Abstract:
1. A non-symmetric drive piezoelectric ceramic transformer comprising: a rectangular piezoelectric conductor, wherein said rectangular piezoelectric conductor is divided into a first zone, a second zone, and a third zone along its length, the first zone being an oscillation node adjustment zone, the length of which is adjustable, so as to so as to be able to adjust a resonance frequency and oscillation node of said piezoelectric transformer; the second zone being an input drive zone, the upper and lower surface of which is coated with an electrode respectively, and which is polarized along its thickness; and the third zone being an output generation zone, the output head of which is coated with an electrode and which is polarized along its length, wherein a height (H) of the first, second, and third zones is substantially equal to 2.72 mm.
