The 1200W 15khz/20khz Ultrasonic welding power generator provides an ultrasonic power constant amplitude control circuit, including a transducer, a pfc module, an inverter module, and a high-frequency resonant module. The two ends of the transducer are respectively connected to the high-frequency resonant module. The high-frequency and high-voltage signals provided by the pfc module are successively transmitted to the transducer through the inverter, the high-frequency resonant module, and are characterized in that they also include a sampling circuit A voltage amplification circuit, a high-speed zero crossing detection circuit, a high-speed electronic switch, and a voltage error comparator are arranged at both ends of the transducer. The sampling circuit extracts high-frequency and low-voltage signals and transmits them to the voltage amplification circuit and the high-speed zero crossing detection circuit. The output signals from the voltage amplification circuit and the high-speed zero crossing detection circuit are simultaneously connected to the high-speed electronic switch, The output end of the high-speed electronic switch is connected to the voltage error comparator, and the voltage error comparator is connected with the pfc module to realize high-speed regulation of the power supply pfc circuit of the Ultrasonic welding transducer.
