PQ3230 high frequency transformer

Product Details

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