20khz 2000W Ultrasonic Non Woven Sewing Generator For Plastic Bag Welding Machine

The power amplifier of the ultrasonic welding power generator is a full bridge power amplifier or a half bridge power amplifier, which uses lc resonance. In this resonance mode, the frequency of the ultrasonic power source and the frequency of the ultrasonic knife handle or ultrasonic welding parts are difficult to match. In this application, the first modulator is used to provide the electric pulse after pulse width modulation, and the pulse width modulation scheme is used to enable the ultrasonic power source to work at a very wide frequency.
