Abstract
In the present invention, a dual-output piezoelectric transformer for driving at least two loads is provided. The dual-output piezoelectric transformer comprises a piezoelectric piece, a set of input electrodes mounted centrally on a first and a second sides of the piece with a first polarization direction along a thickness direction of the piece, and a first and a second output electrodes polarized reversely in a second polarization direction and respectively mounted around surfaces of two ends of the piece with the second polarization direction being a longitudinal direction of the piece.
