Ultrasonic Generator An ultrasonic generator comprising an ultrasonic transducer having a natural frequency at which the dynamic admittance becomes maximum; a main circuit consisting of a switching circuit or first current regulator and a second current regulator connected in series to said switching circuit or first current regulator, the ultrasonic transducer being interconnected between an electrical source and the junction between said switching circuit or first current regulator and the second current regulator; a driving circuit for alternately driving the switching circuit or first current regulator and the second current regulator at a frequency equal to or substantially equal to the natural frequency of the ultrasonic transducer, thereby supplying the driving current thereto; and a feedback circuit for deriving an AC voltage in proportion to the magnitude of the driving current and feeding back this voltage to the driving circuit.
