For the reasons of lacking multiple frequency tracking function of ultrasonic equipment, this paper designs a variable frequency ultrasonic generator the ultrasonic generator based on digital pulse drive,with the function of searching the resonance frequency of the transducer automatically in a certain range,adjusting the output frequency intelligently,and adapting to the transducer with different performances dynamically.System tests expatiate that this ultrasonic generator realizes the function of searching multiple frequency of generator and frequency tracking automatically,which meets the requirement of phase locking of transducer fast and accurately.
