High frequency transformer

Short Description:

High-frequency transformers are mainly used as high-frequency switching power supply transformers in high-frequency switching power supplies, and are also used as high-frequency inverter power supply transformers in high-frequency inverter power supplies and high-frequency inverter welding machines. According to the working frequency, it can be divided into several frequency ranges: 10kHz-50kHz, 50kHz-100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 1MHz. In the case of relatively large transmission power, power devices generally use IGBTs. Due to the tailing phenomenon of the turn-off current of the IGBT, the operating frequency is relatively low; if the transmission power is relatively small, MOSFETs can be used, and the operating frequency is relatively high.

Overview:

Transformers are coupled by magnetic flux linkage, or mutual inductance.

(1) In order to reduce loss, high-frequency transformers often use soft magnetic materials with high permeability and low high-frequency loss as cores.

(2) High-frequency transformers are generally used in small-signal applications, with relatively small size and fewer coil turns.

Mainly used in high frequency switching power supply as high frequency switching power transformer, also used in high frequency inverter power supply and high frequency welding machine as high frequency inverter transformer.
