  • Drive circuit for piezoelectric high voltage generating device
    Patent number: 4054806
    Abstract: A high voltage generating device utilizing a piezoelectric transformer in which an inductance is connected between one of the drive electrodes of the piezoelectric transformer and an output terminal of a drive signal source, and a capacitor is connected across the two drive electrodes so that a variation of the output voltage of the device due to a change in the load is minimized. In addition, the effective range of the frequency characteristic of the output voltage is expanded and the temperature characteristic of the output voltage is improved.
