Controlling the Polarization of Ferroelectrics to Obtain Additional Energy

Abstract

A small-size installation created using ferropiezoelectric ceramics for generating additional electric power is considered. The use of an electrochemical generator in the plant improves the efficiency of power generation by controlling the polarization of ferropiezoelectric ceramics and applying innovation. At consumption of 1 joule of electricity (due to mechanical energy), 2...4 joules of electricity are generated at the output. The technology of energy increase is realized in two stages: at the first stage the degree of polarization of the ferroelectric element is increased, and at the second stage the electric power supplied to the load is increased. The efficiency of the electrical installation is about 55...60% and depends on the modification of ceramics and electrical circuitry.
