Description

Technical Field

[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter welding machine. The high-frequency transformer is the most important component of a switching power supply. There are many topological structures in a switching power supply, such as a half-bridge power conversion circuit. When working, the two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, which is then transformed through a high-frequency transformer to output alternating current. The ratio of the number of turns of each winding coil of the high-frequency transformer determines the output voltage. In the production process of high-frequency transformers, a skeleton is required.
