MULTI-OUTPUT PIEZOELECTRIC TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide a multi-output piezoelectric transformer capable of stably turning on two or more fluorescent lamps by arranging two of output electrodes or move having uniform output characteristic without arranging ballast capacitor. SOLUTION: The multi-output piezoelectric transformer comprises: a piezoelectric element; a first input electrode set on the upside face of the piezoelectric element; a second input electrode set on the downside face of the piezoelectric element facing the first input electrode; a number of the first output electrodes set by equally dividing and electrically separating each other the remaining part except the first input electrode of the upside face of the piezoelectric element; and a second output electrode set on the remaining part except the second input electrode of downside of the piezoelectric element so that it faces the number of the second input electrode.
