Abstract
A method for selecting a piezoelectric transformer characteristic includes the steps of connecting a primary-side driving section of a piezoelectric transformer to a high-frequency generator while leaving a secondary-side generating section thereof in an open state, causing the high-frequency generator to sequentially generate and sweep a high-frequency signal over a predetermined frequency range, measuring a resonant frequency of an input-impedance-versus-frequency characteristic of the piezoelectric transformer, and selecting the characteristic of the piezoelectric transformer based on the value of the measured resonant frequency.
