще.
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 низкочастотный трансформатор are relatively large.
For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the низкочастотный трансформатор. In this case, the high-frequency transformer will only be about one tenth of the низкочастотный трансформатор. This is because the низкочастотный трансформатор 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.
