Abstract

The invention relates to a variable-section Rosen piezoelectric transformer, which comprises input and output formed by isosceles trapezium piezoelectric sheets, wherein the input and output are connected via interface; the input is polarized along thickness; the output is polarized along length; the upper and lower faces of input have metal electrodes, to form input interface of piezoelectric transformer; the end of output has metal electrode, with the metal electrode at low face of input to form output interface.

Description

technical field [0001] The invention relates to a piezoelectric transformer, in particular to a variable-section Rosen type piezoelectric transformer. Background technique [0002] A transformer is a commonly used voltage conversion device, which can convert the input and output voltages as needed to meet actual needs. The common transformer is an electromagnetic core transformer, which realizes the mutual conversion of electric energy and magnetic energy through two sets of inductive coils. Electromagnetic transformers cannot meet the demand for miniaturization of transformer parts due to their large volume, high energy consumption, low efficiency, and difficulty in miniaturization. Piezoelectric transformers use the force-to-electricity conversion function of piezoelectric ceramics to realize the mutual conversion between electrical energy and mechanical energy, so as to achieve the purpose of increasing or decreasing the voltage. Piezoelectric transformers, especially R...
