The feedback frequency of the control system of the industrial Ultrasonic welding power generator is compared in the comparison link stored in the controller chip, and the deviation frequency ratio is generated; The deviation PWM pulse width duty cycle is converted into a PWM pulse width duty cycle through a conversion processing stage; In the amplification stage, the PWM pulse width duty cycle controls the transducer driving voltage of the stage; The energy conversion driving voltage is matched and resonated through the energy conversion execution link to generate the energy conversion driving current; After calculating and processing the frequency conversion feedback loop, the transducer driving voltage and transducer driving current are converted into ultrasonic processing feedback frequency and introduced into the comparison loop
