HIGH-VOLTAGE GENERATOR AND METHOD OF ITS MANUFACTURE Russian patent published in 2015 - IPC H01L41/83 H01L41/22 

FIELD: electricity.

SUBSTANCE: invention relates to piezoelectronics. Essence of the invention: the working body of the high-voltage generator is formed by inertial mass and a package of the plates of polarised composite ferroelectric materials with high values of piezoelectric voltage coefficient and compressive strength pre-set for each plate. The distances between the conducting surfaces applied on the plates is set such that their values multiplied by values of mechanical stress and piezoelectric stress coefficient be identical to each plate in the package. The method comprises the manufacture of each batch of the plates polarised composite ferroelectric materials by consecutive execution of the following operations: preparation of moulding powder of the synthesised material, preparation of mix of moulding powder of the synthesised material and pore agent, moulding from mix of work-pieces and their high-temperature processing by an agglomeration method, machining, metallisation, polarisation and measurement of parameters. The pre-set compressive strength for each batch of plates is achieved by a porosity variation due to change of concentration of pore agent in the plate.

EFFECT: conversion of mechanical compression stress to electric energy without explosive, reduction of time of formation and increase of occurring electric charge in unit of volume of the working body at high values of potential difference.
