Abstract

A piezoelectric transformer comprises two piezoelectric cells with electrodes, an electric oscillation source and an electric load. The piezoelectric cells are made as blocks having thickness and length polarization, a cylinder having length polarization and electrodes applied to faces which perpendicular to a face polarization vector; the piezoelectric cells are coupled in a way that polarization vectors of input and outputs parts of the transformer and the input and output electrical fields are perpendicular to each other; moreover, a signaling wire of the electric oscillation source is connected to the first electrode of first piezoelectric cell and second electrode of second piezoelectric cell, a signaling wire of the electrical load is connected to the first electrode of second piezoelectric cell, grounded wires of the electric oscillation source and electrical load are connected to the second electrodes of second of first piezoelectric cell correspondingly.
