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

High frequency transformer:

1. High-frequency transformer: a power transformer whose working frequency exceeds the intermediate frequency (10kHz).

2. High-frequency transformer: Mainly used in high-frequency switching power supply as high-frequency switching power supply transformer, and also used in high-frequency inverter power supply and

It is used as a high-frequency inverter power transformer in a high-frequency inverter welding machine.

3. High-frequency transformers use high-frequency ferrite cores

Low frequency transformer:

1. Ordinary transformers are used to change voltage (current, impedance) and transfer electrical energy. It consists of a primary coil, one to several

It consists of a secondary coil and an iron core (air-core coils are commonly used at high frequencies). The same inductance, as the frequency increases, the inductive reactance gradually

Increase, so in order to adapt to the transmission of high-frequency signals, the transformer must have fewer turns to adapt to the frequency, even winding

As an air-core coil, the transmission of microwaves is sometimes wound into 3/4 or 1/2 laps.

2. Low-frequency transformer: Mainly used for low-frequency switching power supply transformers, audio transformers, home appliance speaker equipment, security monitoring equipment

Equipment, broadcasting system, solar wind energy.

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