The control system of industrial Ultrasonic welding power generator solves the problem of unexpected vibration stop of ultrasonic transducer due to rapid and violent changes of load in ultrasonic processing. It includes piezoelectric transducer, which also includes phase comparator, analog adder, voltage controlled oscillator, full bridge power amplifier, output transformer, matching circuit, voltage and current sampler, triangular wave generator, analog divider, peak detector, first low-pass filter, The second low-pass filter, voltage signal amplifier and current signal amplifier, is an improvement of the phase-locked loop frequency tracking method. By adding a narrowband forced sweep unit, the problem of excessive dependence on current signal strength in traditional phase-locked loop sweep is changed, greatly improving the reliability of frequency tracking. This utility model is suitable for use as an ultrasonic power supply.
