Abstract : This report describes a piezoelectric transformer with a primary which has a plurality of internally electroded piezoelectric ceramic layers. The internally electroded layers are interconnected electrically so that the adjacent layers are electrically poled in opposite directions but driven in phase. The high voltage electrode of the secondary is attached to one end of the transformer which is opposite to the end having the primary thereof, with the low voltage electrode of the secondary connected to one of the primary electrodes. Alternatively, the low voltage secondary electrode can be separated from both of the primary electrodes, thus providing DC isolation between the primary and secondary of the transformer.
