                What is the use of high frequency transformers?


High-frequency transformers are power transformers whose operating frequency exceeds mid-frequency (10kHz). They are mainly used as high-frequency switching power transformers in high-frequency switching power supplies, and also used in high-frequency inverter power supplies and high-frequency inverter welding machines for high-frequency inverters. Transform the power transformer. The main use of high-frequency transformers is also reflected in the following three points:

 

1, to improve the conversion efficiency, the use of high-frequency transformer power supply, because the work of the power supply tube in the on-off state, that is, a one-on-one non-stop switching state, so we call the "switching power supply." Less than 30% lower than traditional core transformers

 

2, can be high-frequency pulse transformer, ordinary transformer core without ferrite core magnetic permeability, can not do this

 

3, to improve the conversion efficiency, the use of high-frequency transformer power supply, because the power supply tube work in the moment of conduction - cut-off state, which is a state of non-stop switching on and off, so we call it "switching power supply." Less than 30% lower than traditional core transformers

 

High-frequency transformers are also used in electrical appliances in our daily lives, such as radios, televisions, and microwave ovens, especially switching power supplies
