20khz Ultrasonic Welding Generator For Variable Frequency Manual Ultrasonic Plastic Welding Machine

20khz Ultrasonic Welding Generator For Variable Frequency Manual Ultrasonic Plastic Welding Machine

Ultrasonic power supply, including rectifier filter circuit, ultrasonic pulse drive circuit, inverter circuit, voltage limiting circuit, impedance matching circuit; The impedance matching circuit is composed of the LLC transformer and the matching capacitor. The rectification and filtering circuit is used to convert the AC power input into DC power through rectification and filtering, and is used as a power DC power source for the inverter circuit. The ultrasonic pulse driving circuit is used as the inverter circuit to provide an ultrasonic pulse driving signal. The LLC transformer includes a magnetic core, a primary wire package, and a secondary wire package. The primary wire package and the secondary wire package are connected in series on a closed magnetic circuit composed of the magnetic core. The primary wire package and the secondary wire package are isolated from each other and maintain a certain distance between them. The primary wire package is wound with a primary winding, and the secondary wire package is simultaneously wound with an isolated secondary winding and a voltage feedback winding.
