Abstract
A piezoelectric transformer is provided having segmented electrodes on one or both faces of a piezoelectric ceramic disk. Application of a voltage sequentially to one or more adjacent segments forms a travelling wave in the disk. Application of a voltage to alternate segments forms a resonant standing wave in the disk. The transformer may be configured with a resonant feedback circuit that provides step up voltage transformation, and may provide voltage to multiple loads.
