High frequency transformer is a kind of transformer, as the main component of switching power supply. There are many topologies in switching power supplies. For example, in the half-bridge power conversion circuit, two switching audides turn on to generate 100kHz high-frequency pulse wave when working, and then perform voltage change through the high-frequency transformer to output alternating current. The proportion of turns of each winding coil of the high-frequency transformer determines the output voltage. Typical half-bridge transformer circuit is the most prominent three high-frequency transformers: main transformer, driving transformer and auxiliary transformer (standby transformer), each transformer in the national regulations have their own measurement standards, such as the main transformer, as long as it is more than 200W power, its magnetic core diameter (height) shall not be less than 35mm. The auxiliary transformer, when the power supply does not exceed 300W, its magnetic core diameter is enough to reach 16mm.
