Використання п'єзотрансформаторного методу для визначення характеристик п'єзоелектричних випромінювачів

Abstract

The piezotransformer has several advantages when measuring dynamic characteristics. In the simplest case, a piezoelectric transformer is a piezoelectric element with three electrodes, forming two systems of electrodes. The piezotransformer circuit is very convenient for determining the inherent only of this object given to the oscillating system of dynamic cha-racteristics. With the help of a piezotransformer method, it is possible to obtain not only infor-mation about resonant frequencies, but also quality factor, bandwidth, internal (own) resistance of the piezotransformer.
