Regarding transformers, there are high-frequency transformers and low-frequency transformers. What are the differences between high-frequency transformers and low-frequency transformers besides the difference in name? Let's talk about this issue below.

Among the transformers, there are differences in frequency usage, so the applicable environment is also different. Since it is a high-frequency transformer, it is of course dedicated to the high-frequency level, and the low-frequency transformer is also exclusive in the low-frequency range. Regardless of the operating frequency, the transformer transmits energy through electromagnetic induction. The size of the transmitted energy is related to the material, structure, size and operating frequency of the transformer. If the transmitted energy is a fixed value, the working frequency is high, and the number of energy transmissions within a certain period of time is large, and the energy transmitted each time can be less, the transformer uses less material.

High frequency transformer

In this way, we know that the difference between high-frequency transformers and low-frequency transformers lies in their different working frequencies in terms of frequency, which leads to some differences in selection. The working principle of low frequency transformer and high frequency transformer is the same. Regardless of the working frequency, energy is transmitted through electromagnetic induction. Due to the different frequencies of high frequency and low frequency, high frequency can only be used in circuits where the frequency is high and the excitation source frequency matches the frequency of the transformer, while low frequency is the opposite and cannot be mixed, even if high frequency does not match the frequency Is not available.

If the transformer transmits a certain amount of energy, the working frequency is high, and the number of energy transmissions within a certain period of time is large, and the energy transmitted each time can be less, the transformer uses less materials and the structure size is small. Therefore, the general high-frequency transformer has the number of coil turns. It is relatively small, the size can be made very small, and the number of turns of the low-frequency transformer is relatively large.

Low frequency transformer

For the two transformers at the same power, the high-frequency transformer is much smaller than the low-frequency transformer. In this case, the high-frequency transformer is only 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 becomes poor, so a large-volume heat dissipation is required.
