ABSTRACT:
A circuit for driving a plurality of ultrasonic transducers uses an oscillator drive means, first means responsive to the current supplied to the transducers is fed back to vary the oscillator frequency to maintain the transducer current at a maximum level, and second means, independent of the first means, are provided to cyclically sweep between upper and lower limits the oscillator frequency determined by the first means. This assures that each transducer experience resonance at least once each sweep.
