Abstract (en)
[origin: EP1738837A2] The method involves using a resonant circuit in supplying energizing current and excitation voltage (U) to the ultrasonic oscillator (1) included in an existing ultrasonic oscillation system. The frequency of the resonant circuit is set outside of the resonant frequency of the ultrasonic oscillation system, and can be set and adjusted by changing size of the energizing current and changing the frequency of the excitation voltage to predetermined value. The size of the energizing current depends on the size of the excitation voltage. An independent claim is included for the switching configuration used in operating an ultrasonic oscillator.
