The control power generator of ultrasonic cleaning machine is a sweeping frequency ultrasonic cleaning power source in the field of ultrasonic technology. Due to the dual effects of physical and chemical cleaning, ultrasonic cleaning has a wide range of applications. The main circuit is composed of rectifier, filter, half-bridge inverter circuit, transformer, and resonant circuit. The control circuit generates a sweeping control signal with a certain bandwidth to drive the power transistor in the main circuit. The control circuit is composed of integrated circuits, power transistors, pulse transformers, operational amplifiers, voltage comparators, etc.
The control power generator of the ultrasonic cleaning machine selects an ultrasonic power source with a certain bandwidth to drive the ultrasonic transducer to ensure that the average emission power of each transducer is basically the same, reduce the influence of changes in physical parameters on ultrasonic emission power, and finally make the cleaning effect of the cleaned workpieces consistent, and eliminate the manual frequency modulation action to simplify the operation.
The sweeping frequency power source of the control power generator of the ultrasonic cleaning machine avoids the ultrasonic power changes caused by frequency drift and the unevenness of the ultrasonic field caused by the dispersion of the resonant frequency of the ultrasonic transducer, improves the cleaning effect of the cleaning machine, and simplifies the operation.
