FIELD: electrical engineering.
SUBSTANCE: cryogenic piezoelectric generator (CPG) has: a container for storage of cooled liquefied gas. By means of the valves controlled by the control unit, the tank is connected to resonator chambers (having valves for pressure release), in which there are piezoelectric elements. Piezoelectric elements react to changes in pressure in chambers by creation of potential difference at their contacts. Liquefied gas heating system controlled by control unit. Control unit capable of starting and stopping liquefied gas heating, controlling pressure in vessel. Also, valves are opened and closed in resonators for optimum process of current generation with preset parameters by piezoelectric elements.
EFFECT: technical result consists in improvement of CPG and simplification of design.
