Discuss the difference between high frequency and low frequency transformer

About transformer, high frequency and low frequency transformer, then the high frequency and low frequency transformer in addition to the name is different and the difference? The following will talk about this problem.

In the transformer, to use the different frequency, so suitable environment is also different, since it is the high frequency transformer, is dedicated to high frequency level, of course, in low frequency range and low frequency transformer is belonged to. Despite the working frequency of high and low, about the transformer is transmission of energy by electromagnetic induction. The size of the transmit power, and the transformer used in the material, structure, size and operating frequency. If the transfer of energy to work for fixed value, high frequency, the number of transmission energy within a certain amount of time, every time transfer the energy can be less, the transformer with less material.

High frequency transformer

So that we know, the high frequency transformer and the difference is that in view of the frequency, low frequency transformer on its working frequency is different, leading to choose would have some different. Working principle of the low frequency and high frequency transformer is the same, no matter the working frequency of all is the transmission of energy by electromagnetic induction. Due to high frequency and low frequency, high frequency can only be used in high frequency and excitation frequency and frequency transformer matching circuits, and low frequency, by contrast, cannot mix, even if the frequency does not match the high frequency is usually cannot be used.

If certain transformer transmission energy, high working frequency, the number of transmission energy within a certain amount of time, every time transfer the energy can be less, the transformer with fewer materials, structure size is small, so the general of high-frequency transformer, coil number of turns is relatively small, size is very small, can do more low frequency transformer coil number of turns.

Low frequency transformer

With power under two kinds of transformer, high frequency transformer is much smaller than the low frequency transformer, in this case, the high frequency transformer is only about one over ten of the low frequency transformer. This is because the need for low frequency transformer protection, reduce the u value, made of silicon steel sheet, but the efficiency is poor, so to do big volume heat dissipation.
