What are the differences between high frequency transformers and low frequency transformers?

High frequency transformer:

1、 high-frequency transformer: the working frequency exceeds the intermediate frequency (10kHz) of the power transformer.

2、high-frequency transformer: mainly used in high-frequency switching power supply as high-frequency switching power transformer, but also for high-frequency inverter power supply and high frequency inverter welding machine for high frequency inverter power transformer.

3、 High-frequency transformer uses high-frequency ferrite core

Low frequency transformer:

1、the ordinary transformer is used to change the voltage (current, impedance), is to transfer electrical energy, it consists of a primary coil, a to a few

A secondary coil and an iron core (high frequency, commonly used hollow coil). The same inductance is gradually reactance as the frequency increases Increase, so in order to adapt to the transmission of high-frequency signals, the transformer must adapt to the frequency with fewer turns, or even around Into a hollow coil, microwave transmission is wound into 3/4 or 1/2 turns, etc.

2、 low-frequency transformer: mainly used in low-frequency switching power transformer, audio transformer, home appliance speaker equipment, security monitoring equipment, broadcasting system, solar and wind energy.

3、Low frequency transformers generally use silicon steel sheets with high permeability.
