Abstract (en)
[origin: EP2705906A2] The method involves connecting a resonant circuit (2e) with an electro-mechanical oscillating system of an ultrasonic transducer (3). The initial excitation frequency of the resonant circuit is determined. The phase difference between current and voltage of excitation signal is detected for the frequency control of an ultrasonic generator. The oscillating system is excited at initial frequency to ultrasonic vibrations. The excitation frequency of the oscillating system is controlled such that the phase of impedance of oscillating system is set to preset range. Independent claims are included for the following: (1) an ultrasonic generator; and (2) an ultrasonic system with ultrasonic generator.
