GENERATION METHOD OF ELECTRIC PULSE IN INDUCTANCE LOAD OF EXPLOSIVE PIEZOGENERATOR Russian patent published in 2011 - IPC H02N2/18 F42B5/18 

FIELD: electricity.

SUBSTANCE: generation method of electric pulse in inductance load of explosive piezogenerator involves impact loading with diverging wedge-shaped blast wave of piezoelectric converter in which conversion of energy of blast wave to electric energy is performed. Impact loading is formed at detonation of explosive agent. Piezoconverter is made at least of one piezoplate with electrodes on opposite edges. Shock-wave front is perpendicular to electrodes of piezoplate. Then, piezoconverter is loaded with opposite converging wedge-shaped blast wave with time difference Δt between the beginnings of the first and additional loadings of piezoelectric converter, which is chosen from the following condition: Δt=y₀/2D, where y₀ - length of piezoplate; D - detonation speed of explosive agent.

EFFECT: possibility of generation of electric pulse with maximum current amplitude at maintaining the value of allowable voltage on inductance load of generator and reducing the volume of piezoconverter.
