METHOD OF ELECTRIC CURRENT GENERATION BY CONVERSION OF VARIABLE STATIC POTENTIAL AND DEVICE TO THIS END Russian patent published in 2011 - IPC H01L41/113 H02N2/18 

FIELD: electrical engineering.

SUBSTANCE: element pole metal surface tapping off potential from piezoelectric element, opposite the ball (roll) rolling surface is cut into sectors perpendicular to rolling direction. Independent potential tap-off is performed from each said sector generated in transfer and removal of ball (roll) pressure from element section above sector. Proposed method is based on using periodic system of loading and unloading sections of piezoelectric element section above sectors that tap off variable static potential from regular harmonics element to be directed in conductor as AC current. Potential is tapped off identical-phase sectors arranged next but one into two common buses of opposite phase and directed into conversion device made up of dual step-down transformer with earthed primary. Variable static potential is supplied to second end. Variable eclectic current is induced in secondary with frequency corresponding to that of variable static potential.

EFFECT: generation of variable electric current.
