15KHZ 2000W Plastic Ultrasonic Welding Machine Generator For Nylon Fabric Filter Bag Welder

15KHZ 2000W Plastic Ultrasonic Welding Machine Generator For Nylon Fabric Filter Bag Welder

The ultrasonic welding power generator adjusts the signal frequency of the preset signal to the same frequency as the resonant frequency according to the resonant frequency of the ultrasonic component in real time, and adjusts the signal frequency of the preset signal to the same frequency as the resonant frequency of the ultrasonic component when judging that the first calculated value is greater than the first preset threshold value, wherein, The first calculated value is the absolute value of the difference between the resonant frequency and the signal frequency.

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.
