With the increasing reliance on electronic products, the market share electronic components in domestic and foreign markets gradually increased, by the demand for various types of industrial electromagnetic components are also increasing. Whether using transformers, inductors or a variety of solenoids, the need to constantly innovate high-quality magnetic components in order to ensure reliable quality and long service life of electronic and industrial systems. Among them, high-frequency transformers as a kind of electromagnetic components are slowly affecting the development of the electronics industry.

What is high frequency transformer?--My experience of high frequency transformer

At Mycoil, high-frequency transformer operating frequency exceeding IF (10kHz) power transformers, high-frequency switching power supply is mainly used for high-frequency switching power supply transformer, but also for high-frequency and high-frequency inverter power inverter welding machine for high frequency inverse variable power transformer. According to the working frequency of high and low, it can be divided into several grades: 10kHz ~ 50kHz, 50kHz ~ 100kHz,100kHz ~ 500kHz, 500kHz ~ 1MHz, 1MHz or more. Lower transmit power is relatively large, the general use of IGBT power devices, due to the presence of IGBT turn-off tail current phenomenon, so relatively low operating frequency; transmission power is relatively small, you can use MOSFET, the operating frequency is relatively high..

What are the applications of high frequency transformer?

High frequency transformer are widely used in DVD, TV, computers, speakers, radios, microwave ovens, mobile phones, automotive electronics, air conditioners, washing machines, electrical equipment, meters and other products. In my opinion, high frequency transformers affect us from everyday life to work.

What are the characteristics of high frequency transformers?

High-frequency switching power supply transformer as the most important part of the high-frequency transformer turns ratio of the individual windings of the coil determines how much the output voltage. When the work of the two transistors switch alternately conducting a high frequency pulse, blood pressure and then the AC output voltage through a low-frequency transformers, high-frequency transformer turns ratio of the individual windings of the coil determines how much the output voltage.
