Abstract
A multi-layer piezoelectric transformer (PT) is provided having an insulation layer having an input electroactive ceramic layer bonded to one of its major faces and an output electroactive ceramic layer bonded to its other major face. The input layer is electroded on both major faces and is poled in the thickness direction. The output layer has segmented electrodes patterned on its two opposing major faces and portions of the output layer are alternatingly poled in opposite directions across the output layer's thickness. The configuration of the poling and electrodes places adjacent portions of the output layer electrically in series.
