The high-frequency transformer is a power transformer whose working frequency exceeds the intermediate frequency (10kHz). power transformer. According to the working frequency, it can be divided into several grades: 10kHz-50kHz, 50kHz-100kHz, 100kHz-500kHz, 500kHz-1MHz, and above 10MHz.

High frequency transformer is the most important part of switching power supply. There are many topologies in switching power supplies. For example, a half-bridge power conversion circuit requires two switching transistors to be turned on in turn to generate a high-frequency pulse wave of 100 kHz, which is then transformed by a high-frequency transformer to output alternating current. The turns ratio determines the output voltage. The most conspicuous in a typical half-bridge transformer circuit are three high-frequency transformers: the main transformer, the drive transformer and the auxiliary transformer (standby transformer). Each transformer has its own measurement standards in national regulations, such as the main transformer, As long as it is a power supply of more than 200W, the core diameter (height) must not be less than 35mm. As for the auxiliary transformer, when the power supply does not exceed 300W, its core diameter is 16mm.
