一般に、 低周波トランス refers to the "power frequency transformer", which works at (50Hz) and is used to change the voltage. The iron core of the 低周波トランス is generally silicon steel sheet with high permeability.
高周波トランス 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 低周波トランス lies in the difference in frequency and working frequency, which leads to some differences in material selection. The working principle of 低周波トランス is the same as that of high-frequency transformer. No matter the working frequency is high or low, energy is transmitted through electromagnetic induction.
高周波と低周波の周波数が異なるため、高周波は高周波の回路でのみ使用でき、励磁源の周波数はトランスの周波数と一致しますが、低周波は混合できません。高周波の周波数が合わず、一般的には使えません。
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 低周波トランス are relatively large.
For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the 低周波トランス. In this case, the high-frequency transformer will only be about one tenth of the 低周波トランス. This is because the 低周波トランス 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.
