Abstract: We perform a theoretical analysis on a ceramic plate piezoelectric
transformer operating with thickness-twist modes. Mindlin's first order theory
of piezoelectric plates is employed. Forced vibration solution is obtained.
Transforming ratio and vibration mode shapes are calculated. The effects of
plate thickness, electrode dimension and inertia are examined. The results are
useful to the understanding of the operating principle and the design
optimization of the transformer.
