Abstract

A piezoelectric transformer includes a base body. The base body includes an input part and an output part mechanically connected to the input part. The base body also includes internal electrodes perpendicular to a polarization axis of the transformer-in the input part and the output part. The transformer also includes an auxiliary electrode galvanically separated from the input part and the output part.
