Talking about the difference between high frequency transformer and low frequency transformer

Regarding the transformer, there are high-frequency transformers and low-frequency transformers. What are the differences between the high-frequency transformers and the low-frequency transformers besides the names? Let's talk about the difference between the High frequency transformer and the low frequency transformer.

In the transformer, there is a difference in the use of frequency, so the applicable environment is also different. Since it is a high-frequency transformer, it is of course dedicated to the high-frequency layer, and the low-frequency transformer is also exclusive in the low-frequency range. Aside from the operating frequency, the transformers transmit energy through electromagnetic induction. The amount of energy transferred is related to the material, structure, size and operating frequency of the transformer. If the transmitted energy is constant, the operating frequency is high, and the number of times of energy transmission is large within a certain period of time, and the energy per transmission can be small, and the material for the transformer is small.

In this way, we know that the difference between a high-frequency transformer and a low-frequency transformer lies in the difference in the operating frequency for the frequency, which leads to some differences in the selection. The low-frequency transformer works in the same way as the high-frequency transformer. It transmits energy through electromagnetic induction regardless of the operating frequency. Due to the different frequencies of high frequency and low frequency, high frequency can only be used in circuits with high frequency and excitation source frequency matching with transformer frequency, while low frequency is opposite, can not be mixed, even if the high frequency does not match the frequency. Can not be used.

If the transformer transmits a certain amount of energy, the working frequency is high, and the number of times of transmitting energy in a certain period of time is large, and the energy per transmission can be small, the material for the transformer is small, and the structure size is small, so the general high-frequency transformer, the number of turns of the coil Less, the size can be made very small, and the number of low-frequency transformer coils is relatively large.

In the case of two kinds of transformers under the same power, the high-frequency transformer will be much smaller than the low-frequency transformer. In this case, the high-frequency transformer will only have about one-tenth of the low-frequency transformer. This is because the low-frequency transformer needs to be protected, the u value is reduced, and the silicon steel sheet is used, but the efficiency is deteriorated, so that a large volume of heat is to be dissipated.
