Abstract: This paper provides a method for frequency control at the ultrasonic high power piezoelectric transducers, using a feedback control systems based on the first derivative of the movement current. This method assures a higher efficiency of the energy conversion and greater frequency stability. A simulation for two kinds of transducer model is made. The method is implanted on a power electronic generator. Some transient characteristics are presented.
