ROSEN TYPE PIEZOELECTRIC TRANSFORMER HAVING MULTI- OUTPUT ELECTRODES AND MULTI-LAMP STABILIZER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a Rosen type piezoelectric transformer including a multi- output electrodes having even output characteristics. SOLUTION: The transformer comprises: a piezoelectric element; an input electrode set on upside face of the piezoelectric element and applied by alternating current voltage of a multi-lamp stabilizer; a plurality of output electrodes arranged in the direction of width of the piezoelectric element in a band form and arranged with an equal space outside the input electrode with an equal space and respectively coupled to one end of a plurality of cold cathode fluorescent lamps one to one; and common electrode arranged on downside face of the piezoelectric element facing the input electrode and together coupled to the ground of the multi-lamp stabilizer and the other end of a plurality of cold cathode fluorescent lamps.
