The difference between high frequency transformer and low frequency transformer?
In general, transformer transformer refers to "power frequency transformer", which works at (50 Hz) to change voltage and replace transformer core, which is generally silicon steel sheet with high permeability.
High frequency transformer is a kind of transformer which works at high frequency and acts as transducer. Due to the high frequency of magnetic field, eddy current will be generated in silicon steel plate (the conversion speed of silicon steel plate can not keep up with it), so high frequency transformer generally uses "high frequency ferrite" as magnetic core.
The difference between high frequency transformer and transformer transformer is that the frequency of working frequency is different, which leads to some differences in material selection. The working principle of transformer and high frequency transformer is the same. The working frequency is high and low, and the energy is transmitted through electromagnetic induction.
Because of the difference between high frequency and high frequency, high frequency can only be used in the circuit where the frequency of high frequency and excitation source matches the frequency of transformer, but the reverse can not be mixed. If the high frequency does not match the frequency, it is usually not available.
If the transformer transmits a certain amount of energy, the working frequency is high, and the number of times of energy transmission at a specific time is large, and the energy transmitted each time may be very small, and the material of the transformer is also very small. Because of the small structure size, the turn number of ordinary high-frequency transformer and coil is compared. Less, can make the size very small, and the number of transformer coils is relatively large.
The transformer has much less power penetration than the transformer at high frequency. In this case, the high frequency transformer will have only one or more transformers. This is because of the need to protect the transformer, reduce the U value, and made of silicon steel plate, but the efficiency is reduced, so the need for large volume of heat dissipation.
