ABSTRACT:
A method for quickly screening piezoelectric transformer apparatuses having low mechanical strength and latent defects is performed by connecting a load impedance to a generator of a piezoelectric transformer apparatus and applying a stress signal to an actuator to vibrate the piezoelectric transformer apparatus. Latent-defect transformer apparatuses having low mechanical strength are damaged during this process and therefore can be easily identified.
