Abstract :
To perform an effective function of an ultrasonic device for intensification of different technological processes a generator should have a system for an automatic frequency searching and tuning in terms of changes of the oscillation system resonance frequency. This article presents a system of phase-locked-loop frequency control (PLLFC) of ultrasonic generators with automatic resonance frequency searching in the given band of frequencies
