Rosen type piezoelectric transformer with multiple output electrodes

A Rosen type piezoelectric transformer being used for a stabilizer to light a plurality of cold cathode fluorescent lamps, comprising:

• a piezoelectric plate including alternately laminated first piezo-sheets and second piezo-sheets, the piezoelectric plate having confronting side surfaces;
• a plurality of input electrodes formed at the center of the first piezo-sheets in the longitudinal direction of the first piezo-sheets;
• two first output electrodes formed on the confronting side surfaces in the longitudinal direction of the piezoelectric plate;
• a plurality of common electrodes formed on the second piezo-sheets, confronting to the respective input electrodes;
• and
• a plurality of second output electrodes formed between the input electrodes and the first output electrodes on the first piezo-sheets respectively, wherein the distances between the neighboring second output electrodes being identical to each other.
