Power frequency transformers are also generally called low frequency transformers. What is the difference between the working frequency of it and the highfrequency transformer?

The working frequency of the power frequency transformer is generally between 50HZ60HZ.
The working frequency of highfrequency transformers is generally above 1000HZ or even tens or hundreds of KHZ.

The scope of application of the two is therefore different.

Power frequency transformers are generally used on 110V~240V AC and 50/60HZ to convert high voltage to low voltage, such as range hoods, speakers, power supply equipment, etc., with a wide range of applications.

The application range of highfrequency transformers is even wider, such as: mobile phone chargers, lighting, switching power supplies, household appliances, computer power supplies, drives, medical equipment, military industry, etc.

Because of the low energy efficiency conversion of power frequency transformers, in many cases, the power frequency transformers that were originally required have been replaced by high frequency transformers.

There are more winding turns on the power frequency transformer, compared with the high frequency transformer.

Therefore, the conversion efficiency of high frequency transformers is much higher than that of power frequency transformers.

Under the same volume, the power of the highfrequency transformer is definitely greater than that of the industrial frequency transformer.

The advantage of power frequency transformer is durability.

The difference between high frequency transformer and power frequency transformer used in the circuit:

1.In the circuit, the highfrequency transformer cannot be used directly and must be matched with the drive circuit.

2. The power frequency transformer can be used directly in the 220V circuit. After the 220V voltage is connected, the power frequency transformer can help output the required voltage, and then complete the filtered output through the ballast.
