15KHZ/20KHZ Ultrasonic welding generator power supply can realize the frequency tracking function of the ultrasonic generator, so that the ultrasonic generator can follow the change of the equivalent capacitance and resistance of the ultrasonic generator load with the work, which will lead to the drift of the natural frequency of the ultrasonic acoustic system; The variable step frequency sweep controlled by a pid controller can quickly adjust the output frequency of the ultrasonic generator, enabling the entire ultrasonic system to quickly adjust to the resonant state and output maximum power. This variable step frequency sweep tracking control method reflects the advantages of fast real-time speed, simple electrical circuit, and easy cost implementation.
