  • Piezoelectric transformer with dual-phase input drive
    Patent number: 6476542
    Abstract: The present invention provides at least two input driving sections for a piezoelectric transformer. The two input driving sections are configured in a stacked configuration, with either one section on top of the other or the sections interlaced. Each input driving section includes a pair of electrodes. All of the electrodes preferably have a distinct electrode shape. The two input driving sections provide for the application of phase-modulated input signals to control the gain or amplitude of the transformer output.
