| titleOfInvention |
Ultrasonic generator with a piezoelectric transducer |
| abstract |
In an ultrasound generator, the driver circuit of a piezoelectric transducer (1) is formed with a switching regulator (6) controlled by a microcomputer (5), the pulse duty factor and frequency of which are controlled as a function of the impedance of the transducer (1) detected by a measuring circuit (9) . |
