1. The invention concerns a ultrasonic generator system with automatic frequency tuning consisting of an control input and a supply input, on whose output an ultrasonic converter is placed, characterised in that it has a control block of voltage tuned generator (BSGPN), whose output is connected to the first input of voltage tuned generator (GPN), to whose second input is supplied minimal frequency signal (fmin), whereas to the third input is supplied maximum frequency signal (fmax), and the first output of the voltage tuned generator (GPN) is connected to an impulse forming block (BFI), and the second output of the generator (GPN) is connected to the input of control block of voltage tuned generator (BSGPN), while the output of the impulse forming block (BFI) is connected to a control input (S1,...,Sn) of the ultrasonic generator (G).<IMAGE>
