A piezoelectric transformer comprises two piezoelectric cells with electrodes, an electric oscillation source and an electric load. The piezoelectric cells are made as cylinders with longitudinal polarization and electrodes applied to faces which perpendicular and parallel to a face polarization vector; herein, the piezoelectric cells are coupled in a way that orientation of polarization vectors of input and outputs parts of the transformer, input and output electrical fields are coincide; moreover, a signaling wire of the electric oscillation source is connected to the electrodes of first piezoelectric cell, a signaling wire of the electrical load is connected to the electrodes of second piezoelectric cell, grounded wire of the electric oscillation source and electrical load are connected to the middle electrode of first and second piezoelectric cell. |
