Abstract

In an ultrasonic generator the driver circuit of a piezoelectric converter is provided with a switching regulator under control of a microcomputer, the pulse duty factor and frequency of the switching regulator being controlled in response to the converter's impedance which is detected by means of a measuring circuit.
