Abstract
A piezoelectric transformer with multiple outputs and a stabilizer having the piezoelectric transformer with multiple output electrodes is disclosed. The piezoelectric transformer with multiple outputs lights a plurality of cold cathode fluorescent lamps at the same time by forming a plurality of output electrodes as one body. The piezoelectric transformer includes a piezoelectric plate; an input electrode formed on an upper surface of the plate; a plurality of output electrodes having an identical band shape, arranged in equal distance in the longitudinal direction of the plate at an outer side of the input electrode, and connected electrically to one ends of the plurality of the cold cathode fluorescent lamps respectively; and a common electrode formed on a bottom surface of the plate, confronting to the input electrode, commonly connected to ground of the stabilizer and other ends of the plurality of the cold cathode fluorescent lamps.
