The working principle of the ultrasonic plastic welding power generator mainly utilizes the oscillation and amplification effects of electronic circuits to convert the input AC energy into high-frequency energy. Specifically, power generators typically consist of oscillators, power amplifiers, output matching networks, and other components. The oscillator is responsible for generating high-frequency oscillation signals, while the power amplifier amplifies this signal to provide sufficient energy to the ultrasonic transducer. The output matching network is used to ensure impedance matching between the power generator and the ultrasonic transducer, in order to achieve maximum energy transfer efficiency.
