EC42 12v Mini 40W-500W Power Transformer Manufacturerhigh frequency transformer is the most important part of switching power supply. There are many topological structures in switching power supplies. For example, a half-bridge power conversion circuit. When working, two switching transistors are turned on in turn to generate a high-frequency pulse wave of 100kHz, which is then transformed through a high-frequency transformer to output alternating current. The ratio of the turns of each winding coil of the high-frequency transformer is determined How much is the output voltage. The most conspicuous of 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 above 200W, its core diameter (height) must not be less than 35mm. As for the auxiliary transformer, the core diameter of 16mm is enough when the power supply does not exceed 300W.
