15KHZ/20KHZ Ultrasonic welding generator power supply uses a pid controller to calculate the step size of frequency change, mainly based on the fact that the resonance frequency of the ultrasonic system will increase to a certain extent as the ultrasonic generator changes with the load resistance. Therefore, the ultrasonic system has the largest working current when working at the resonance frequency. Therefore, the step size parameters can be adjusted according to the peak change relationship between the current and the frequency change.
