The present invention relates to piezoelectric transformers, and more particularly to a piezoelectric transformer with multiple outputs supplying stable voltages into a plurality of fluorescent lamps by connecting it to a plurality of fluorescent lamps. According to the present invention, the piezoelectric transformer with multiple outputs comprises a piezoelectric plate, a first input electrode being formed on the top surface of the piezoelectric plate, a second input electrode being formed on the bottom surface of the piezoelectric plate, a plurality of first output electrodes being electrically isolated from each other, which is formed by dividing the remaining portions of the top surface of the plate excluding the surface on which the first input electrode is, and a second output electrode formed in the remaining portions of the bottom surface of the plate excluding the surface on which the second input electrode is formed, which is disposed at a confronting position of the plurality of first output electrode. In case of forming a stabilizer with a plurality of fluorescent lamps, the first input electrode and second input electrode are connected to a AC voltage generator of the stabilizer, the first output electrode is connected to one terminal of more than two fluorescent lamps one to one respectively, and the other terminals of the fluorescent lamps are connected to the second output electrode in parallel. So the present invention provides a stabilizer for lighting lamps without a ballast capacitor by supplying a regular voltage to more than two fluorescent lamps.
