A constant amplitude control circuit for ultrasonic power supply, including a transducer, PFC component, inverter component, high-frequency resonance component, and also including a sampling circuit, voltage amplification circuit, high-speed zero crossing detection circuit, high-speed electronic switch, voltage error comparator. The sampling circuit is set at both ends of the transducer, and the sampling circuit extracts high-frequency and low-voltage signals and transmits them to the voltage amplification circuit and 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, and the output end of the high-speed electronic switch is connected to the voltage error comparator. The voltage error comparator is connected to the PFC component to achieve high-speed regulation of the transducer power supply PFC circuit. The design of this utility model monitors the voltage value of each single cycle of high-frequency sine waves at both ends of the transducer through a circuit, and achieves high-speed adjustment of the PFC circuit powered by the transducer through a high-speed electronic switch; And avoid the impact of old-fashioned output power regulation on amplitude when changing the current size.
