Abstract
Piezoelectric transducer drive apparatus applies varying pulse rates to the terminals of the transducer with the transducer acting as a capacitor and integrating the applied pulses. A conductive path from each transducer terminal remover charge from each terminal. Control of the voltage across the transducer is achieved by individually varying the pulse rates applied to each of the transducer terminals.
