A high-frequency transformer is an electronic transformer with a high operating frequency，which is generally higher than 20kHz. High-frequency transformers are mainly used in high-frequency switching power supplies as high-frequency switching power supply transformers, and are also used in high-frequency inverter power supplies and high-frequency inverter welding machines as high-frequency inverter power transformers. According to the working frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz~500kHz, 500kHz~1MHz, and above 1MHz. When the transmit power is relatively large, the IGBT is generally used as the power device, and its operating frequency is relatively low due to the tail phenomenon of the off current；If the transmit power is relatively small, MOSFET can be used, and the operating frequency is relatively high.
