Background
The high-frequency transformer is the most important component of the switching power supply. There are many topologies in switching power supplies. For example, in a half-bridge power conversion circuit, two switching transistors are conducted in turn to generate a high-frequency pulse wave of 100kHz during operation, then a high-frequency transformer transforms the voltage and outputs alternating current, and the turn ratio of each winding coil of the high-frequency transformer determines the output voltage. The most prominent of typical half-bridge transformation circuits are three high-frequency transformers: the transformer comprises a main transformer, a driving transformer and an auxiliary transformer (standby transformer), wherein each transformer has a respective standard in national regulations, for example, the diameter (height) of a magnetic core of the main transformer is not less than 35mm as long as the power supply is more than 200W.
