A circular cylindrical, radially polarized ceramic shell piezoelectric transformer.
We propose a circular cylindrical shell piezoelectric transformer of radially polarized ceramics operating in thickness-stretch modes. Two theoretical analyses involving different approximations are performed on the proposed transformer using the 3-D equations of linear piezoelectricity. The transforming ratio, input admittance, and efficiency of the transformer are calculated and compared with those of a previously analyzed circular cylindrical shell transformer of axially polarized ceramics operating in shear modes.
