ABSTRACT:
A generator for exciting a piezoelectric transducer, includes at least one digital processor unit. The digital processor unit is configured to operate at least in an iterative operation stage including more than two successive iterations. Each iteration includes: exciting the transducer at a plurality of frequencies in a frequency band about a set-point frequency; during transducer excitation, acquiring one or more values related to at least one electrical magnitude associated with the excitation of the transducer for a plurality of frequencies in the frequency band; and analyzing the values acquired to determine a new set-point frequency for a subsequent iteration.
