ELECTROMECHANICAL TEMPERATURE DIFFERENCE ENERGY CONVERTER OF STEP TYPE Russian patent published in 2021 - IPC H02M3/06 F03G7/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, and more specifically to capacitive energy converters, and can be used to power low-power energy consumers in climatic conditions with a sufficient periodic temperature difference, for example, day and night, or in the flight of an artificial Earth satellite in orbit when entering the shadow of the planet and exiting it. The device converts the energy of the temperature difference, for example, between day and night into electrical energy. The device contains two toothed-wavy railings 1, along which the ball stop 2 moves abruptly, placed in a cup case 3. The ball stop 2 is pressed against the railing 1 with a spring 4. The cup case 3 is fixed at one end of the dielectric traverse 5. At the other end of the traverse 5, the same cup body 3 is fixed. The traverse 5, with a fixed plate of the container fixed on it and a ferroelectric 6, is tightly pressed with the help of springs 7 to a movable plate of the container fixed at the end of a bar of dielectric material 8, which shows a significant change in its linear dimensions when the external temperature changes. In this case, the pressure force of the springs 4 and 7 is calculated in such a way that the spring 4 can hold the traverse 5 stationary with the help of ball stops 2 until, when the spring 7 is stretched, its force is less than the pressure force developed by the spring 4. The advantage of such a device is the more frequent operation of the capacitive converter system during the day, which increases its efficiency by the number of operations per time interval.

EFFECT: increase in the efficiency of energy conversion by the device into the number of operations of the capacitive converter system during the day.
